[Elecraft] Big antenna - Collins 13 ele Log?

[w6jd at comcast.net]

I've operated 2 meter moonbounce at the Stanford/SRI 150' "Big Dish". The SRI
WARF OTH-R transmit site had two vertical arrays consisting of 18 FTM 
(folded-tilted-monopole) elements looking East and 18 TCI LP elements looking
West equally spaced over a 205m base line. The arrays had a 6deg azimuthal
beamwidth, steerable +/- 32 deg in 4 deg steps. This was a real band opener
on 20 meters!!
