I have a Roadtrek (small Chevy van converted to a mini-motorhome) which has
a fiberglass upper roof. Wanting to set up good ground to air communications ability on 123.5 and 123.3 with a Tait mobile radio in the vehicle. The problem is establishing a ground plane with the fiberglass roof. Other than a magnetic mount antenna on the metal hood....any suggestions? Wouldn't mind a fiberglass whip type set-up if the performance gains justified it, but I would like it to be functional while driving....also don't know how to establish the ground plane. Appreciate any advice. Thanks! J4 |

You may well do better with a 5/8 one for lots of reasons. Your need there will be a secure mount location to the longer whip. Darryl |

Darryl,
I disagree with you on this one. A 5/8 DOES require a ground plane. However, a 1/2 wave length doesn't.

Doh what a silly slip, thanks for catching that. But you can get base 5/8 antennas that include the round plane stubs like Paul mentioned here.

Darryl In your defense Darryl I've always had better trans/receive when I mount a 5/8 wave antenna on a 40' stainless steel tanker than I do on a fiberglass roof Kenworth tractor. 10-4 |

Darryl Wayne, Wouldn't this have been a good place to link to your 'coax dipole' antenna? (I was looking for it and got side-tracked [squirrel!] looking at Scheder stuff) |

Hi John,
I sell a nice 5/8 wave antenna that includes 4 radial rods at the base which act as the ground plane. You can see details he http://www.cumulus-soaring.com/larsen.htm#Larsen-BS-5-8 Best Regards, Paul Remde Cumulus Soaring, Inc. "John Bojack" wrote in message ...
