Another vote for linear antennas: I use a 20 element KLM for 70CM and 14 element Hy-gain for 2 meters. Vertical polarization.
Mounted on an aluminum cross-arm with two U-100 rotors. This has been up for about 12 years, worked on every bird that's been up there, and does a fine job. Total expense: $40. 73, John, K6YK On Tue, 22 Feb 2011 18:56:34 +0000 Jim Jerzycke <kq...@verizon.net> writes: > I agree with Mark 100%. > I've been using my 'terrestrial' M2 antennas on the satellites for > years.
