TM-281A VHF Transceiver | Radio Base Station VHF Transceiver KENWOOD TM-281A
Bergaransi RESMI.
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.
RUGGED,
COMPACT CONSTRUCTION
The
TM-281A is tough enough for off-road assignments: it meets the strict U.S.
Department of Defense MIL-STD 810 C, D, E, F & G environmental standards
for vibration and shock. Installation is easy due to its compact dimensions:
160 (W) x 43 (H) x 126 (D)* m
* Total depth of 170.5 mm with protrusion
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.
ALPHANUMERIC LCD AND
ILLUMINATED KEYPAD
The vivid amber LCD display comes with a 32-step brightness control to suit any ambient light conditions. It displays up to 6 large alphanumeric characters. The front panel keypads are also illuminated for ease of use.
The large oval speaker (58 x 35 mm) mounted in
the front ensures every message is heard loud and clear.
MEMORY NAME FUNCTION
Up to 100 memory channels can be identified with
a maximum of 6 alphanumeric characters each. (200 channels are available if the
memory name function is not used.)
200 MEMORY CHANNELS
PLUS 1 CALL-CHANNEL
Each of the memory channels can be used to store
transmit and receive frequencies independently. Additionally, memory data can
be edited and stored on a computer*.
*Requires USB Programming Cable KPG-46U, and Memory Control Software MCP-1A (Ver.3.0 or later); consult your local dealer for details on purchasing these options.
MULTIPLE SCAN FUNCTIONS
Included as standard are VFO scan, memory scan,
call scan, Tone/CTCSS scan and DCS scan – with TO (Time-operated), CO
