[Boatanchors] 75M

[David C. Hallam]

Herman,

I live on a 90'x110' lot that is full of Live Oak trees and have no 
place to put a wire antenna.  The vertical is located in the only open 
patch of ground I have.  It has 10  - 65' radials.  As much as I would 
like to have more/better antennas, I am stuck with this.  At one time I 
tried a 20M 1/4 wave end fed antenna strung over the top of the house.  
It picked up so much noise it was useless, all the wireless routers in 
the neighborhood birdies.
