Portable End-Fed 160-10 Meters Dipole Antenna
A friend of a friend has this stealthy antenna going up the side of his building and over the roof. He says that he gets a great SWR on all bands from 160 meters all the way through 6 meters, even though it only advertises up to 10 meters. He runs a counterpoise of .1 wavelength in his apartment, about 50 feet. He uses an RF choke to further reduce common mode current. He says that it works wonderfully. I wouldn’t know anything about it though.
