Why is my TV signal bad in Bunbury?

It is almost always signal quality, not the TV.

When a Bunbury TV pixelates, freezes or loses channels, the instinct is to blame the television. In reality, the set is rarely the problem. Modern TVs have good tuners, but a tuner can only work with the signal that reaches it. If that signal is being lost somewhere between the antenna on the roof and the wall plate behind the TV, every television in the house struggles. So the question is not what is wrong with the TV, it is where along the chain the signal is being lost, and in Bunbury the answer usually traces back to the coast.

The five causes we see most in Bunbury.

• Salt-air corrosion. Bunbury sits between the Indian Ocean, Koombana Bay and the Leschenault Estuary. That salt air corrodes antenna heads, elements and F-connectors, and corrosion is the single biggest cause of dropouts here, especially in Dalyellup, Australind and the bay-facing CBD streets.
• A failed masthead amplifier. The small powered box on the mast that boosts weak signal dies after a few salt-air years. When it goes, the channels it was lifting drop out.
• Water in the coax. Cheap builder-grade RG59 with a cracked sheath wicks moisture down the cable run, degrading the signal a little more each wet season.
• Antenna off aim. Bunbury’s coastal fronts shift antennas off the Mount Lennard bearing. A few degrees of drift is enough to drop the weaker multiplexes.
• Fringe reception and tree cover. Treed Gelorup blocks and lower-lying Withers pockets sit in a weaker signal area, made worse when wet leaf cover absorbs the signal.

How we find the real cause.

We do not guess and swap parts. We meter signal strength and quality at the antenna, at any amplifier, and at the wall plate, so we can see exactly where the signal is being lost. That is the difference between a real fix and a band-aid that has you calling again in a month. As a worked example: a recent Withers home had ABC and SBS pixelating for months. Metering showed strong signal at the antenna but a sharp drop after a corroded masthead amplifier. We replaced the amplifier and resealed the down-lead for $210, fixed in one visit, with no new antenna needed.

What the fix costs.

Most Bunbury signal faults are resolved with a repair and retune at $130 to $280, all-in. If the antenna head is corroded beyond saving, a fresh antenna installation from $280 is the better value, and we will tell you which way to go honestly.
