RF problems should be measured, not guessed.

Short range, unstable reception or problems limited to specific zones may be caused by the radio, coaxial cable, connectors, antenna, installation position or real coverage conditions. We therefore check the complete RF path.

RF measurements and antenna systems
Control points

The problem is separated into measurable elements.

A symptom is not a diagnosis. The radio, programming, RF path, antenna system and the way the system is used are checked separately.

25–4.000 MHzMeasurements and checks in the frequency range documented for Radio Integral RF services.

SWR / VSWRChecking antenna and RF-line matching shows how much energy is reflected back toward the transmitter.

Output powerMeasuring transmit power helps distinguish a radio fault from losses in the antenna system.

Cables and connectorsLosses, oxidation, a poor connection or mechanical damage can degrade the entire RF chain.

Documented equipment from Radio Integral RF practice.

Radio Integral RF documentation includes the BIRD SA-4000 Site Analyzer, Motorola S-1350C wattmeter and BIRD Model 43 wattmeter, shown here using authentic archive material.

Six points checked as one system.

The check follows the radio signal from the transmitter, through the cable and antenna, to the actual location where reliable communication is required.

Transmitter

RF output power and radio behaviour.

Reflected power

Reflected energy indicates mismatch or a problem in the RF path.

Cable and connectors

Losses, oxidation and mechanical damage can limit the entire system.

Antenna

SWR/VSWR, resonance, position and installation method.

Location

Buildings, terrain and obstacles change the real RF result.

Critical zones

Communication is finally verified where the user actually needs it.

Tuning a mobile antenna is more than simply mounting it.

For taxi and other mobile users, antenna position, mounting method, vehicle ground plane, connector, coaxial cable and operating frequency are checked as one installation. Radio Integral has long-standing practical experience with mobile taxi antenna adjustment.

Send the equipment model, frequency, location and symptom.

This allows us to determine whether the next step should be device service, RF measurement, installation verification or broader coverage analysis.
