One unit with built in power supply, automatic antenna tuner capable of matching up to 5:1 SWR on HF and 2.5:1 SWR on 6 meters, watt meter, SWR meter, two transceiver inputs, four antenna outputs.

Will not include power plug. As-is, $4500 includes shipping and insurance to ConUS only. Postal money order is best, but....
