MicroMobile Two Way Radio is rated 4.8 out of 5 by 155.
Rated 5 out of 5 by from Jeep Wrangler Rubicon MXT400 & MXTA26 WHIP ANTENNA I read the reviews before purchasing this radio and antenna. The radio and antenna certainly live up to the hype. It is small, light weight, and well built. The radio was engineered with inline fuses making it easy to work on should you blow one and also easy to add to a pillar switch pod. The repeater channels offer great range while wheeling or hunting. The MXT400 works well with hand held radios who are spotting while wheeling or communicating with blockers during pheasant hunting season. Easy to install, easy to use, and offers good communication clarity Jeep to Jeep or Jeep to handheld.

Rated 5 out of 5 by from I just installed this radio in my truck. Very impressive radio. The range talking to my wife who was using a Garmin Rino inside the house and me on the MXT400 on high power was about 7 miles in an urban setting. One of the reviews stated privacy codes did not work. I found that they do indeed work. Follow the manual on setting the codes. I suspect people are using the DCS codes vs the CTCSS codes where you look at the manual and cross reference the privacy code to the frequency you must select under CTCSS. Works perfect.

Rated 2 out of 5 by from I have2 of these. I own 2 of these radios, they work great for simplex, However I just read on another site these radios are Narrow Band only! no problem talking simplex with the same type radios, But, not good with repeaters! Most gmrs repeaters out there are wide band ( GMRS is Wide Band not narrow), so you have some problems there! If these radios are in fact narrow band only, It would have been nive for Midland to have stated that! I was about to order a 1500.00 repeater, lucky for me I read that post about narrow band. Other wise, great radios,simple, and work well, but Midland needs to makesome changes

Rated 5 out of 5 by from One of the few legal (FCC part 95) radios. I received this radio 2 weeks ago. It is temporally using a Tram 1170 UHF mag mount antenna. The SWR is at 1.1 to 1. (Previously tuned to GMRS frequencies. With the antenna centered on my roof. Ford f250. I was using it on Long Beach Wa. On low power I was consistently hitting a repeater in Astoria Or. I had tried it on medium pwr, 22 watts, but that was not necessary as long as I was on the the beach. This is a distance of approximately 20+ miles. I do not know the height of the repeater in Astoria. Hope this helps. Keith T.

Rated 5 out of 5 by from 2010 Subaru Forester I was able to install the Midland MXT400 in my 2010 Subaru Forester. Because of the way I wanted to conceal the radio, I did have to do some modifications to the console storage located in front of the manual shifter. I had to remove many pieces to to go the parts, but the overall look is exactly what I wanted. I could not be any happier with the way the install turned out. I also used the low profile 6db gain antenna and mounted it to the front hood and ran both the power (direct to battery) and antenna cable through separate firewall locations.

Rated 5 out of 5 by from Amazing Radio So far so good! I bought this radio for off road use but have not had the chance to use it other than testing in the city. Keep in mind when buying these radios that they don't all come with and Antenna and cable. Great product and very fast accurate shipping. Get your GRMS licensee "Its easy to do" and buy yourself a Midland Radio. This blows CB out of the water and is a big improvement over FRS as far as range and clarity is concerned. My 1 complaint is I wish they would include the Low power FRS channels on these radios so that you can talk down to FRS users as not everyone on the trail has GRMS capabilities.

Rated 5 out of 5 by from MXT400 - Awesome Radio I bought this because several other members of our Jeep club have GMRS radios. I wanted a radio that had high watts, because there are times when we are overlanding that I want that extra power for further range. I have it installed in the Jeep along the right side of the center console and liked the quality and reliability of it that I purchased a Midland CB to communicate with the other members that don't have GMRS.

Rated 4 out of 5 by from great backup commo I bought this radio and installed it overhead in my Rubi. I tested it to 11mi here in Montana on hilly terrain from outside the city to another vehicle in my driveway. It was crystal clear and I am sure that it would transmit much farther but I was about to start up a mountain and that added elevation would not be a fair test. I have tried it with the T71VP3 and achieved 5+mi in town between MXT400 to handheld. It needs the ability to have dual tones for repeaters, be ruggedized, and should most of all be ip68 waterproof. rated. That keeps it from a 5star rating overall. As a simple ,strong, and effective backup communication device it gets 5stars.

Can the MXT400 be powered via DC outlet?

Asked by: Flyangler133
No, unfortunately it needs more power to operate than the DC outlet gives out. It needs to be directly hardwired into the vehicle/ power source.

Can I use the ext speaker port to connect to the radio in my Jeep so the sound comes out the car speakers?

Asked by: Terry in CO
The MXT400 provides a rear-panel jack for connection of an optional external speaker (sold separately). When selecting an external speaker, ensure the speaker has 8-ohm impedance and is rated for 4.0 watts. NOTE: When an external speaker is connected, the radio’s internal speaker is automatically disabled.

does the mtx400 transmit at full power or just 5w on frs channels like channel 1? i see the max allowable xmt power is 5w for 1-7 and 0.5w on 8-14.

After buying 2 of these I just read they are narrow band only!  That really sucks if true, because almost all repeaters in use are wide band( gmrs IS Still Wide Band)! So is this true?

Asked by: Jeff Rooke
Hello! The repeater channels on the MXT400 (only) are wide band compatible by default. The MXT400 PC software used with a DBR1 programming cable, will allow further wideband channel configuration. Repeaters run both wide and narrow band, with wide band being more popular do to its historical use. You should check on the repeaters in your area to see if they are wide or narrow band. Some are switching over to narrow band. Despite the bandwidth of the repeater, the narrow band radio is compatible with a wide band repeater. Using a  narrow band radio on a wide band repeater might cause some diminished audio.
