Instructions for Putting up a Long-Wire Antenna

Posted: 11 Apr 2020 04:20 PM PDT
http://www.iw5edi.com/ham-radio/3792/instructions-for-putting-up-a-long-wire-antenna



Ive actually used this kind of antenna. When I was a teenager, I used it
with my old Realistic stereo receiver to improve its AM reception, and it
did work. (My dad put it up for me.)








Note: RadioShack sells this antenna as a kit, catalog # 278-758, $9.99 in
their 2000 Catalog. You might also find it from other electronics
suppliers. They sell the antenna wire as catalog # 278-1329, $6.99 in the
same catalog. The insulators can be ordered for shipment to your house
through RadioShack RSU catalog # 12099248, $4.79 + shipping in the 2000
Catalog.




Find two points, such as two poles (NOT utility poles!), or as most people
will do, the corner of your house and a tree. Any safe places above the
ground from which you can string this wire will do. Remember that not just
the mounting places, but the air-space through which the wire will be
strung must be free of obstructions, such as trees, and especially power
lines. Whatever you do, dont put it on the same corner of the house through
which your electrical service enters! First, that will be dangerous, and
second, youll pick up power line noise.








This antenna picks up signals best at right angles. It picks up worst
end-on. Therefore, remember to orient the wire to pick up from the
direction in which you are most interested.




Using an eye-hook at each point, attach a length of nylon rope. Tie the
other end of the nylon rope to each insulator. The bare copper wire is
strung from between the insulators, as shown in the diagram.




Use an insulated wire to connect to the copper wire at the end closest to
your radio. Strip a couple inches of it and wrap it around the bare copper
wire. For best results, solder this connection. This is shown in Figure 2.








If you string the wire from a stationary point (such as a house) to a tree,
use this trick that my father taught me, and that Ham Radio operators use.
You see, the tree will sway in the breeze, stretching the wire over and
over, eventually breaking it. So on the tree, instead of using a plain
eye-hook, put up a pully (such as a clothsline pully). Run the nylon rope
through this pully, letting a few feet hang down, and tie a brick (or
suitable heavy weight) to the end of the rope. This is what I have
illustrated in the first diagram. As the tree sways in the breeze, the rope
moves feely through the pully, and the weight of the brick keeps the whole
thing taut.




Grounding: From the ground terminal on your radio (next to the antenna
terminal) run a wire to either a copper cold-water pipe (PVC pipe wont
work) or a copper ground rod driven into the ground.



Some safety notes:




1. Keep your antenna far away from power lines! If you, your antenna or
your ladder touches a power line, you could be KILLED.




2. Remember that you will be climbing ladders or trees to high place.
Observe every safety precaution. Never extend the ladder beyond the
manufacturers reccomendation. Never stretch to reach a point instead, move
the ladder. Have the ladder on a secure footing, and have someone there to
hold the ladder.




3. Make sure your antenna is in a safe place, high enough so people or pets
wont walk into it by accident. (Plus, the higher up you get it, the better
it works).




4. Use lightening protection! Make provisions to disconnect and ground the
antenna when not in use. C. Crane Company and RadioShack offer lightening
protection devices. However, disconnecting and grounding the antenna is
still the best option. RadioShack sells a simple knife switch you can use
for this. Screw it to the wall or table next to the radio, hook one side to
the antanna, the other to a wire leading to a copper grounding rod, or the
copper cold-water pipe leading outside of your house. (Remember this doesnt
work if you forget to throw the switch!)

The Vertical Bazooka Antenna

Posted: 11 Apr 2020 03:52 PM PDT
http://www.iw5edi.com/ham-radio/3777/the-vertical-bazooka-antenna



An article by VE3VDC LD Blake




Every radio amateur should build at least one antenna to prove to
themselves they can improvise in an emergency. One of the easiest and
quickest antennas to build is the Vertical Bazooka, which is made entirely
from coaxial cable.












Beyond being extremely easy to build, these antennas have several nice
features to recommend them:



Total cost under $10.00cdnNo coils needed.No ground radials.SWR under 2:1
across several megahertzCan be built as part of your feedlineCan be coiled
up and put in your car trunk.Performance like regular half-wave
antennas.Self-supporting versions are easily built.




The antenna itself is an off-center fed vertical dipole made by flipping an
electrical quarter wavelength of braid back over the outside of the coax.
The center lead of the coax forms one half of the dipole and the braid
forms the other. The resulting antenna has a low radiation pattern and an
impedance of 55 60 ohms.




