While loop antennas generally have less gain than wire antennas, they do offer directionality and low noise reception. Rotating the loop can help eliminate interference or noise. The loop rotates and tilts to give deep nulls so you can eliminate local interference. It also may allow you to null out a station and listen to another one on the same frequency.
Only loops that tilt can do this. Deep nulls permit the listener to null out nearby stations to permit DX reception. The loop can also facilitate direction finding.
The new improved, Palomar LA-1 is the amplifier-mounting base in which the various loops plug into. Controls include Tune and On-Off.7 x 6 x 2 inches. Output is 50-75 ohms to a standard SO-239.
The LA-1 will operate for a long time on a single 9 Volt clip-on battery since it draws only 3 mA. Each loop element is designed to cover a certain portion of the frequency spectrum. The loops rotate 360° in azimuth and tilt ± 90° in elevation. This item is in the category "Consumer Electronics\Radio Communication\Antennas\Ham, Amateur Radio Antennas".
