Midland MXT115 vs MXT500 (2026): 15W or 50W GMRS MicroMobile?
The MXT115 and MXT500 share the same compact MicroMobile form factor and the same straightforward vehicle install. One puts out 15 watts. The other puts out 50 — the legal maximum for GMRS. Here's what that gap means in practice, who the MXT115 still makes sense for, and when to spend the extra money on the MXT500.
Quick Verdict
Buy the MXT500. The 15W to 50W power gap is real and meaningful, and Midland lists an antenna and magnet mount in the MXT500's box. The MXT115 makes sense only for a secondary vehicle install, campground-loop communication where range is irrelevant, or a strict budget constraint.

The 15W vs 50W Power Gap in Plain Terms
Moving from 15W to 50W is a 5.2 dB increase in transmit power. In ideal line-of-sight conditions, that's roughly 40% more communication range. In real-world terrain — hills, trees, buildings — the gap is more context-dependent, but power consistently matters most at the edges: the moment when a call either connects or doesn't.
In practice: two vehicles in a campground loop 300 meters apart will sound nearly identical on either radio. Two vehicles separated by a ridge, or trying to maintain contact across 10 miles of open ranch land, will notice the difference. The MXT500's 50W output gives you a meaningful margin at range — more calls completed, fewer dropped transmissions, better repeater access from fringe locations.
| Scenario | MXT115 (15W) | MXT500 (50W) |
|---|---|---|
| Campground loop (under 1 mile) | Adequate | Excellent |
| Trail convoy (3–5 miles, mixed terrain) | Marginal | Good |
| Ranch / rural coverage (5–15 miles) | Unreliable | Workable |
| Repeater access at range | Inconsistent | Reliable |
| Vehicle-to-vehicle in canyon or valley | Poor | Better, not guaranteed |
GMRS Maximum Legal Power
50W is the FCC-authorized maximum for GMRS mobile stations, and the MXT500 runs at that ceiling. When you buy the MXT500, you're buying the most power the GMRS rules allow.
What's Identical Between Them
Despite the power gap, both are Midland MicroMobiles: compact vehicle radios with a hand microphone, powered from 12V. Install steps are broadly the same for both.
Both have GMRS repeater channels and NOAA weather alerts. The MXT500's spec list adds an IP66 rating, up to 128 channels, noise cancelling and a PA function. Otherwise the main difference is how far your signal reaches.
| Feature | MXT115 | MXT500 |
|---|---|---|
| Form factor | MicroMobile | MicroMobile |
| Install complexity | Simple | Simple |
| GMRS channels (1–22) | Yes | Yes |
| Repeater channels (15–22) | Yes | Yes |
| NOAA weather | Yes | Yes |
| Output power | 15W | 50W (max legal) |
| Antenna included | Varies by listing | Yes (antenna + magnet mount) |
| IP rating | Not listed | IP66 |
| GPS / Bluetooth | No | No |
| Availability (Oct 2026) | Out of stock on Amazon | In stock, $439.99 |
Antenna: The Hidden Cost That Narrows the Price Gap
Midland lists an antenna and a magnet mount with cable in the MXT500's box. What comes with a 15W radio depends on the listing: some MXT115 listings were bundles with an antenna, others were the radio alone. If yours has no antenna, budget for one, and compare the all-in price rather than the radio alone.
Antenna Quality Matters as Much as Power
A 50W radio with a poor antenna will underperform a 15W radio with a quality antenna. Antenna height, gain, and coax quality all affect range more than many buyers expect. If you're upgrading from a handheld for more range, invest in a quality antenna regardless of which MicroMobile you choose.
Use Case Guide: Who Should Buy Which
- Primary vehicle for off-road or overlanding groups
- Ranch or rural property communication
- Long-distance convoy coordination
- Accessing repeaters at range
- Anyone who wants maximum performance
- Secondary or backup vehicle install
- Campground communication (range doesn't matter)
- Strict budget (if you can find one in stock)
- ATV, UTV, or small vehicle with limited power budget
- First GMRS radio before committing to a full setup
Consider the MXT575 if You Want the Cleanest Install
Same 50W, Same Price, Different Layout
The Midland MXT575 is also 50W, and as of October 2026 Midland sells it for the same $439.99 as the MXT500. Its selling point is the fully integrated control mic: every control is in the mic and the radio body hides out of sight. It does not add GPS or Bluetooth; Midland's spec list includes neither. The MXT500's list is longer (IP66, up to 128 channels, noise cancelling, PA), so pick the MXT575 for layout, not features.

Frequently Asked Questions
- How much more range does the MXT500 have over the MXT115?
- The 15W to 50W jump is about 5.2 dB — which translates to roughly 40% more range in ideal line-of-sight conditions, and a more meaningful difference at the edge of coverage where the extra power determines whether you complete a call or drop it. Real-world range depends heavily on terrain, antenna quality, and whether you're hitting repeaters. The MXT500's advantage is most noticeable at range and in broken terrain.
- Is the MXT115 worth buying if the MXT500 is available?
- Only in specific situations: secondary vehicle installs where you want a low-cost radio, campground-loop communication where range is irrelevant, or a genuinely tight budget. Note that as of October 2026 the plain MXT115 is out of stock on Amazon; the 15W MXT275 is the in-stock alternative. For any primary vehicle or serious off-road use, the MXT500 is the right choice. The performance gap is real and the install complexity is identical.
- Does the MXT115 come with an antenna?
- It depends on the listing: the MXT115 has been sold both alone and in bundles that include an antenna, so check what is in the box before you buy. Midland's MXT500 page lists an antenna and a magnet mount with cable in the box.
- Do both radios require a GMRS license?
- Yes. Both the MXT115 and MXT500 are GMRS radios that legally require an FCC GMRS license to operate. The license costs $35 and covers your entire household for 10 years. It requires no exam — just an application on the FCC's website. Operating without a license is a violation of FCC rules.
- Can both radios hit repeaters?
- Yes. Both the MXT115 and MXT500 support GMRS repeater channels 15-22, which offset to the standard repeater input frequencies. Either radio can access GMRS repeaters. With the MXT500's 50W output and a quality antenna, you'll hit distant and marginal repeaters reliably. The MXT115 may struggle with repeaters at range that the MXT500 accesses easily.
