[TowerTalk] A3WS vs WARC7 Yagi

[n4kg@juno.com]

The main question is how much a little more gain on 30M
worth to you.  I would expect similar performance on 17
and only slightly more gain on 12 (1 dB).  The main 
disadvantage to trapped beams is bandwidth.  This is
not a problem on the narrow WARC bands.  My guess
is that the A3WS plays like a full size 2L Yagi.

I have worked over 300 countries on each of the WARC 
bands using only dipole antennas.  A rotary dipole at 
80 to 100 ft is a real KILLER on 30M.  Even 60 ft plays
well.
