mounted on the mast. Relays in the switching unit route signals from the appropriate
combination of loops in response to commands received from the controller. A single
delay line also connects to the switching unit to provide the necessary true-time-delay so
that signals can be properly combined to achieve the desired directive pattern. The
switching unit has a socketed dual stage preamplifier that provides a buffered and
matched load for the combiner and boosts the summed signals before they are sent to the
controller.
The AS-SAL-12 Mark II should provide a directional pattern up to 28 MHz. The AS-
SAL-20 Mark II should provide a directional pattern up to 14 MHz, and the AS-SAL-30
Mark II up to 7 MHz.

Wideband operation without need for adjustment that is great for SDR, Skimmers
and military
•
Ease of Construction, and quick deployment, DX-peditions, military, seasonal
take down is easy
•
No RF ground at the antenna required
•
Modular design – easy to replace parts
•
