Pre-order, there is a 3 week lead on these as we are only doing short sprint runs right now while we ramp up production.
Stop letting flimsy fiberglass antennas snap on the trail and compromise your comms, or metal antennas that bend and are never straight again. The Maximus NMO is a vehicle-specific, heavy-duty evolution of our flagship handheld antenna. Handcrafted from ultra-thick 3mm Nickel Titanium (Nitinol), it is virtually indestructible. Built for overlanding, tactical use, and serious off-roading, it will take direct strikes from tree branches and heavy brush at vehicle speeds and instantly spring back to true zero.
Pre-tuned for optimal dual-band (2m/70cm) performance on a vehicle ground plane. Backed by the Iron Spear Lifetime Warranty.
Mag mount sold separately
"WARNING: High SWR can damage your radio. While pre-tuned for standard vehicle center-roof mounting, always verify your antenna system's SWR before transmitting, as individual vehicle ground planes vary."

A Note From Our Workshop:
Each Maximus NMO is handcrafted in our shop. We're always improving, so your antenna might have slight variations or component updates from photos as we use the best available parts. The core Maximus quality and indestructible nature is always guaranteed.
*Performance Disclaimer: All SWR and gain (dBi) specifications are established through real-world testing using our calibrated equipment and Iron Spear magnetic mounts placed dead-center on a metal vehicle roof. Actual numbers can and will vary depending on your specific vehicle, grounding conditions, mounting location, and if a different style of mount is used. If you are not mounting this antenna in the center of a metal roof, you must ensure proper grounding and an adequate ground plane are established for optimal performance and equipment safety.
Design Philosophy
Engineered for the Extremes
Every feature of the Maximus NMO is designed with the realities of the field in mind:
- Precision Tuned: Cut/Ground/machined to an exact length, this antenna factors in the capacitive coupling of the heavy armor and the specific physics of a vehicle roof ground plane to deliver an optimized 1/4 wave (VHF) and 3/4 wave (UHF) harmonic resonance.
- No-Snag Armor: Fully encased in our heavy-duty armor to protect the element, prevent weather corrosion, and blend into your rig.
- Lifetime Warranty: Built to outlast your truck, guaranteed for life against manufacturing defects.
Additional Information
Why the Maximus Mobile is Your Best Choice:
- Overland Ready: Double the thickness of our standard Maximus. The 3mm NiTi wire refuses to snap, or maintain a bend, under harsh trail abuse.
- Custom NMO Base: No weak base-loading coils to break. Our custom-machined NMO base provides a rock-solid mechanical connection.
- Enhanced Bandwidth: The thicker 3mm element lowers the "Q" factor, providing a massive, forgiving SWR bandwidth across both VHF and UHF frequencies.
- Handmade Quality: Meticulously built in-house for peak performance, not mass-produced in a massive factory.
