[TowerTalk] Any thoughts on spider-beams?

[Dave Thompson]

I thought the spiderbeam sold by Vibroplex was a better antenna than most of the other hex beams.  Why?

1.  It is a 3 el beam on 20 and 15 and a 4 el beam on 10.  I guessed that it was a 2 el beam on 17 and 12.

2.  It only requires 4 spreaders not 6 like most hex beams.

I was somewhat surprised that the model supplied by K5VV was lower in gain and the pattern was so poor on 20/15/10 but then again I have not seen other hex beams modeled.
