Midland MXTA51 MicroMobile 2.1dB NMO Replacement Antenna Kit
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

- ASIN unverifiable via Amazon (bot-walled) — sold primarily through Midland direct and specialty radio retailers
Our Verdicts
Garmin inReach Mini 2 Satellite Communicator
The inReach Mini 2 is the premium last-resort layer. It belongs in the kit when a balcony, roof, courtyard, or evacuation route gives you enough sky view to send messages after cell service fails.
Midland MXTA51 MicroMobile 2.1dB NMO Replacement Antenna Kit
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.
