When your off-road convoy ventures into Moab’s rocky canyons or Montana’s dense forests, losing communication isn’t just inconvenient—it’s life-threatening. Traditional CB radios often fail beyond 2 miles, leaving adventurers stranded in dead zones. Enter the Retevis RA87, a 40W GMRS mobile radio engineered to tackle rugged terrain with unmatched power and repeater compatibility. Whether you’re navigating remote trails or coordinating a multi-vehicle expedition, the RA87 ensures your team stays connected when it matters most.
In 2022, a Utah off-road group faced a nightmare scenario when two vehicles became trapped in a canyon after a rockslide. Rescue efforts were delayed by 6 hours due to failed CB radio signals, highlighting the dangers of relying on outdated technology.
Why Traditional Radios Fail Off-Road:
Low Power Output: Most CB radios operate at 4- 5W, struggling to penetrate dense forests or rocky landscapes.
No Repeater Support: Without a relay system, signals drop sharply in valleys or mountainous areas.
1. 40W High-Power Transmission
The RA87’s 40W mobile radio output
2. GMRS Repeater Mode for Extended Coverage
Turn the RA87 into GMRS repeater channel, then connect with your local GMRS repeater to amplify signals across vast distances:
Or you may mount our RT97S Portable GMRS repeater radio on high ground (e.g., a ridge or vehicle roof).
Program input/output frequencies (e.g., 462.550 MHz ➔ 467.550 MHz).
Connect to a high-gain antenna (like the Retevis MR300).
Result: Expand your range to 15+ miles—ideal for multi-group expeditions.
User Testimonial: Real-World Reliability
“During our Rubicon Trail expedition, two Jeeps broke down 8 miles apart. Thanks to the RA87’s repeater mode, we coordinated repairs without hiking for hours. This radio is a game-changer!”

No License Required: GMRS requires a $35 FCC license (covers family/business teams), unlike ham radio’s complex exams.
Crisper Audio: Digital noise reduction filters out engine roars and wind noise.
22 Channels + 121 Privacy Codes: Avoid interference from other groups.
Case Study: Surviving the Colorado Backcountry
A 4x4 team in Colorado’s San Juan Mountains used the RA87 to:
Alert Base Camp during a sudden snowstorm.
Guide Medics via repeater-enhanced signals when a member fractured a leg.
Without the RA87, rescue would have taken days.
Q: Can I use the RA87 without a GMRS license?
A: No, but the $35 license covers your entire team for 10 years.
Q: What antenna works best with the RA87?
A: Pair it with the Retevis MR300 as your Off-road antenna
Q: Is the RA87 compatible with FRS radios?
A: Yes! Sync with FRS handhelds (e.g., Retevis HA1G) for mixed-team comms.
