The Yaesu FC-757AT was designed to connect to several Yaesu transceivers but can be used with any radio by simply providing 12 VDC (info on how to do so is included). The frequency range of this tuner is: 1.8-2, 3.5-4, 7-7.5, 10-10.5, 14-14.5, 18-18.5, 21-21.5, 24.5-25 and 28-29.9 MHz, with maximum RF power is 150 watts. The meter power ranges are 15 and 150 watts. Two antenna jacks are provided and provisions exist to control an external optional antenna switch. Includes a built-in dummy load.
I was told this tuner was never actually put in service, but of course no way to verify that. It does look like new, and includes the mating cable, manual, and original box and packaging. It'd be hard to find one in nicer shape!
Price is $250 which includes shipping in the US.
