In March of 2003 I decided that I wanted an outdoor antenna system for 2-meters and 70 cm. I was involved in the Arizona Near Space Research balloon launches, and setting up an echolink link at my house.
I found an article in one of my old Handbooks that described using copper pipe to build a 2-meter J Pole Antenna. By following the article, it was simple to create an effective antenna for two meters. For 70 cm, I simply made a 1/4 wave ground plane antenna.
After cutting all of the parts to the required length, taking into account how far they slide into the connectors, I cleaned the joints, then soldered it all together with flux and plumbing solder.
After soldering everything together, including the sliding matching clamp, I built a really simple 1/4 wave groundplane antenna for 450 mhz. These were both mounted on a piece of 1-inch copper pipe, which was hoisted to the top part of the tower, just below my cushcraft A3 beam. It was a warm day, and I got a little exhausted while working up there, so I came down, and my brother Roger, ka0jti, finished clamping everything in place for me. You can see the 70-cm antenna on the right.
And here is the final result. The 70-cm antenna does amazingly well, easily reaching to my workplace 13 miles away, and covering most of the East Valley without a problem. It's amazing what 40 feet of elevation will do for you!
And here is a closeup for the VHF/UHF antennas.
