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

Does this include the Hy-Gain Model R-3501 Rotator? It's listed in a Hy-gain Amateur catalogue in my possession and was, I imagine, designed to turn the "DX Long John" beams...... the real ones! Chri

Hi, To put it another way, guy wires whose line of action passes through the axis of rotation are not a great deal of use in preventing rotation. Chris Newton was an Englishman ______________________
Sense at last. I note the periodic return to this topic initially with amusement, but eventually with annoyance. There is a prejudice on the reflector against crank-up towers and some of this rubs of
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
I beg to differ. The function of sensible guying is to prevent the tower from reaching its material failure point, or at least delay it. on the contrary, the function of guys IS to make the system st
What Jim actually says is that it makes it weaker! my comment is directed at that statement. Chris _______________________________________________ See: http://www.mscomputer.com for "Self Supporting
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 ________________________
Geert, I am sure that other will be able to comment on the Mosley, but I would certainly be worried about having such a large antenna atop the Versatower in 80 Km/hr winds. As I recall, the most comm

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.
