The MobileMark LTM301/LTM302 vehicle antenna is an all-in-one system for improving cellular signals when traveling. It is designed for use with buses, ambulances, trucks and other commercial and municipal vehicles so they can be remotely managed effectively. It contains two identical elements for use with modern LTE multiple input, multiple output (MiMo) modems. Adding the LTM antenna to your vehicle fleet can improve wireless connectivity so you will be able to track location, transfer data and perform other important functions in more areas.

Each low-profile white LTM antenna contains two identical cellular antennas. The MobileMark 2-in-1 LTM Antenna has a field-tested design that meets industrial and military standards for shock resistance and vibration resistance. The cables are 15 feet long to reach the vehicle’s networking equipment and can be bundled and stored easily if not in use.

Using a multi-band vehicle antenna can deliver better data performance for your business while taking up less space than individual antennas. The LTM302 requires a metal ground plane is attached to a vehicle by drilling a small hole in the roof for the cables and using mounting screws to secure it in place. It works in temperatures ranging from -40 to 176 degrees Fahrenheit and has a case that resists UV fading. Adding it to your fleet will assist you in making sure that both vehicles and drivers are acting as they should. Contact our support team to learn more about other MobileMark thru-roof antenna options.

This antenna requires that you drill a hole in the top of your car/RV/bus to install it, and a minimum 8x8" metal ground plane is recommended. If your vehicle's roof is fiberglass or another material, copper or aluminum tape in an X shape can be substituted as a ground plane. A ground plane is not required but will improve performance.

The antenna helps maintain a steady signal in areas that would be dead zones.

An update from my 2017 review, and an upgrade to 5 stars. This antenna has covered a solid 95% + of our cellular data feed since we installed it. The other 5% of the time, we use a cellular amp with different antenna. A solid performer, and product has held up well. Like it so much, I'm about to purchase a new unit from Mobile Mark for another application. And when you consider the quilt of the build, and the technology and design has proven to work well - I retract my 2017 comment on price. Thanks MobileMark, and 5G STORE.

I have 2 MobileMark Mag Mount antennas, and they work great.

The MLTM301 seems to be a solid built unit that feels beefy and with good materials and workmanship of assembly. Wire harness an fittings are likewise of good quality material. The unit has had limited usage so far, but I did take our RV to a place we know well that has marginal ATT coverage. We had over double, say 120% more, download speeds improvement with our Unite Explore 815 connected tot he MobileMark. Please with that first test showing the abilities of the MIMO MobilMarks ability to pull in a more useable data signal. On build quality and our limited usage so far, 5 stars. I feel the price is a bit high for such a unit, and so overall rated it 4 stars above. (Note: GPS wire is coiled, and have no immediate plans to use that feature. But this sure could be a factor for someone else that wants GPS signal.)
