The Alpha Delta Model ASC Antenna Selector Console desk top coax switch series
brings a new level of versatility and convenience to your station operation.
This series retains all the features and specifications of the precision 4
position DELTA-4B series (see WEB site for DELTA-4B specs, pictures, and info),
including ARC-PLUG(tm) module surge protection, in a desk top console that will
sit on your desk next to your gear. The console does not have to be secured or
bolted down!

The consol features a powder coated steel housing and a solid brass ground
buss, with #10 wire attachment hardware, across the rear of the housing
providing a common ground point for all station equipment and accessories.
"Non-slip" feet are attached for solid stability.

The Model ASC Console is available in addition to the famous DELTA series surge
protected coax switch line. The entire DELTA family features solid mechanical
cavity thru-line micro-strip switching, without the use of problematic
electronics and microprocessors. The series offers low loss constant impedance
performance and best co-channel rejection (typ >60dB) depending on connector
type and freq. Rated at 2kW SSB/CW output. Made in our ISO-9001 certified
facility.

You will note the switch is poistioned in the housing at a 20 degree angle from
the horizontal. If the switch was 90 degrees from horizontal (vertical), the
cables would come out at such an angle that there would be large cable "loops"
and they would tend to try to pull the switch over backwards or move it back
across the desk. A 20 degree angle will provide effective viewing and minimize
or prevent the cables and hand pressure from moving the console.

The solid brass ground bus on the housing can be used to provide a single point
ground for your equipment and accessories. It also provides a ground point for
the operation of the Model D-4 ARC-PLUG (tm) gas tube surge module located in
the switch. A proper ground wire must be attached to the bus for the operation
of the Model D-4 during surge discharges. Proper grounding techniques are
covered in various ARRL and other publication materials.
