U20338 Used TE Systems 4412G UHF 100W Linear Amplifier 15-20 Watts in Max

U20338 Used TE Systems 4412G UHF 100W Linear Amplifier

Overall Condition: Used, excellent physical condition overall! Shows standard wear from normal use on the case, with clean gold-anodized faceplate graphics, switches, and heatsink fins. Hardware Note: One rubber foot is missing from the bottom of the unit chassis. Rear tag is clearly legible (Model #4412G, Serial #B4345, F: 430-450 MHz). Comes complete with fused DC power cable assembly and the original TE Systems operating and service manual.

The TE Systems 4412G is a high-power, commercial-grade UHF 70cm (420–450 MHz) linear RF power amplifier built in the USA. Delivering up to 100 Watts RF output power across FM, SSB, and CW modes, it features a built-in low-noise GaAsFET receive pre-amplifier to boost weak incoming signals.

Designed for extreme reliability in mobile or base station environments, the 4412G includes automatic RF-sensing T/R switching, adjustable SSB hang-time delay, thermal overload protection, and high-VSWR protection.
