Sunair GCU-1935 Kilowatt Automatic Antenna Coupler

Sunair GCU-1935 Kilowatt Automatic Antenna Coupler

Part Number:
(EQP) SUN-GCU1935

Product Details:
Well, if you have followed us through  the years you know we don't exaggerate, but when the factory  calls this beauty 1kw continuous, I've got to scratch my head. The roller  inductor should handle 30 amps, the vacuum 75 amps. So, with  a little rewiring.....

Designed to  couple the GSB-900 transceiver and GSL-1900A Linear Amplifier  into a 35' whip and 50' to 150' long wires or works as a line  flattener into unbalanced (coaxial fed) antennas from 1.6 - 30  MHz!

The general design is an "L" network with series input vacuum cap and shunt inductor at the output for short antennas like the whip. For long wires, a fixed doorknob is connected in series with the antenna to form a "T" network. Weighs 85 lbs.
