Tough rugged construction
The highly dependable diecast aluminum chassis and polycarbonate front panel are resistant to impact.

Powerful 45 W of output power
A powerful 45 W (35 W for the IC-F420) of output power provides reliable long distance communications when you need it.

SmarTrunk II^TM compatible^*
These transceivers allow you to take advantage of all the benefits of SmarTrunk II^TM trunking systems^*. In addition, CTCSS and DTCS encoder/decoder and DTMF, 2-tone and 5-tone encoder are standard. And, 2-tone and 5-tone decoder functions are optionally available to suite a wide variety of signalling requirements.
* Optional UT-105 SmarTrunk II ^TM Logic Board is required; SmarTrunk II^TM is a trademark of SmarTrunk Systems Inc.

Selectable channel spacing
Versions are available that allow wide/narrow switching independently for each channel.

Programmable key assign function
4 switches provide simple operation yet their functions can be changed during programming, providing flexibility to suit your specific needs.
