Call Search. New to Ham Radio? My Profile. You couldn't tell a null from a speech pause. If there was a loud constant background noise, as from a genset or constant RPM propulsion engine, then you could see a consistent "propeller" pattern on the CRT and get a bearing on an HF SSB signal, especially when the guy transmitting paused in his speech and you only had the constant noise modulating the xmtr.

Building Simple Antennas
Forgot Password? When it comes to getting the most enjoyment out of Amateur Radio, there is nothing more important than your antenna system. You can purchase the best ham transceiver on the planet, but if your antenna system is poor, your investment will largely go to waste.
High-frequency antennas transmit radio waves across vast distances and even over mountain ranges using very little energy, making them ideal for military communications. These devices, however, have one big problem: They need to be huge to operate efficiently. Instead of adding more bulk, University of Wisconsin—Madison engineers are working to increase the effective size of antennas by turning the military vehicles that carry them into transmitters—using the structures that support the antennas themselves to help broadcast signals.
