Any reason why, using identical coax lengths, you could not transform the impedance to 100 ohms and then use a T connector to sum both antenna signals and achieve 50 ohms to the radio? I know Transmit power will be 3 dB down at either antenna but is there any reason it will not work? Any antenna gurus out there?

At any given moment, you only have 1 chance in 90 that you will have matching polarization. So, if you plan to use the antenna for other than Satellites, set your polarization for that purpose (V for FM or H for SSB/CW). My plan is to install 2 Elk antennas, one V and one H. Then, have a relay that I can switch between the two and choose the best downlink signal at any given moment. This arrangement will also give me optimum flexibility for terrestrial operation on 2 & 440. Now, where can I find a relay to do that function????? 73/GL, Bob K8BL --- On Tue, 4/16/13, Lee Maisel <mai...@lobo.net> wrote: From: Lee Maisel <mai...@lobo.net> Subject: [amsat-bb] Re: Mount an Arrow on rotator with 2m vertical or horizontal To: "Don Hoover (WS4E)" <w...@arrl.net> Cc: amsat-bb@amsat.org Date: Tuesday, April 16, 2013, 12:24 AM Hi Don, I have mine mounted with 2m elements horizontal, because that's how it seems I used it most when it was handheld.
