Hello, Thanks for the help, I was told by a couple people, don't bother with the poly's, as it's so close of a hit if the radio is 2 feet away it will get nailed also. But, hey they are only $50 or less and not a lot of loss. I'm not going to risk the AP's...
Take a look at my site http://www.lancastertowers.com and look at the tower on the right hand side... I'm considering mounting to the top 10% but not right at the top possibly. Any thoughts on this? Thanks again for your input, and you sure moved a long way to the Bahama's!
