David,

is also pretty good stuff too. ~ RHF
http://www.davisrf.com/coax.php#buryflex
-But- It Too Is Over Kill For Shortwave Radio Listening (SWL)
"Receive Only" Antennas.
? WHY Use RG6 Quad-Shield Coax Cable over RG8 and RG58 Coax
Cables for Shortwave Radio Listening (SWL) Antenna feed-in-lines ?
Practically Speaking Coax Cable Attenuation and Cost :
http://en.wikipedia.org/wiki/Attenuation
For a "Receive Only" Shortwave Radio Listener's (SWL)
Coax Cable feed-in-line RG6 Coax Cable still has a lower
dB Loss per 100 Feet then RG8 and about 1/3rd the Loss
of RG58 Coax Cable measured at 10 MHz.
http://www.davisrf.com/coax.php#attenuation
Plus most of the time RG6 Quad-Shield Coax Cable will
Cost-U-Less then RG8 & RG58 Single-Shield Coax Cable.
The Key Characteristic that both RG8 and RG58 Coax Cables
have over RG6 Coax Cable is that the Outer-Shield is "Copper
Braid" which makes them both better at handling RF Power
for Transmitting then the RG6 Coax Cable.
The Key Characteristic that Quad-Shield RG6 Coax Cable has
over both RG8 and RG58 Coax Cable is the Four Outer Shields
for better protection against extraneous RF Signal Penetration :
Since RG6 is by-design a Coax Cable that is most often used
in "Receiving Only" applications such as 'Free' Over-the-Air TV,
Cable TV, and Satellite TV; for Weak Signals and Signal Protection.
IMHO - Quad-Shield RG6 Coax Cable is a natural choice for
many Shortwave Radio Listeners (SWLs) looking to Reduce
and Eliminate the Ingress of RFI and EMF into and along their
Shortwave Antenna's Coax Cable feed-in-line.
COST - Often Quad-Shield RG6 Coax Cable has a Lower Cost
per Foot then both RG8 and RG58 Coax Cables.
EXAMPLE - 100 Feet of Quad-Shield RG6 Coax Cable at WalMart
http://www.walmart.com/catalog/product.do?product_id=7811235
for $33 which is 33 Cents per Foot -vice- 69 Cents per Foot for
RG8 Coax Cable at a Amateur {Ham} Radio Specialty Store.
AVAILABLITY - Also Quad-Shield RG6 Coax Cable is just
about Available Anywhere from : Home Depot, to WalMart,
to Ace Hardware, etc.

Planting your coax at least 12' down can dramatically reduce common
mode noise originating in your home from reaching your antenna!
In repeated tests in the 'real world' and my lab I was unable to
detect

different receivers.
R2000
DX398
R390
R392
R8B
AOR 7030+
And every other receiver I could lay my hands on.
Pick the cheapest cable with the best braid and that is rated for
direct burial.
An advantage of the quad shield is the reduction of 'transfer
impedance' signal
ingress of MW signals. Very few people will live close enough to a MW
station to
experience worry about this minor problem.

Well, "John Doty" in the reference above says:
> Any *unshielded* [my emphasis added] conductor in your antenna/ground system is capable
> of picking up noise: the antenna, the "lead-in" wire...
First of all, isn't the "lead-in wire" (coaxial cable in this
discussion) -shielded- ? So according to his -own- statement, coax
shouldn't have to be buried, at least from a noise mitigation viewpoint.
Doty continues:
> You can keep noise currents away from the antenna by giving them
> a path to ground near the house, giving antenna currents a path to
> ground away from the house, and burying the the coaxial cable from
> the house to the antenna.
In the 1930s, Bell Laboratories, while investigating power line
influence on telephone cables, proved that burial had NO effect on noise
being induced into the telephone cables; i.e., 20 feet of aerial
separation, from a noise standpoint, was exactly the same as 18 feet of
aerial separation plus being buried 2 feet deep.
Hmmm...should I believe "John Doty" or Bell Labs? You're a smart guy --
I'll let you figure that one out for yourself. :-)

Well, I don't know about the "1990's" (isn't this the 2000s?), but it
became a big issue in the 30s due to the rapidly expanding
electrification of America.

Undeniable Fact # 3 - According to a direct quote of Doty, UN-shielded
lead-in wires are susceptible to noise. Coaxial cable is SHIELDED. So
why does Doty say bury it?
Undeniable Fact # 4 - Even though the RFI environment has changed and
even though man's ability to measure it has changed, burial in a few
inches of soil provides no noise mitigation.
Undeniable Fact # 5 - Yes, the environment has changed and measurement
techniques have changed, but that does NOT mean the Laws of Physics have
changed.
Finally, for the sake of this discussion, assume your
neighbor/neighborhood is throwing out a lot of RF hash and trash.
Furthermore, let us assume you've buried your coax in hopes of
alleviating the problem (even though it won't).
What, pray tell, is to keep this neighborhood RF hash and trash from
impinging directly on the antenna itself and being piped right in to
your receiver?

