http://www.astronantennas.com/polarization.html On line-of-sight (LOS) paths, it is most important that the polarization of the antennas at both ends of the path use the same polarization. In a linearly polarized system, a misalignment of polarization of 45 degrees will degrade the signal up to 3 dB and if misaligned 90 degrees the attenuation can be 20 dB or more. -- The Anon Keyboard I doubt, therefore I might be Someone wrote "your best bet is probably a small beam, regardless of polarization issues.

Replied However, a yagi can be rotated 90 deg to have vertical polarization thereby avoiding the cross polarization attenuation which can be significant. Just be careful of interaction between the yagi elements and the mast. AND A quad can be fed to have vertical polarization -- The Anon Keyboard I doubt, therefore I might be "Bob Miller" wrote in message ...

Depends on how high the repeater antenna is and how much power you're running -- to hit a repeater at that distance your best bet is probably a small beam, regardless of polarization issues. A beam would also be your best bet for general 6 meter work. Six meter beams aren't all that expensive -- if you really want to homebrew one, do a google search. bob k5qwg Have you had experience and can you recommend a good one..!!! THX in advance Tony |
