Default It Works . . .

Maximus,

What Works - WORKS ! { Oh The Joy of saying... It's Working ! }

The IDEA of using the the built-in Coax Cable TV Distribution
System in an Apartment/Condo Building is one that many Antenna
Challenged Apartment/Condo Residents simply overlook.

NOTE: If not used (subscribed to) often the Coax Cable is
'disconnected' at the buildings Main Distribution Box.
So you have a "Free Run" of Wire from your Apartment/Condo
back to the Main Box. Some times this can be more than a 100Ft.

HOOK=UPS - Try when using the built-in Coax Cable TV Distribution
System in an Apartment/Condo Building:
* Direct Connection to the Center Wire
using the Whip Antenna (Antenna Input)
* Direct Connection to the Outer Shield
using the Whip Antenna (Antenna Input)
* Try Using a 75 to 300 Matching Transformer
- One Lead to the* Direct Connection to the Center Wire
- One Lead to the Radio's Ground

FWIW: This can turn out to be a reasonabily good [Hidden] Antenna.


PLUS - Here are three additional options when using the built-in
Coax Cable TV Distribution System in an Apartment/Condo Building.

1. Use a modified "Portable Wire Antenna" (PWA) as a 'coupler'
between the Coax Cable and the Radio. (Try using theis with the
TV Matching Transformer Connected across the PWA.)

2. Try using a small simple Pre-Selector between the Coax Cable
and the Radio. Two that come to mind are the MFJ-956 or the
Grove Mini TUN-3, also you may wish to take a look at the
Yaesu FRT-7700.

3. High Frequency (Shortwave) 1 MHz to 30 MHz Band Pass Filter
to reduce the VHF and UHF TV/Cable Signals

I connected an alligator clip to the barrel of the cable tv connector - it
works much better than the Radio Shack magnetic mount CB whip antenna LOL.
I'd love to know what you all think about current propogation conditions,
however, so I know if I'm missing much S.

Thanks RHF I put up a few feet of wire in the room along the diagonal.
That works even better, but propogation did not seem that good yesterday.
Unfortunately, the cable is in use
