Oh boy, there is always at least one of these guys around when it comes to
the subject of the G5RV...
I use one on 40/80 @ 45'. In 5 years, I have worked EVERYTHING I have heard
on it. I have scored near the top of my class ( high power) in domestic
contests. Any ( well, almost any) antenna at 45' is going to be poor for DX on
the
low bands. I have over 170 DXCC on 40 & about 145 DXCC on 75/80 with it.
Lemme see you do this with a piece of dacron. Ok???
Yeah, it isn't a yagi. Yeah, you need a tuner. But, I did have a full size 80
meter dipole up, at the same height, same orientation, & doing A-B switching,
i NEVER, ever heard or saw any difference between the 2. Modeling progrmas
might say different, but, my primitive tests show otherwise. I have never had
1/2 wave 40 dipole up, but I would assmue the results would be the same.
Bottom line is this --- If you DO NOT have the space for a full sized 80
meter dipole, a G5RV is great alternative. Period.
