Easily amplify your handheld radio to 20-40W (2-6W Input). The AMP‑U25D is a time-saving (and cost saving) alternative to mobile and base radios that simply duplicate the same programming your handheld radio already has.
The AMP-U25D operates from 400-480 MHz and can be used for analog FM, P25 Phase 1, C4FM (System Fusion), NXDN, IDAS, dPMR, MPT1327, DMR, and P25 Phase 2. modes.
The AMP-U25D supports TDMA Modulation used by DMR Radios. It accurately amplifies on the chosen time-slot without timing errors, and without interfering with the other in-use timeslots!
The BTech AMP-25 Series is designed to work with any BaoFeng or BTECH handheld transceivers, but it will also work with any handheld radio that outputs 2 W – 6 W with the appropriate cable. With the included Radio to Amplifier RF Cable, the amplifier will also work with Wouxun transceivers, some TYT transceivers, and some Kenwood transceivers. If the supplied cables do not connect to your radio, you will need to use adaptors or build cables with the appropriate connectors.
Your BTech AMP-25 amplifier does not include an antenna. It is very important to not transmit without an antenna or dummy load connected to the ANT connector on the rear panel of the amplifier.
Transmitting without an antenna or dummy load may cause harm to the radio equipment.
When choosing an antenna, make sure that it is suitable for the bands you plan on transmitting and receiving on. For example, if you plan on transmitting on 145MHz, make sure that the antenna you select has an SWR of 1.5:1 or less on that frequency. Using an antenna with an SWR greater than 1.5:1 could damage the amplifier.
If you plan to use a magnetically-mounted (mag-mount) antennas, ensure that the antenna is grounded to a metal surface, such as a vehicle body. Magnetically-mounted antennas do not operate properly without a good ground.
