Why operators choose us
Built by radio people, for radio people
FAULT-FOUND, NOT GUESSED
Proper bench diagnosis
Your rig is checked with test equipment on the bench before we quote, so you pay to fix the real fault and nothing else.
LOW LOSS, LONG LIFE
Quality cable and connectors
Installations use Messi & Paoloni coaxial cable and connectors, fitted and weather-sealed so they stay low-loss for years.
DESIGNED IN-HOUSE
Our own ham radio tools
We design and build antenna switches, guying rings and other station hardware, and we can make custom parts for your setup.

Signal reports from our customers
QSL · REPAIR5 / 9
“My base station had no transmit for months. It came back working on every channel with the SWR meter reading right.”
QSL · ANTENNA5 / 9
“Neat install with proper low-loss coax and sealed connectors. Reports on 2 m improved straight away.”
QSL · PA5 / 9
“Clear explanation of the fault and the price before any work started. The amplifier has run perfectly since.”

About us
A workshop that speaks your language
RF Labs is run by people who operate radios as well as repair them. RF is radio frequency, everything we work on. Labs is the test bench, where every repair, calibration and new design is measured, not guessed.
- Repairs to CB, amateur and PA equipment
- Antenna systems planned around your site
- Tools and hardware designed in-house
Radio off air? Let’s get you back on frequency.
About RF Labs
A radio repair workshop and antenna installer founded by operators, for operators.
Our story
From the shack to the workbench
RF Labs (formerly HAM Radio Service Ireland) started the way many radio businesses do: friends and fellow operators bringing faulty rigs to someone who knew how to fix them. Word spread through clubs and on air, and the bench got busier.
Today we repair CB and ham radio equipment, fix and calibrate PA units, and install complete antenna systems. Along the way we started designing our own station hardware, because the tools we wanted were hard to find or not built well enough.
We are still radio operators first. That means we test the way you will use the equipment: on air, under load, with the meter connected.
Why RF Labs?
Radio frequency, measured on a proper bench
RF
Radio frequency
Everything we work on, from 27 MHz CB to HF, 2 m and 70 cm. Radios, PA units, antennas and the coax in between.
Labs
The test bench
Test equipment, not guesswork. It’s where we diagnose faults, calibrate equipment and design our own ham radio tools.
RF + LABS = MEASURED, NOT GUESSED.
Our mission
Keep every station in Ireland on air, sounding its best
Honest diagnosis, quality parts and installations that last, at a fair price explained before we start.
What makes us different
Four things you can count on
Specialists
Radio is all we do
We are not a general phone and TV shop. CB, amateur radio, PA units and antennas are our whole focus.
Materials
Messi & Paoloni cable
We fit Messi & Paoloni coaxial cables and connectors because low loss and a good seal matter over the life of an antenna system.
Transparency
Quote before work
We diagnose the fault, explain it in plain words and agree the price with you before a repair goes ahead.
Engineering
We build our own gear
Our antenna switches and guying rings come from our own design work, tested at our station before we sell them.

FAQ
Common questions
Which radios do you repair?
We repair CB radios, amateur (ham) transceivers and handhelds, and PA units and amplifiers. If you are unsure about your model, send us the make and model and we will tell you.
Do I get a quote before the repair?
Yes. We diagnose the fault first and agree the price with you before any repair work goes ahead.
Can I send my radio by courier?
Yes. Contact us first and we will tell you how to pack the equipment and where to send it.
Why do you use Messi & Paoloni cable?
Messi & Paoloni coaxial cables have low loss and consistent build quality, which keeps more of your power at the antenna and lasts longer outdoors.
What does calibration include?
Depending on the equipment, calibration covers frequency accuracy, deviation, output power and meter readings, checked against our reference test equipment.
Do you install antennas outside your local area?
Installations are arranged case by case. Tell us your location and what you need, and we will confirm availability.
