Close attention should be made to the names and calls involved, and especially in further use of this newsgroup. Regards, JS |

... Where are instructions on building them? Buck: You just have to go on the scanty details presented in the news releases, I can't even find a picture of the darn thing. However, I threw together a 1/2 wave - 6.5 ft. (includes 12 inch adjustable whip and disc top hat at base of whip.) "Plano Helix Coil" constructed by drilling two sets of holes on opposing sides of 1.125 pvc pipe, wire is then "laced" through these holes - forming a series of "hair pin loops" running the length of the pvc pipe. This gives an apparent equal radiated power on a sensitive homebrew FSM located ~3 wavelengths away as compared to a 1/4 wave 102 inch whip w/loading coil on 10 meters, both mounted as mobile antennas on the auto. I have no idea how close the design of this antenna matches Mr. Vincents design ... The antenna is worth playing with, definitely! I too would like more details on Mr. Vincents designs ...
