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.

IV3PRK Pierluigi "Luis" Mansutti (ex HC1PF)<http://www.iv3prk.it/new-page.htm> 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. www.iv3prk.it [http://www.iv3prk.it/user/image/hc1pf-bog-2_archivos-image002.jpg]<http://www.iv3prk.it/hc1pf-bog-2.htm> IV3PRK Pierluigi "Luis" Mansutti (ex HC1PF)<http://www.iv3prk.it/hc1pf-bog-2.htm> 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. www.iv3prk.it Enviado desde Outlook<http://aka.ms/weboutlook> ________________________________ De: Topband <topband-boun...@contesting.com> en nombre de Ashraf Chaabane <ash.kf5...@gmail.com> Enviado: martes, 9 de octubre de 2018 10:07 Para: topband@contesting.com 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! -- Ash ~ 3V8SF <http://www.kf5eyy.info/>Topband: *http://www.kf5eyy.info/topband.htm <http://www.kf5eyy.info/topband.htm>* Phone/SMS/Whatsapp: (+216) 22670026 Skype: kf5eyy _________________ Topband Reflector Archives - http://www.contesting.com/_topband _________________ Topband Reflector Archives - http://www.contesting.com/_topband
