- Hi All I wonder how it would work to put a coil balun between the 40 and 80 meter antennas. Would it help with any interaction? 73 Tom W7WHY -- FAQ on WWW: http://www.contesting.com/FAQ/towertalk Sub

- or a If you use a common feedpoint, keep some separation between the two dipoles. I tried running a 75/40 dipole with close spacing and had trouble with the 40 meter version, couldn't get the SWR do

- Hi Guys, We are thinking of replacing our old G5RV at the hospital with a new G5RV or two dipoles on a common feed point cut for 40 and 75M. We want this for local emergency communication among the i

- Does the G5RV require a tuner for one or both bands? 80 / 40 dipoles can be made independent of each other by placing them at right angles to each other with a single feedline. As the wires come clos

- Tom's right. The antenna to use in that situation is a vertical. I had an R-7, a A3S, and a G5RV above a tin roof on a 14 story building in Moscow. The G5RV was useless, and the R-7 was in many case

- Hi Ted - Go with the dipoles. Right angles to each other would be best, of course, but even a smaller angle will help the interaction problem. Some of the respondents apparently overlooked your refer

- Ted: The G5RV will be slightly more directional toward the broadside on 40 meters than a half wave dipole by a couple of dBs. A parallel 40/75 meter dipole will allow you to achieve low SWR on both b
