SAL-30

SAL_30 Shared Apex Loop Array: A Wideband Directional Receiving Antenna for 500 KHz - 30 MHz without mast (must be purchased separately)

Effective communication on the LW, MW, and SW bands requires more than just a careful ear. You need the right gear to navigate through the jungle of interference that can be as close as your computer, or as distant as a thunderstorm on the other side of the globe. Interference, though isn't just a challenge for DX'ers - it's a challenge for net operators, rag chewers and county hunters too, military operations - in other words, it is a challenge to all of us!

We have developed a new type of receiving antenna that delivers exceptional directivity in a small package and is useable over a wide range of frequencies without need for adjustment. This new antenna is called the Shared Apex Loop Array antenna and it opens the door to a new class of compact, high performance, wideband receiving antennas developed for both amateur and professional users. 

OBS! No mast is included in this version as it would be costly to ship.

The antenna operates on the true-time-delay principle rather than the more traditional phased array methods. This method of operation enables outstanding bandwidth. For example, a 18 foot tall, 18 foot radius array can provide outstanding front-to-side and good front-to-back performance for continuous frequency coverage below 500 KHz to 16 MHz with good sensitivity above 1.8 MHz! A 10 foot tall, ten foot radius array provides continuous frequency coverage between 500 KHz to 22 MHz with good sensitivity above 5 MHz.

The patented and additional patent pending designs provides the following benefits:
