Fixing bad TV reception: how to hire an antenna technician
Why the antenna often isn't the culprit, how technicians price a job, and the signal test that tells you whether a quote is honest.
A pixelating picture, a channel that drops out whenever the wind picks up, a new TV point that never quite works — antenna problems are maddening precisely because the cause is hidden on the roof or inside the walls.
The good news is that a competent technician can usually diagnose it in one visit, and the fix is often cheaper than you'd fear. Here's what the work involves and how to make sure you're paying for the right thing.
What antenna technicians actually do
Most call-outs are diagnosis before they're repair. The technician tests the signal at the wall point, then works back — cabling, connections, splitters, the amplifier if there is one, and finally the antenna itself. A surprising share of reception problems turn out to be corroded connectors, water in an old cable, or a splitter quietly halving the signal to every room, none of which need a new antenna.
When the antenna genuinely is the problem, they'll replace it with a digital antenna suited to your signal area, realign it, and often add a masthead amplifier if you're far from the transmitter. Running extra TV points to other rooms is the other common job — each point means a cable run and a bit more labour.
This sits alongside the electrical trades but isn't the same thing: antenna cabling is low-voltage coax, not mains wiring. If a job strays into powering an amplifier from a new circuit or touching the switchboard, that part belongs to a licensed electrician.
How the cost works
Antenna work is usually quoted as a fixed price covering the call-out, parts and labour. A straightforward repair or realignment sits at the lower end — a couple of hundred dollars is typical. Supplying and installing a new digital antenna on a single-storey roof lands in the middle, and a full job with a new antenna, amplifier and a couple of extra wall points runs to the top of the range. These are indicative bands only; the live estimate on this page adjusts for your roof and how many points you need.
Two things push the price up: roof height and extra points. A two-storey or steep roof takes longer and may need extra safety gear, and every additional wall point adds a cable run. If only one TV misbehaves while the rest are fine, the fault is almost certainly that room's cable or point — not the antenna, and not a whole-house job.
Choosing the right technician
Antenna work isn't a licensed trade in its own right, so evidence does the job a register would. The single best signal of a good technician is that they test signal strength at every point before and after the work — and are happy to show you the readings. Someone who wants to replace the antenna before measuring anything is guessing, or selling.
Ask for the quote to spell out whether parts like amplifiers and splitters are included, and whether the price holds if the roof turns out to need more than expected. A technician who talks through the likely causes before climbing up, rather than promising a new antenna sight unseen, is the one to book.
Mistakes to avoid
Most antenna regrets are about paying for a replacement when a repair would have done, or a whole-house fix for a single-room fault.
- Agreeing to a new antenna before anyone has tested the actual signal at the wall
- Assuming a whole-house problem when only one TV is affected — that's usually a single cable or point
- Not asking whether amplifiers, splitters and cabling are included in the quoted price
- Ignoring old, water-damaged coax — new antenna, same rubbish cable, same picture
- Letting an antenna installer do mains electrical work that legally needs a licensed electrician
- Booking one extra point now and another next month — batch the cabling into one visit
