Guardian: Unbreakable NiTi Antenna for SAR & Public Safety (155/465 MHz)

Guardian is Iron Spear’s 155/465 MHz handheld BNC antenna for SAR and public-safety operators — the non–amateur-dual-band SKU in the NiTi HT line. Same Idaho in-house build and flexible NiTi/nitinol element approach as Maximus; different band focus. “Unbreakable” means NiTi spring-back / daily-carry resilience, not mil-spec. Claim-safe: we state frequencies and handheld BNC form factor; we do not invent range or power claims for SEO. For amateur dual-band 2m/70cm see Maximus; for 440 MHz see Minimus. Collection: ham radio antennas. Adapters: Handheld Radio Adapter Guide.

  • Frequencies: 155/465 MHz (SAR / public safety)
  • Material: Nitinol (Nickel Titanium)
  • Connector: BNC
  • Price: $56
  • Made in Idaho

Design Philosophy

Unbreakable. Clear. Reliable.

Stop letting flimsy antennas compromise your signal. The Guardian Series is handcrafted from flexible Nickel Titanium (NiTi) for crystal-clear dual-band performance, precision-tuned for Public Safety (155/465MHz) operations even in the harshest conditions. NiTi spring-back — bends and returns for daily carry. Built for hard work. Backed by a Lifetime Warranty.

Why Guardian is Your Best Choice:

  • NiTi Spring-Back: Premium Nickel Titanium — bends and returns for daily carry.
  • Public Safety Optimized: Tuned specifically for SAR, Fire, and EMS bands where life-safety communication is non-negotiable.
  • Handmade Quality: Meticulously built in-house at the Iron Spear shop for peak performance.
  • Optimized SWR: Efficient power transfer for a stronger, cleaner signal on critical mutual aid channels.
  • Lifetime Warranty: Built to last, guaranteed for life against manufacturing defects.

Engineered for the Reality

Every feature of the Guardian is designed with the realities of the field in mind:

  • Lightweight & Flexible: At approximately 18" long, its highly flexible design prevents snagging on branches as you move through thick brush and won't weigh you down.
  • Boosts Performance: As a 1/4 | 3/4 wave monopole antenna, it is specifically tuned to maximize your signal range and clarity on 155/465Mhz frequencies, giving you a distinct advantage over standard equipment.
  • Durable Construction: Built to withstand the harsh conditions of the backcountry, the Maximus can be bent, twisted, and abused and will still be ready when you need it.
  • Broad Radio Compatibility: The standard BNC connector ensures it works seamlessly with a wide range of popular handheld radios right out of the box, including models from Baofeng, Retevis, Anyton, Yesu, Quansheng, Wouxun, Btech, Tidradio, and more.

The Guardian is the ultimate all-around antenna for any one who demands an antenna that provides a significant, reliable performance boost in any scenario.

Don't settle for less.
