WWCR Shortwave
wwcr has four 100,000 watt, state of the art, transmitters which serve the world on 10 different broadcasting channels

CB modified antenna for the 12m band CB modified antenna for the 12m a quarter of a wave

Antenna Half Sloper Multiband 1.8, 3.5, 7, 14, 21, 28 MHz I made about 25,000 QSOs on it mainly in international contests - in 1.8, 3.5, 7, 14, 21, 28 MHz bands. The antenna also works effectively in WARC bands

A Three Element Hex Beam for 50 MHz This is a hex beam for six meters.It has three elements with a turning radius of 54 inches

DHD Double Half Delta This is a dhd double half delta in theory it should return a low signal but with a good s - n ratio roughly like a beverage

30 meter full quarter wave vertical A view of the antenna and stand from a few feet away. You can't see the radials but they are there. There are four of them spaced 90 degrees apart and about a 10 to 15 degree slope. The antenna has about a 1.2-1 SWR on 30 meters. Notice the trees in the background. Does it look like the wind is blowing? It is as is usually the case out here
