How to spec a two-way radio fleet for a job site
Most radio fleets are over-spec'd in one area and under-spec'd in another. This guide walks the four decisions that actually change performance on a job site, so you order once instead of returning half the box.
Speccing a fleet is not about the flashiest handset. It is about matching band, power, and accessories to the physical site and the way your crew works. Get those right and a mid-tier radio outperforms a premium one deployed carelessly.
1. Pick the band before the model
Band is the first fork, and it is hard to reverse once you have bought handsets. UHF penetrates concrete, steel, and interior walls better, which suits construction, warehouses, and multi-floor buildings. VHF travels farther over open, flat ground, which suits large outdoor sites, agriculture, and campuses with clear line of sight.
Open outdoor / long range → VHF (136–174 MHz)
If your site is mixed, default to UHF. It is the more common commercial band and the accessory ecosystem is deeper.
2. Plan channels around teams, not people
Count working groups, not headcount. Security, logistics, and management each want their own channel so traffic stays clean. A 16-channel radio covers most job sites with room to grow. Reserve one channel as an all-call for emergencies.
- One channel per working group that talks independently
- One shared all-call channel for site-wide alerts
- Headroom of two to three unused channels for future crews
3. Match the IP rating to the environment
An IP rating tells you how the radio handles dust and water. On an exposed site, under-rating this is the fastest way to kill a fleet. Look for IP54 as a working minimum for outdoor use, and IP67 where handsets get rained on, dropped in mud, or rinsed down.

4. Know when a repeater pays for itself
If crews lose contact across the far end of a site or between floors, a repeater extends coverage without buying higher-power handsets. The math is simple: one repeater plus antenna often costs less than upgrading an entire fleet to chase range. For sites above roughly ten floors or a few hundred yards of obstruction, price the repeater first.
The one-page checklist
- Band chosen for the structure, not the brochure
- Channels mapped to working groups plus an all-call
- IP rating matched to real site conditions
- Batteries and chargers ordered for the full shift pattern
- Repeater priced before over-buying handset power
