Need a cheap and quick 2m groundplane antenna? Recently I needed such a thing and laziness and lack of time prevented me from 'doing it myself.' I took a walk to the local Radio Shack and purchased a 20-176 ($14.95) "All band base station monitor antenna." It just so happens that the elements are the correct length for 2m fm work and the antenna, at the end of 50 feet of good RG/8U coax shows an SWR of about 1.2 to 1. The elements are stainless and the hardware is of fair quality. The thing look like it could stand about 100 watts. Ron Hoffmann, WA2EYC/1 Hoffmann@MIT-Marie@MIT-MC

Of course, you could just solder 5 pieces of 1/8" brazing rod into an SO-239 connector and get the same thing for about $1.50. Trim the rods to about 19" and bend the radials down at about a 30 degree angle, and voila! Screw the coax on it, and drop it into the end of the antenna mast. Or use a dual pipe clamp from the hardware store. (Another 75 cents). Bend the radial up and down if the SWR isn't right. If you're going to run over 250 watts, maybe a teflon connector is worth it. So now the whole thing costs $3.00. I'm cheap.
