VHF-FM Antenna Made From 450-Ohm
Great first time J-pole project. Covers
most of the basics.
This small and thin design also makes it good

the ground. And, remember height determines range at 2 meters.
The gain for a 1/2 wave J-pole is approxmitately 2.4 dbi over a 1/4 wave
whip. Not bad for only a few bucks.