One of the more interesting features is the braid itself. By folding an
electrical quarter wavelength of braid back over the insulated coax we are
forming both a dipole and a bazooka (sleeve) balun, a coaxial 1:1 balun
that greatly reduces feedline radiation. The braid side of the dipole ends
up considerably shorter than the top element because of the interaction
between the braid and the coax. The outer braid couples with the inner
braid to form the balun and is thus affected by the velocity factor of the
coax.




You can use the formulae in the diagram above to create Vertical Bazooka
dipoles for any frequency. But please notice the formulas shown will
deliberately start you off with the top section too long, so you will have
to trim it for the best SWR.




You can build a mobile emergency version of the Vertical Bazooka by
attaching a length of non-conductive cord (nylon line) to the top of the
antenna. With a weight on the free end of your cord, you can simply toss it
over any nearby support and hoist the antenna up into the air for use.




If you like you can also build a self-supporting version by sliding the
finished antenna into a length of Schedule 40 PVC plumbing pipe.

Cables Velocity Factor




The only things you need to build a Vertical Bazooka are a length of coax,
a connector to fit your radio and a length of heat shrinkable tubing. All
these parts should be readily available from your local electronics parts
or ham radio stores.




The antenna is made by removing the outer covering of the coax for the
length of the top section, flipping the braid back over the outer covering
of the bottom section and then trimming the braid to length. Once you have
this done the task is that of trimming the upper section for best SWR.




The first step is to figure out the lengths of the various sections of the
antenna. You will need to know the velocity factor of the coax you are
using to get this right. A chart showing the VF of some of the more common
50 ohm cables is at the right.



Calculate the overall length of the antenna using the formula:
Length = 15000 / center band frequency = Centimetres
For example: On 2 metres this gives us 15000/146 = 102.8 cm.  Calculate the
length of the lower section:
Braid = (7500 / center band frequency) x VF = Centimetres
Eg. On 2 metres with RG-8x: (7500/146) x .78 = 40.1 cm.  To position the
feedpoint we calculate:
Top = Length Braid = Centimetres
Eg. On 2 metres with RG-8x: 102.8 40.1 = 62.7 cm




The first step in construction is to remove the outer jacket of the coax
from the top section.




Measure down the length you calculated for the top section and make a cut
around the coax jacket. Be very careful not to cut the braid. I find it
helpful to fold the coax over my finger, to put stress on the jacket and
cut very gently with a knife until the braid is visible in a small spot,
then rotate the coax and cut again, until the entire circle is cut.




Now cut along the coax making a lengthwise slit in the outer jacket until
you get to the end. Again be very careful not to slice the braid. Removing
this section of jacket will expose the braid as shown on the left.




Now comes the part everyone has trouble with. We need to flip the braid
back over the outer jacket of the coax.




Starting at the end of the coax work the braid lose from the insulation
over the inner conductor. This works like chineese handcuffs in that as you
push back the braid will expand a bit and become free to move along the
center insulator.




Once you have the braid free to move, simply grab it an inch or two above
the bottom of the exposed part and push it back over the coax in short
sections. Once you get the first section over, move down a bit and continue
with the next. Once you get it started, it will actually go quite easily.




On the right we see a close-up of the feedpoint of the antenna. This is
actually at the end of the outer jacket and was formed when you flipped the
braid over.




Now smooth the braid down tightly over the outer jacket and put a bit of
tape at the bottom to hold it in place.




The next step is to trim the braid to length. Measure down from the
feedpoint (the top of the braid) and put a tight band of tape around the
braid so that its bottom edge is where you want to cut. Now using fine wire
clippers, clip the braid to the final length you calculated.




On the left we see a shot of the antenna with the bottom section trimmed to
length. The formulas we used get the length of the braid very close to what
it needs to be and its not terribly critical so this would be a good time
to cut a length of heatshrink to cover the feedpoint and braid with a few
centimetres extra on each end. You can use a heat gun or blow drier to
tighten it into place.




If you are building an emergency version of the Vertical Bazooka you can
make the remaining length of coax (the feedline) almost any reasonable
length. If you are building a stand alone version you will want to leave
enough below the braid to attach a connector once its in its housing.




Finally install a connector appropriate to your radio or feedline. For
emergency versions that will be used with a HT you can use BNC or SMA
connectors. For use with a mobile radio, a PL259 will likely be needed. For
stand alone versions, a PL259 and a double female coupler, is probably the
best bet.




