Sounds like vapor wrap. You need to elongate it (stretch it out about 5-10 times its length) before using it to allow it to vulcanize correctly. It is great stuff. Tom, K5RC/7 -- FAQ on WWW: http://w

Half wave slopers generally model better than low dipoles and much better than inverted vee's (for low angle). I've had very good success with half wave slopers from a 60' tower. Tom, K5RC/7 -- FAQ o
You should have done some research before you started. In the seventies, Dr. Bill Schrader, K2TNO, did similar research on a stealth antenna and published his findings in the Armadillo Press. His ane
The effects are very dramatic. First, the choke tells the RF where the antenna ends and the feeline begins. Second, it minimizes the effect of RF propagating down the coax and back in to your shack.
