Skip navigation Sign in. We used a Palstar AT-500 manual antenna tuner to successfully tune these bands for maximum power transfer from the transceiver. The Watson 80Plus2 designed by G3OJV and sold by Waters and Stanton is a compact antenna measuring 52 feet in length that is designed to cover the 80, 40 and 20 metre bands. Since the antenna is only up from 15 feet to about 35 feet above the ground, it is not a DX antenna on 160 or 75/80. Operation is 80 thru 10 meters. Here is how I managed to get pretty decent results with a homemade antenna. - Uses elevated radials for higher gain. HORIZONTAL LOOP ANTENNA CONSTRUCTION. no real estate. 6-80 Meter HD-FMJ portable HF antenna. Personally, I use a slightly different antenna system for shortwave listening, where the antenna is placed much further away from the house. 4 to 15 GHz operation, meeting FCC 25.
