Hi, Rash.
You can look in the links that I put.
IV3PRK explains how to adjust (gain and F/B) in a BOG and an RBOG.
These explanations were very useful for me to improve my RX antennas.
Hope this can help you.

The Reversible BOGs at HC1PF At last achieved my best solution with receiving
antennas . After trying every kind of receiving antenna I came to the
conclusion that the only one functioning in my environment was a Beverage on
ground, outside of my wall and electric fence and far from the power lines but,
after a few days of happiness, a bulldozer entered in that terrain and….no more
BOGs.

The BOG’s at HC1PF. Finally getting them to work, and definitely the best, but
what a sad epilogue! So, after the disappointing experiment with the horizontal
loop, I decided to get out of my wall and try a Beverage on ground.

Asunto: Topband: Beverage F/B using oscillator
Hi All,
I used a 1.843 oscillator to check NA beverage F/B. The mesurements were
taken 160m away from each end of the antenna. Noise level was constant. I
had 4 dB difference between front and back signals.
Is that what I should expect? Is 1 wavelength distance enough to do this
experience?
This will be repeated with different terminations and I want to make sure
I'm doing it correctly. It will also be applied on the newly installed BOG
to determine optimum length.
Tnx and see you on the air!
