⚠ This Radio Has Been Discontinued
The Vertex Standard VX-451 is no longer manufactured or available for purchase, Vertex Standard has retired the entire VX-450 Series.

The VX-451 5 Watt 16 Channel UHF or VHF Radio from Vertex Standard was a rugged, no-display analog portable business radio from the VX-450 Series, engineered to keep working in tough environments. Built water-submersible and offered with HazLoc consideration, the VX-451 was a dependable choice for harsh conditions and hazardous locations. Because the Vertex Standard VX-451 has reached end-of-life, this page is maintained so existing owners can find specs and a current replacement, and today that role is filled by the Motorola CP100d.

Recommended Replacement: Motorola CP100d
With the Vertex Standard VX-451 discontinued, the Motorola CP100d is the recommended path forward, a current non-display analog business radio that delivers the same simple, rugged operation the VX-450 Series was known for, with dual-mode analog and digital operation for an easy upgrade path. Fleets that want more capacity can step up to the Motorola BPR50dX, while teams needing a digital license-free option can compare the Motorola CURVE DLR110. Need to keep your replacements running?

Who the VX-451 Was Built For
The VX-451 served crews working in harsh conditions and hazardous locations, industrial sites, utilities, and field operations that needed a water-submersible analog radio with strong interoperability and built-in worker-safety alerts. Owners replacing that workhorse can move straight to the Motorola CP100d, or explore lighter-duty options in our license-free two-way radios collection. Not sure which direction fits your fleet?
