presented at an International Radio Club of America conference a
couple of years ago
used a Cat-5 antenna as both a Beverage and as feed line from the far end.
However, twisted pair lying on conductive ground has apparently quite
high loss, per correspondence with KD9SV a couple of years ago:
Twisted pair does work for an "above ground beverage" but does NOT
work at all for a "Beverage on the ground"
.

My previous experiences in Italy with reversed Beverages using
twisted pairs from CAT5 cable and later with RG58 coax on the ground
were both negative.
These comments don't sound promising so far as using twisted pair in
a BOG unfortunately.
Anyone with different experience?

Did a first test on a BOG, I noted it didn't have a f/b ratio.
Then I noted I connected the wrong pair to the radio.
That means the twisted pair is picking up signal.
I terminated it hoping that would quiet it, It didn't.
I corrected the wiring error, But the feed line pickup
makes the BOG useless.
On a previous BOG I used #18 twisted speaker wire and it
picked up very little RF when connected the the radio.
Do I need to do anything with the unused pairs,
that would help?
Any thoughts on how to prevent RF pickup by the feed line?
