                I'll be limited by the location spots available, but I
                have one more question:<br clear="none">
                <br clear="none">
              </div>
              I'm intending to have the FTM-350 running APRS, and the

            </div>
            I know I should mount those antennas as far apart as
            possible, but given the 50W output of each, what is the
            minimum separation for the safety of the radios? <br clear="none">
            <br clear="none">

          It's almost certain to end up with the 7000 V/U on the front
          mount point, FTM-350 on the middle, and the 7000 HF antenna on
          the back. <br clear="none">
          <br clear="none">
        </div>
        I know the APRS will still punch holes in my reception on the
        7000 VHF, but I'm hoping to minimize that. My main concern is
        not having the front ends damaged by the RF from the other
