- Reflector crew. . . Just a thought on the triband testing thread. I work in the land mobile business (for Motorola) and have had my fair share of experience over the years with antennas used in our i

- Yes, I guess a more accurate test would be to run them all in vertical polarization on a fiberglass mast or end mounted for gain comparisons. Then mount them on a PVRC mount and flip them vertically

- Dave and Ty mentioned using vertical polarization for triband tests. This is usually NOT recommended for HF antennas on a ground-reflection range using the gain-transfer method. As stated in the IEEE

- Hi Dave, Then your test is a good one. First, the antennas are vertically polarized and at VHF and so don't face the same problems as measuring an antenna where a shift in polarity could produce extr

- His recommendations do not apply since we are not talking about ground-based antennas! Dave and Ty mentioned using vertical polarization for triband tests. This is usually NOT recommended for HF ante

- Hi Roger, For the very same reason, a LONG test distance is also not recommended for horizontal antennas. Moisture content, soil conductivity, and scattering all affect field strength since at a long

- It seems to me the best test for a tribander is two or more at similar heights not very far apart, and the test begins: Number one number one number one Number two number two number two et cetera...

- Tom: You have some very good points (as usual). I certainly wasn't meaning to advocate vertical polarization for HF yagi test! I'm still not sure how one goes about measuring relative (much less abso
