This seems awfully expensive. Array Solutions doesn't spend that much for the relays inside their Six Pak.
Top Ten devices doesn't spend that much for the SPDT relay inside their A/B station selector. That unit goes for $77, and that includes a nice box and the connectors. The T/R switch within my Ameritron AL-1200 doesn't cost that much. Wouldn't a sealed or frame relay do the job? 600 watts into a 50 ohm resistive load is 12 Amps. 20A DPDT frame relays can be acquired for a lot less than a coaxial relay. SPST relays cost even less. KK1L uses relays that are advertised at about $3.16 each in his 2 x 6 antenna switch. Is it necessary to operate concurrently on HF and 6 meters? Wouldn't a couple of SPST relays suffice for this application? 100 watts into 50 ohms is 2A. You can use a much smaller relay on the 100 watt exciter to amplifier side. I'd use 5A relay. 73 de Dick, K6KR > That can be accomplished with three DPDT coaxial relays such as the CX800M ($159/ea from http://www.rfparts.com/coaxial.html ) $477 total > It can be done with two coaxial transfer switches but probably cost more (KC 1420-820 from http://www.surplussales.com/Relays/rfcoaxialrelays/rfcoax_n.html are $275/ea.
