Topband: Fw: The 500 Foot Beverage

[Robin]

that makes a dipole not a beverage. A Beverage MUST be fed at the end.  It 
is a traveling wave antenna, not a conventional coupling antenna like a 
dipole

If you must, build the feedpoint at the end and run the coax cable back 
along the ground under the beverage-  bury it a few inches if you can and 
add a ground post where you make the turn to go to the shack - all an 
attempt to decouple the shield of the coax from being part of the antenna
