Claims Made in Video-No.2 :- Polishing cylindrical metal rod (of old LNBF) placed just under lid of waveguide improves signal quality. And cleaning vertical & horizontal polarization probes with thinner/spirit, with the help of cotton and tweezer also contribute to signal growth.
Few Questions :-
1. What is the role of this cylindrical metal rod in waveguide ? Is changing this cylindrical rod with any other high electrical conductivity metal like silver or silver-plated or any silver alloy may have potential for further improvement in signal quality?
2. Should pin shaped polarization probes be cleaned annually/biannually to keep the old LNB running smoothly without any degradation in signal ?
3. What is the role of the lid fixed at the top of waveguide w.r.t signal variation ? From the video one can observe that removing lid decreases signal and again placing increases the signal.
