Do I need a license to use the MXT105?

Yes. It transmits on GMRS frequencies, which require an FCC GMRS license in the US. The license covers your immediate family.

How does it compare with the MXT115 or MXT275?

Those models put out more power and add features like weather channels and repeater access. The MXT105 is smaller and simpler, with shorter realistic range.

Can it reach other Midland handhelds?

Yes, as long as they are on the same GMRS channel and privacy code. Handhelds will hear it, but range depends on terrain and antenna placement.

Expect the radio unit, a microphone, a power cable and mounting hardware. Check the listing for the exact included antenna and bracket.

Is it good for off-road convoys?

It works for short spacing between vehicles. For long spreads or hilly terrain, a higher-power mobile radio with an external antenna is the safer choice.
