Dual-Band Maximus Mobile Antenna (NMO)
Maximus Mobile: the vehicle antenna that will not snap, bend, or stay bent.
Fiberglass whips snap on the trail. Steel whips bend on the first low branch and never sit straight again. The Maximus Mobile is the vehicle-specific, heavy-duty evolution of the handheld Maximus: handcrafted from ultra-thick 3mm Nickel Titanium (Nitinol), it takes direct strikes from tree branches and heavy brush at vehicle speed and springs straight back to true zero. Built for overlanding, off-road, and vehicle-mounted TAK comms, and pre-tuned for dual-band 2m/70cm on a vehicle roof ground plane.
Why Maximus Mobile:
- Virtually indestructible: 3mm Nickel Titanium, the thickest whip Iron Spear builds. Bend it, twist it, it returns to form.
- No base-loading coil: a slip-fit NMO design with wider usable bandwidth across VHF and UHF.
- Vehicle-tuned: 19.5" length optimized for a center-roof ground plane, with low SWR on both bands.
- Pairs with your handheld: run your BTECH UV-PRO or any 2m/70cm radio through an NMO mount for real mobile range.
- Handmade in the USA: built in-house by Iron Spear Outfitters and backed by their Lifetime Warranty.

High SWR can damage your radio. This antenna is pre-tuned for standard center-roof mounting, but every vehicle ground plane is different, so verify your antenna system's SWR before transmitting.
