Radio Repeaters Explained: How to Cover a Whole Site

When handheld radios stop reaching from one end of your site to the other, the answer is usually not more powerful handsets — it is a repeater. This guide explains what a repeater does, who actually needs one, and how to choose between the two Hytera models we install most.

What a repeater does

A repeater is a fixed radio installed at a high point on your site — a plant room, tower or roof space — that receives every transmission and instantly re-broadcasts it at much higher power through a properly sited antenna. Handhelds talk 4-5 watts at chest height; a repeater talks up to 50 watts from the best position on the building. The practical effect is that two radios that cannot hear each other directly both hear the repeater, so the whole site lands on one reliable channel.

Who actually needs one

You are a repeater customer if any of these sound familiar: a multi-building campus such as a college or university, a holiday park spread over open acres, a golf course with dead ground between the clubhouse and the far holes, or any site where basements, lift shafts and thick walls swallow the signal. If handhelds cover the site fine today, you do not need one — and we will say so.

The two repeaters we install most

The Hytera HR655 (from £1,700 ex VAT) is the value pick for single-site coverage up to 25W — schools, mid-size estates, warehouses. The Hytera HR1065 (from £2,260 ex VAT) steps up to 50W with a 100% continuous duty cycle, battery backup support and IP multi-site networking — the campus and large-estate anchor. Both run DMR digital and analogue at the same time, so a mixed fleet keeps talking while you migrate.

Licensing and installation

Every repeater needs an Ofcom licence — usually Simple Site Light at £75 for five years for a single site, or a Technically Assigned licence for exclusive frequencies. We handle the application with your order, pre-program the repeater and your handsets to match, and can arrange antenna installation. Tell us the site layout and we will spec the whole system as one quote.

Will a repeater work with my existing radios?

Almost certainly. Any DMR or analogue radio on the right band can work through a repeater once programmed with the repeater channels — including mixed fleets during a digital migration.

How much extra range will I get?

As a rule of thumb a well-sited repeater roughly doubles handheld-to-handheld range and, more importantly, removes dead spots. The honest answer depends on antenna height and terrain, which is why we spec each site individually.
