Overview
The Midland MXTA51 is the practical antenna kit for an MXT575 vehicle setup. It is a direct-link product in this catalog because the cleanest path is Midland's own listing, and the role is narrow: get the antenna outside the vehicle without turning the install into a radio project.
Pros & Cons
Pros
- Official Midland replacement kit — designed specifically for MXT500 and MXT575
- Strong 3.5-inch magnetic base with rubber boot stays put on roof or hood
- 6-meter RG-58A/U coax cable gives plenty of routing flexibility in a van or RV
- 2.1dB unity gain antenna restores factory-spec range after trail damage
- Includes metallic plate (MXTA38) for non-ferrous roof surfaces
Cons
- 2.1dB gain is modest — serious operators may want the MXAT01VP (7.5dB, $195) for max range
- Magnetic mount is not a permanent install; may shift at highway speeds without MXATMT1 bracket
- ASIN unverifiable via Amazon (bot-walled) — sold primarily through Midland direct and specialty radio retailers

Why The Antenna Matters
A GMRS mobile radio is only as useful as the antenna system attached to it. Put a strong radio behind vehicle glass with a poor antenna path and the real-world range shrinks quickly. Move the antenna to a better roof or hood position and the same radio has a much cleaner shot.
The MXTA51 is a modest-gain magnetic NMO kit, not a maximum-range tower solution. That is exactly why it fits an RV or van kit: simple, compatible, reversible, and easy to understand.
Install Fit
This is for vehicles with a practical magnetic-mount location and a cable route that will not pinch, leak, or rub through. It is not for apartment windows, concrete buildings, or handheld radios.
Plan the cable path before buying. The best antenna is the one you actually route cleanly and leave in place, not the bigger one that stays in a box because the install is annoying.
When To Upgrade
If your use case is flat open terrain, long highway convoys, or a more permanent rig build, a higher-gain antenna can be worth it. For most users building the first MXT575 kit, the MXTA51 is the sane starting point because it removes the indoor-antenna penalty without asking for a permanent mount.
Our Verdict
The MXTA51 is the clean, hassle-free antenna upgrade for any MXT575 install — the factory magnetic-mount NMO kit means no drilling, no adapters, and guaranteed radio compatibility. For serious range in flat terrain, upgrade to the MXAT01VP fiberglass antenna ($195); the MXTA51 is the right call for most RV users who want plug-and-play performance.
