HIGH POWER OUTPUT (65 W)
Even with its compact size, the TM-281A delivers up to 65 watts – the sort of RF power you want in the wilderness – with a choice of High/Low output. A hand microphone is also supplied as standard.
Whatever the mission, wherever you go, KENWOOD’s TM-281A is a radio you can count on. This compact transceiver delivers powerful mobile performance and such advanced features as multiple scan functions and memory names. High-quality audio is assured by the large speaker. Naturally, MIL-STD compliant toughness ensures rugged reliability. And operating ease is second to none: illuminated keys and a large LCD with adjustable backlighting make for user-friendly operation day or night.