Thats it, the antenna is all ready for its tuneup







Tuning The Vertical Bazooka




The Vertical Bazooka is easily tuned by clipping short sections from the
end of the exposed center conductor of the antenna.




There are, however, some precautions you must observe. This is a dipole,
which means it has easily disturbed high impedance nodes at both the tip of
the top section and the bottom of the braid. It is an absolute necessity
that you get the antenna out into a clear area for tuning. If at all
possible, you want at least 1/2 wavelength of clear space all around the
antenna. More is better.




Probably the best strategy is to tape the antenna to the side of a length
of white PVC tubing so that you can stand it up during tests and tilt it
over to clip the top section. Alternatively you can temporarily attach a
non-conductive cord and hoist the antenna up and down from a tree branch or
clothesline, being careful of the clearance requirements.




Also please note, these clearance requirements include you as your body
capacitance can upset the readings. If youre building an emergency version
its no problem as you can simply play out the feedline and work from the
other end. If youre working on a self-supporting version you will need to
add a length of feedline to enable you to get back from it during tests.




Once you have the antenna in a testing position, take SWR readings at the
top and the bottom of the band youve cut the antenna for. Your first
readings will (hopefully) be terrible, with the bottom of the band reading
a little bit better than the top. This will tell you the antenna is too
long so youre set to begin trimming.




With the formulas used it is very unlikely the antenna will start out too
short.




You should note that you will not likely get a flat match or 1:1 SWR from
this antenna. Its feedpoint impedance varies from 55 to 60 ohms, so you
should be happy with anything under 1.5:1.




Assuming the antenna starts out too long:



Clip a few millimetres from the free end of the top section.Repeat your
band edge measurements.If the low end of the band is still better than the
high end, go to step 1.If the low end and high end readings are equal, you
are done.




As you are clipping, the SWR at the low end of the band may come down then
start to move back up. Thats ok, its just the antennas resonant frequency
passing the low end of the band. Once you complete the clip and test cycle
the resonant frequency should be near center band and you should have an
SWR curve that has equal readings at both band ends and a somewhat lower
reading in the center.



Deploying the Antenna




So, now that you have it all tuned up, the next step is deployment.




If you are working on an emergency coil up version of the antenna you will
want to add a good length of non-conductive cord, such as nylon twine or
light rope to the antenna with a small weight at the loose end. This will
let you spin the weight up on the end of the line and toss it over a tree
branch (or other handy hanging point) and then use the line to pull the
antenna up into operating position.




The best way to affix such a line is to solder a ring terminal or wire loop
onto the end of the top section of the antenna. The trick is to do this
without changing the length of the antenna.




Strip away the center leads insulation so that you can slide the ring
terminal on far enough to get the top of the ring even with the end of the
wire. Slide on the ring terminal and solder it into place, then trim the
wire out of the way of the ring terminals opening.





If youre working on a self-supporting version of the Vertical Bazooka you
will need a piece of white PVC schedule 40 plumbing pipe long enough to
make a radome with allowances for a mounting gap and attachment to a mast
pipe. This will need to be large enough to hold the coax but not so large
as to let it sag inside. 1/2 PVC will hold antennas made from RG-8x and
RG-58 nicely. For RG-8 or other large coaxes you can use 3/4.




The length of the radome can be a problem at lower frequencies. As the
length increases so does its tendency to sag or move about excessively in
the wind. About the practical limit with PVC radomes is 6 metres (54mhz).




The mounting gap cannot be ignored. You will need a gap between the bottom
of the antenna and the mounting structure at least the length of the braid
section if the antenna is not to be detuned by the mastpipe. Longer is
better, within reason.




There are several methods you can use to secure the antenna inside the
radome. My suggestion would be to attach the ring terminal, as above, then
drill a small hole at the top of the pipe and catch the ring in a wire-tie.
No matter what method you use you do have to take some precaution to make
sure its not going to find its way out.




And, of course, dont forget to put a weather cap on top of the radome.



Usage and Conclusions




Ive used the Vertical Bazooka both on my balcony and as a backpack antenna
on a recent day trip with my bicycle. I find its performance to be about
average; that is, what youd expect from a dipole. When hanging from a tree
branch it will open repeaters 25 and 30km away on my HTs medium power
setting. From my balcony that range is almost doubled.




The SWR of the antenna isnt bad. My 2 meter versions came in at about 1.3:1
on each end of the band, about 1.2:1 in the center.
