[TowerTalk] Effect of tower on antenna performance

[Cox, Norman R.]

  Ok.  I guess a little more stick (mast) wouldn't change the pattern all that much.  Thanks for your response.

Assuming your tower is vertical, your Yagi is horizontally polarized
and the diameter of the tower is much less than 1/4 wave, the tower
will have negligible effect on the Yagi's tuning and pattern.

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?
