20 kW Solid State FM Transmitter

A solid combination of performance, reliability, ease of service and price define the FM 20S 20kW solid state FM transmitter from Broadcast Electronics. Engineered to the same exacting standards as our complete line of solid state FMs, the FM 20S performs like no other in the industry. An extensive redundancy and protection system has been added that will keep your signal on the air even in the most extreme conditions. Optional standby exciter, IPA’s and power supplies can give you full power standby without having to buy another transmitter. The FM 20S’ large lift off panels provide immediate access to every major assembly for fast and easy repair. In fact, the FM 20S has a lower Mean Time to Repair than any other transmitter in its class.
