Masthead Amplifier Kit
Meet the Whyte Masthead WMHA25-4 a high-performance, 4-way UHF masthead amplifier with 25 dB gain and triple filtering for TETRA, 4G and 5G interference.
High Selectivity LTE Rejection
The built-in Class 1, Category D 470–694MHz band-pass filtration helps prevent unwanted interference from 4G/5G LTE and TETRA (Terrestrial Trunked Radio) signals, delivering cleaner and more reliable UHF reception.
