Trimming 2m 5/8 wave antenna for 156 mhz ???
James wrote:
Hello ! I just bought a 2m Hamstick antenna at the Orlando Hamfest, the model 9100. I would like to trim this antenna for 156 mhz, for marine use on my boat. Can someone tell me "about" how much I should shorten the whip to achieve this ? Remember, this is the 5/8 wave antenna with a loaded base. Thank you very much !! 73 de Jim K4PYT IRRC the Hamstick is a quarter wave antenna and requires a counterpoise to operate correctly. You would be better off getting a marine 1/2 wave antenna for you boat as most fiberglass boats do not have enough metal to provide the counterpoise. Dave WD9BDZ |
