Got that Car/Truck AM/FM Radio in the Home :
Now You Need an AM/MW Antenna or Two !
http://groups.yahoo.com/group/Shortwave-SWL-Antenna/message/9356
So now you have your Car/Truck AM/FM Radio with a
Power Source and Speakers connected to it; and all
packaged in in a nice box of cabinet located in your
Home for some great AM Radio Listening .
All that is left is the... Oops ! The AM/MW Antenna :o)
TWO AM {MEDIUM WAVE} ANTENNAS CHOICES :
VERTICAL 'WHIP' OMNI-DIRECTIONAL ANTENNA :
For General Listening a reasonably good Omni-Directional
Antenna to use with a Car/Truck AM/FM Radio used in a
"Fixed" location; consider using a CB 104" Stainless Steel
Whip Antenna that is mounted on a piece of 21 Foot piece
of Top Rail.
* Locate the Top Rail about 25 to 50 Feet away from
the House and any Utilities.
* A proper Antenna Insulated "Mount" is required to be used
between the Whip and the Top Rail.
* Use a 75 Ohm Coax Cable and Run/Route Coax Cable
50 to 100 Feet of Coax Cable from the Whip Antenna
to the location of the Radio inside the House.
* Connect the Center Wire of the Coax Cable to the Whip
Antenna Element and the Outer Shield to the Top Rail.
* Terminated the Coax Cable with a Motorola Plug.
* The Base (Butt-End)) of this piece of Top Rail
should be 3 to 5 Feet in the Ground using a 6"-8"
Diameter Concrete Anchor and allow the Top Rail to
be Free Standing.
NOTE: The piece of Top Rail is both your Antenna and
Car Radio Grounding Point.
FWIW - The CB Whip Antenna on top of the Top Rail
is also a fairly good Omni-Directional FM Antenna.
DIRECTIONAL AM/MW LOOP ANTENNA :
Another Directional AM/MW Antenna to use with a Car/Truck
AM/FM Radio used in a "Fixed" location is a One-Metre (1m)
AM/MW Loop Antenna.
IMHO - AM/MW DXing "Requires" a Good AM/MW Antenna.
If you are serious about listening to 'distant' Programs
during the Day and Late Night DXing : Then you must
consider building a Large Loop Antenna.
NOTE - Such Large Loop Antennas in the past were called
a Sports Fan's Box Loop Antennas. These are usually
Three to Four Feet Square Box Loop Antenna's that are
'tuned' and 'positioned' indoors, out-side or even in
the Attic for that distant AM/MW Radio Station that
broadcasts the Radio Programs that you wished to Hear.

The-Bottom-Line: For the Best AM/MW Reception requires
the 'right'AM/MW Radio and matching AM/MW Antenna working
together in "Combination".

A 5/8 wave CB whip is 102'', not 104''
If you want car radio type MW antenna performance get an MFJ-1024.
Makes my ICOM R-75 into a mofo. I have mine on top of 2 fence rails
(20' in the air).

You Need an AM/MW Antenna
- CB Whip Antenna on Top Rail vice Active Antenna
http://groups.yahoo.com/group/Shortwave-SWL-Antenna/message/9367
David -Note- " A 5/8 wave CB whip is 102'', not 104'' "
-R- That could be true that they measure out to be 102" vice 104"
-BUT- That would be about a 1/4 WL in the CB or 10m Bands.
CB Low Band 1/4 WL Antenna : = 234 / 26.965 = 104"
CB High Band 1/4 WL Antenna : 234 / 27.405 = 102"
Concerning the MFJ-1024 Active Antenna that covers
50 kHz to 30 MHz. I would agree that a MFJ-1024 is
a good Active Antenna for use with many Radios.
http://www.universal-radio.com/catalog/sw_ant/1132.html
These other Out-Side Active Antennas also could be
use for a good external Antenna with most Radios.
* Sony AN-1 Active Antenna
http://www.universal-radio.com/catalog/sw_ant/2206.html
* Dressler ARA60S Active Antenna
http://www.universal-radio.com/catalog/sw_ant/4061.html
* McKay Dymek DA-100E Active Antenna
http://www.universal-radio.com/catalog/sw_ant/0328.html
* RF Systems DX-10 Professional Active Antenna
http://www.universal-radio.com/catalog/sw_ant/2868.html
* RF Systems DX-One Professional MkII Active Antenna
http://www.universal-radio.com/catalog/sw_ant/1246.html
- - - How ever these do require the use of AC / DC Power
and a simple "CB" (10m) Whip Antenna sitting on top of
a piece of 21 Foot long Top Rail does not.
WHY TOP RAIL ?
The use of the single piece of Top Rail creates :
* A "Free Standing" Antenna Support Structure
with a relative small ground foot print.
* Allows the location of the Antenna Element {The Whip} :
Away-from-the-House or Above-the-Roof and By-Itself.
* A solid 3-5 Foot earth Grounding point for both
the Antenna and Radio.
* Plus it Elevates the Antenna's Whip Element about
twice it's height above ground level 16 to 18 Feet.
TIP - Route the Coax Cable straight down the Top Rail
to ground level and secure it to the Top Rail every
few feet.

The most efficient Mobile CB Antenna is the 102" Whip.
If you desire the best performance, the standard 102"
(Quarter Wave Length 1/4WL) Whip Antenna is the answer.

5/8 Wavelength Vertical "CB" Antenna {11 Meters}
The 5/8 WaveLength rating the Antenna is about 22 Feet
long (5/8 of 36 feet).
http://www.signalengineering.com/ultimate/verticals.html
Also show are the Half WaveLength (1/2 WL) Vertical
and the Ground Plane Antenna.
Doing the Math : for "CB" 11 Meters
- - - 11 x 3.28 Feet = 36.08 Feet
1/4 ~ 9 Feet
1/2 ~ 18 Feet
5/8 ~ 22.5 Feet
3/4 ~ 27 Feet
