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

I'm not an engineer but the analysis is relatively straightforward. It's easy to 'simplify' the structure and see what is actually happening in high winds. (As a mathematician I'm more interested in

Excuse me, the tower is rated for 120lb (sic) headload and you want to apply 590 lb, albeit opposing the 120lb on the antenna? Do you think this is a sensible strategy? Chris ________________________

If you really mean the original Hygain Long John monobanders (c. late 1960s) then the MFJ versions, and the later Hygain ones for that matter, are a joke. The originals were very rugged indeed! Chris

Hi Ted, I was comparing both the later Hygain versions and, presumably, the similar MFJ variants with the original Hygain Long Johns. Those original Hygain Long Johns were nothing like the 205BA etc.
