For the Gold Standard SBGH antennas here;
http://www.jedsoft.org/fun/antennas/dtv/gh.html#toc-2
...can these be build using 6 gauge copper wire for the reflectors (as well as the element) - or would that be too soft? These half-wave reflectors range in size from 12 5/16" for the GH4 (probably fine) up to 21 7/8" for the GH10. Might a 21 7/8" a copper wire supported on only one end start to sag after awhile?
2nq q, how do you interpret F/B ratio charts (again on http://www.jedsoft.org/fun/antennas/dtv/gh.html#toc-1 )? I did my research on wiki & know F/B ratio refers to the antenna's ability to pic up signal from the rear. The implication in the noted site is that a high F/B ratio is good - is this because rear-rejection of signals is considered good or do I have that backwards? Just a bit confused - if I got additional channels from the rear I'd be happy (I realize they might interfere with the channels from the front).
