Expand the range of coverage for your handheld or low power base/portable UHF radio with the elegant 100 watts of the RM Italy MUA100 Wideband UHF Amplifier.
RM Italy MUA100 Wideband UHF Amplifier – a compact 100 watt linear amplifier that covers the UHF frequency range from 405 to 480 MHz. This unit is ideally suited for use with low power handheld transceivers with an input drive range from 0.1 to 5 watts. The MUA100 features include a high SWR protection circuit, a heatsink mounted fan for temperature control and an automatic RF sense relay. Even though a ground on transmit PTT cable to the provided relay phono connector is not required, it is recommended for SSB operations.
The MUA100 power supply requirement is 12 to 16 Vdc to maximum continuous input current of 20A at full output. Unit dimensions are 190mm (w) x 82mm (h) x 190 mm (d) and weight 1.5 kg. Input and Output RF connectors are N-Type Female.
THIS UNIT WILL ONLY BE SOLD TO QUALIFIED AMATEUR RADIO OPERATORS AND MUST ONLY TRANSMIT ON AMATEUR FREQUENCIES. THE PURCHASER MUST PROVIDE PROOF OF THEIR AMATEUR RADIO QUALIFICATION. IF YOU DON'T HAVE AN AMATEUR RADIO (HAM) LICENCE PLEASE DON'T PURCHASE OTHERWISE WE WILL REFUND YOUR PURCHASE.

Please Read Before Using:
- Do not use outside of the specified frequency ranges as damage may occur.
- Care needs to be taken that the antenna you are connecting to is in good condition and the VSWR is less than 1.5:1 on the frequency you are transmitting on.
- For higher power amplifiers (100+ watts) we recommend a single band antenna tuned to the frequency you are transmitting on.
- Never use an amplifier to attempt to compensate for a poorly tuned, high SWR antenna, for poor quality coaxial cable or connectors.
- We strongly recommend not using a power amplifiers with an indoor or loft antenna.
- Check the transmit power immunity of your vehicle if vehicle mounting as this may damage the electronics and/or disable your vehicle or functions of your vehicle.
- Be certain that the supply current from your power supply is ample for the peak current draw of the amplifier otherwise damage to the amplifier may occur.
- Be very careful when operating at high power and keep well clear of the transmitting antenna.
- Always check your antenna and feedline performance with an SWR meter on low power before increasing power to maximum.
- Do not overdrive the RF input of the amplifier.
- Do not operate the amplifier without a 50 ohm antenna or overrated dummy load connected to the antenna output.
- Do not operate your amplifier in hazardous environments - ie service stations, mines, etc
- Regularly or continuously test your antenna and feed line SWR for unexpected performance issues.
- Disconnect the antenna if lightning or storm activity is occurring nearby.
- Do not touch the antenna or exposed antenna connections when transmitting.
- Stop transmitting immediately if a fault appears.
