[TowerTalk] Effect of tower on antenna performance

[Cox, Norman R.]

Dear Group,

    I don't think I've ever seen any information on how a tower effects an HF beam's tuning and pattern.  I've never simulated the effect or made any measurements myself.  Can anyone tell me what generally to expect if the mast is only one or two feet above the tower?  Would a mast 5 or 6 feet higher be any better?

Thanks!
