I remember drooling over the pictures of these antennas as a young kid, but 
that was a long time ago. The elements did not go through the boom and 
these antennas, 204B, 205B, 403B, 106B, 155B looked as though they were 
built to a standard rather than to a price. In 1967 the 205B cost $595 and 
the 403B $1150. (403B 3el40m on a 46foot boom)

I seem to recall ads in QST showing a Christmas Tree (on an RP-75?) at 
K7UGA, but perhaps old age has addled my memory. Hy-Gain made a suitable 
rotator, the RBX-5 which subsequently became the R-3501 again, if my memory 
serves. Whichever, not the sort of thing to put in Rohn 25......
