[TowerTalk] Reverse Fed Towers

[Wayne Kline]

HI William
 
 I have use the N4NG  reverse feed system for years .  I lost my 3 element 40 meter beam @ 108'   . this was the top loading. I replaced it with a Chushcraft XM 240  with it's insulated elements I no longer had any top loading  other then the boom  and could not get the radials to  low enough ( tripping danger) to work.
The formulas given in the original article     were a good starting point..  
I never had a model was just using the trim, move and,measure approach .  Ended up with 8 radials cut and tuned for 1.825 MHZ  @ 36 '  on a 105' tower and antenna @ 108
