I have been using the KLM 2m (14 el) and 440 (18 el) circular pol. antennas
since several years with no problem. My setup is a 4 m tower on top
of a 8 floor condo building. They are mounted on a horizontal fiber
boom quite thick,almost the maximum diameter that fits the Yaesu elevation
rotor. I have wired the pol switch on both antennas but seldom use it,
anyway I didnt noticed any problem with them and they seem to to change
the polarization.
I have operated Oscar 13, MIR phone and packet, FO-29 and Oscar 10 with
this set up.
I see only a mechanical problem on my fiber boom, with time it bents
and seems that can brake at any time, but its there...
