About Radiofrequency
Typical signal readings to expect
Signal level is measured in dBm. For most digital services, readings between about -10 dBm and -45 dBm at the receiver are considered acceptable. Signal-to-noise ratio above 25 dB usually means clean reception. Bit error rate should be low. If the technician reports values far outside these ranges, further diagnosis is needed.
What affects the final price
Final cost depends on parts used, the height and access of the antenna, cable run length, and how many wall outlets are involved. Emergency calls, roof work, or special mountings raise the price. Older homes with outdated cabling may need extra labour. Always ask for a written breakdown before approving the work.
Mistakes homeowners often make
Many people buy high-gain antennas when the real problem is poor cabling or loose connectors. Others install amplifiers without checking input signal, which adds noise instead of fixing reception. Running new cable next to electrical wiring also causes interference. Replacing parts without measuring first usually wastes money and leaves the original fault untouched.
Maintenance after installation
Check outdoor connections every 6 months for corrosion or water ingress. Keep antenna mounts tight, especially after storms. Replace damaged cable sections promptly, since shielding breaks down over time. Re-measure signal levels once a year to confirm performance. Avoid stacking splitters, as each one reduces signal strength and can cause long-term reception problems.
Signs you need a technician
Pixelation, freezing frames, missing channels and weak signal on some televisions point to antenna or cabling faults. Other clues include corrosion on outdoor connectors, water inside wall plates and amplifiers that stay warm without improving picture quality. A professional can measure signal levels and isolate the faulty component.
Common parts replaced
Frequent replacements include coaxial cable RG6, F-type connectors, baluns, splitters, masthead amplifiers and power injectors. Weather seals and UV-resistant cable ties are also swapped when brittle. Older antennas with rusted elements are usually replaced entirely rather than repaired, since new units perform better and last longer.
Time required for the job
A simple splitter or cable repair takes 30 to 60 minutes. Replacing a rooftop antenna with new cabling usually needs 2 to 4 hours, including mast installation and grounding. Adding wall points in two rooms may extend the visit by another 60 to 90 minutes per point.
Questions to ask before hiring
Ask whether the quote includes parts and labour, what warranty covers the work and whether the technician measures signal after installation. Confirm if they will seal outdoor connections, ground the mast and clean the area afterwards. A written estimate protects both sides.
Safety during the work
Roof work involves ladders, antennas near power lines and drilling through tiles or walls. A trained technician uses a harness on steep roofs, disconnects nearby power if drilling near cabling, and verifies mast grounding with a tester. Never climb a wet roof or touch aerials during a storm.
When replacement beats repair
If the antenna is older than 10 years, the cabling is degraded, or signal quality remains low after alignment, full replacement is usually more cost-effective than repeated repairs. Modern antennas handle digital and high definition signals with less amplification, reducing long term maintenance and power consumption.
