[TowerTalk] 45g Tower

[Gene Fuller]

100 feet, if possible, is nice. Great for 40, for 80m halfwave slopers and 
160m quarterwave slopers. Pretty good most of the time on 20, especially for 
longer paths. Perhaps a little high at times on 15 and 10. A tribander 
pointed at the Carib and S A strapped to the side of the tower at 40-50 
feet, or better yet on a side gate to also allow covering Eu is a great 
supplement.