Let's examine what you just said above.
You want me to re-invent the wheel, re-plow the same ground and
duplicate the work already done by the PhDs at Bell Labs?
To put it another way, you imply it's OK for RHF to quote "John Doty"
but that it's not OK for me to quote Bell Labs. This is one of your more
brilliant comments, Sparky.
> Why should we read you posts...

If you -don't- read my post, how would you know what person I am
referencing? Again, positively brilliant of you, Sparky.
In any event, the Bell System Practices (BSPs) addressing this issue,
still in use to this very day, are proprietary. However, I imagine you
could reference the public 'Bell System Technical Journal' issues of the
era. And, yes, please DO read the "person" I reference (although the
Bell Labs are not "a person"). You will then find that what I say is true.
> You think you somehow improve the information?
Please point out where I ever said or implied anything about "improving"

Period. There's just no end to your brilliance, Sparky.

Looking at the opposite side, that of the way coax is used at the
transmission end, there are a number of relevant situations.
AM broadcast stations using series fed towers (those with an antenna tuning
unit to couple to the tower right above the base insulator) generally bury
the coax that feeds the ATU and tower. The reason is not for any kind of
additional isolation or insulation, but to keep the cable where falling ice
from the tower or guys, storm debris (in hurricane areas, particularly)
can't hit it, and to make it safer from vandalism.
Buried cable installs are also cheaper than the preferred system, which is a
set of poles, metal or wood, above the ground, with a metal bar or roof
above it to prevent ice damage. The advantage of above ground is that the
cable is accessible for repair or replacement in case of internal arcing and
more immune to digging by morons from the telco or electric utility.
Generally, the decision to bury is one of cost, not of RF.

There was nothing in your own words just the references. Again your

Rods and Transformers.
Number "5" is realy only important when you have first
accomplished Numbers 1~4.
Effectively the Buried Outer-Shield of the Coax Cable is/does :
# 1 - Connects both the Antenna Ground and the House's
Feed-in-Line Entry Ground {RadioShack Grounding Point} :
-Thus- "Bonding" these two Grounds.

# 2 - Functions as a Ground Radial for the Wire Antenna
Element to 'unify' the "Ground Effect" {Ground Conductivity
Efficiency} between the two Ground Rods.

# 3 -IF- The Wire Antenna Element is hung in the Air 'over'
this Buried Coax Cable it is in-effect a Counterpoise to the
Wire Antenna Element.

You come to this news group with your trash talk everyday and you have a
problem when I poke sticks at the latest troll to visit the news group.
Well thats just to bad. I don't care what you think. You never
contribute information here. You are a member in very poor standing.
As long as I'm not as obnoxious and strange as you I'll be OK.
When is the last time you made an on topic post? A few months ago last
year? Maybe one or two at most.
Do everyone that reads the news group a big favor and go someplace else
or grow up. Take your pick.

# 4 - Digging the Trench to Bury the Coax Cable feed-in-line
Opens-Up-the-Ground ! -meaning- You now have a Trench in
the Ground to place 'things' in.
http://en.wikipedia.org/wiki/Ground_conductivity
* While the Braided Outer Shield of the Coax Cable can 'connect'
the two Ground Rods at each end of the feed-in-line : It is not a
Solid Copper Wire.
http://en.wikipedia.org/wiki/Ground_%28electricity%29
* While the Braided Outer Shield of the Coax Cable can 'be'
a Ground Radial between the two Ground Rods at each end
of the feed-in-line : It is not a Solid Copper Wire.
http://en.wikipedia.org/wiki/Radial_%28radio%29
TIP - While the Trench is Open : Place a Solid Copper Wire
in it to :
http://www.chem.hawaii.edu/uham/radials.html
* Better Connect {Bond} the two Ground Rods at each end
of the feed-in-line.
* Be a Better Ground Radial in the Ground then the Coax Cable
can be by itself.

* Solid Bare Copper Wire to 'connect' along it's full lenght
with the Earthen-Soil {Ground} that it is laying in.
http://www.bencher.com/pdfs/00361ZZV.pdf
* # 16 AWG or Larger - In the trench running parallel with the
Coax Shield # 16 AWG Solid Bare Copper Wire will do OK.
http://www.radiobooks.com/products/grw1k.htm
-but-if- you happen to have a coupl of hundred feet of # 12 or #14
Insulated Solid Copper Wire laying around; and want to Strip
the Insulation off-of-it to use as for Ground Radials - Go For It !

The Radial "Rule-of-Thumb" for Receive Only Shortwave Antennas :
The More Radials the smaller the Radial Wire that can be use;
with # 16 AWG being about the smallest.
http://www.davisrf.com/ham1/grndwire.htm
16~18 or more Radials : # 16 AWG Solid Bare Copper Wire
8~9 Radials : # 14 AWG Solid Bare Copper Wire
3~4 Radials : # 12 AWG Solid Bare Copper Wire
Single Wire Counterpoise : # 10 AWG Solid Bare Copper Wire
http://en.wikipedia.org/wiki/American_wire_gauge
The Guiding Principle of Radials : The More Radials The Better.
