I installed one of these a few months ago, in place of my 20-turn Wimo
helix. Both are nice antennas, but I'll give the edge to the M2 yagi
(more gain and it mounts balanced on the elevation boom). I have
mine with vertical polarity. Since AO-51 is linear on L-band, it
shouldn't matter--but putting that little antenna horizontal in line
with my metal boom didn't seem to make much sense....
