I will say that I can improve my 437 reception by rotating the beam...I also have gotten better signals by aiming the beam at a point on the ground 100 feet away...
Why criticize? Everyone else can do anything they want to their antennas without me getting upset...afterall, it's not MY antenna. Now if someone wants to point me toward scientific theory, antenna modeling programs, propagation theory...then I can stand up and listen...until then, my best signal is most important to me.

This thread just "feels" like a re-hash of an "engineer's view vs. real world results" argument. Like when I was told here - by engineers - that it mattered how I twisted my Arrow while working the sats. "Ya gotta take polarization into account, Clint - there's a 22db difference when you turn your antenna 90 degrees - a tremendous performance hit if you don't take this into account ... " > > Yet in the real world of demonstrating workin' the birds, there's no such performance degradation. I have hundreds of witnesses to this fact: Capture SO-50 and AO-51 with the Arrow and operate TX and RX while twisting the antenna in different angles doesn't change the great reception and transmission quality. > > If you are in the market for an Arrow, I simply suggest that you use it as offered to you. You will be pleased with its 2M and 440 amateur bands performance. And leave the modding of the elements w-a-y on the bottom of your "things to do" lists. > > Clint Bradford > > ---------------------------------- > Clint Bradford, K6LCS > http://www.clintbradford.com > _______________________________________________ > Sent via amsat...@amsat.org.
