  • Due to my move to Bismarck North Dakota (begining of October 15), most of my antennas are still packed. I installed two of them: 80-10 meter B&W Broadband Folded Dipole in a temporary location with the feed point at about 18 feet and the Comet 144, 440 and 1.2 GHz verticle at 20 feet so I can be on-the-air this winter. In the spring, I'll install my tower and the rest of the HF, VHF and UHF antennas. This web site shall be updated as things change.
