Call 0345 2300 599The RM MUA100 is a compact 12V wideband linear amplifier for the UHF band, covering 405 to 480 MHz. It is designed to boost low power portable and mobile transceivers, making it a practical option when you want more effective UHF coverage from a handheld or QRP style setup.
The MUA100 supports FM, SSB and CW, and includes automatic RTX switching so it can change between transmit and receive without a separate PTT line. For SSB use, a dedicated PTT input is also provided and is recommended for best operation. The amplifier includes protection against excessive antenna SWR to help reduce the risk of damage from a poor match, and it is fitted with a cooling fan for more reliable running under load.
