If you want to talk to the guy in the next county on HF, of course. We have all experimented with antennas. At one time or oilier we played with dipoles, verticals, quadst vagis, and variations of wire antennas, All for the desire of a low-angle signal, which will help us snag DX stations, There have been numerous articles and books on antennas, making us very familiar with the above antenna names. But have you ever heard of the Australian District Antenna, or the Russian Zenith Radiation,n or...

Guessless Beam Pointing
This has been around for years, but for you newcomers It would be hard not to notice the improving conditions on our HI bands. During the next few years, contacts around the world will be easy to make and signal strengths will be very high. Working DX will be possible with barefoot rigs and simple antennas such as dipoles and verticals. Abeam antenna can do a much better job however. For example. a three element vagi beam can show about an 8 dB i ain over a l 2 wave dipoie mounted at the same...

For some reason, I decided that QRP was going to be the spark this time around, and determined that when I got hack on HF. it would...
