The short answer
Television and antenna service covers crank-up and powered antennas, signal boosters, coax and splitter faults, satellite domes, and TV mounting or replacement. Work runs $300 to $3,500, or 1 to 14 hours at $260 per hour plus parts. Estimates are $150, refundable against an authorized repair.
01
What this work actually involves
Most no-signal complaints are not the antenna. They are the coax path behind the wall. RV coax is run with cheap splitters, wall plates that were never torqued, and a booster module whose power injector has quietly died, and any one of those drops the signal enough to kill a digital broadcast picture entirely. Digital television has no gradual degradation. It works or it does not, which hides a marginal path until it crosses a threshold. We sweep the run from the antenna head to each wall plate and find the actual loss rather than replacing the head on a hunch.
The mechanical antennas fail on their own schedule. Crank-up bat wing units seize at the elevating gear after the grease dries out, which happens fast in Southern California heat, and owners force them until the crank shears. The plastic head goes chalky and brittle under UV, then cracks along the arm. Powered dome antennas fail at the motor, the elevation belt, or the controller, and the symptom is the same searching loop forever. We identify which of those it is before quoting a replacement head.
Roof mounting is the part with consequences. Any antenna, booster, or dome is a set of roof penetrations, and the ones we replace are frequently leaking through the base gasket long before the electronics fail. When we service or replace a roof antenna, the mount gets rebedded and resealed to the membrane and the penetration gets water tested. That is not an upsell, it is the difference between a TV repair and a ceiling repair two years later.
Systems and brands we work on: Winegard, King, Furrion.
Location: All work is performed at our Yorba Linda facility. We do not offer mobile, roadside, or fleet route service.

03
When you need this service
- No channels found on scan even with a strong local broadcast signal
- Picture works on one television in the coach but not another
- Crank-up antenna is stiff, will not raise, or the crank spins with no effect
- Antenna head is chalky, cracked, or missing a section of the arm
- Satellite dome searches continuously and never locks
- Water staining on the ceiling around the antenna base
- Television that shifts or comes loose from its mount while traveling

How we do it, step by step
- 01
Signal path sweep
We measure signal at the antenna head, at the booster, at each splitter, and at every wall plate. The loss shows up at a specific point rather than being guessed at.
- 02
Booster and power verification
Power injector output and booster function tested directly. A dead injector is the single most common cause of a coach that suddenly finds no channels at all.
- 03
Mechanical antenna inspection
Elevating gear, crank shaft, and head condition checked on bat wing units. Motor, belt, and controller checked on powered domes to identify the actual failed component.
- 04
Roof mount and seal inspection
Base gasket and surrounding sealant inspected while we are on the roof, because a leaking antenna base is common and it becomes a ceiling repair if it is ignored.
- 05
Repair or replacement
Failed coax re-terminated or replaced, splitters upgraded, heads or domes replaced, and mounts rebedded and resealed to the roof membrane.
- 06
Verification and water test
Channel scan confirmed at every television in the coach, dome lock verified where applicable, and any disturbed roof penetration water tested.

Questions about tv, antenna and satellite service
Frequently asked questions
Why does my RV antenna suddenly find no channels at all?
The most common cause is a failed booster power injector, the small wall plate module that feeds voltage up the coax to the amplifier in the antenna head. When it dies the signal drops below the digital threshold and every channel disappears at once rather than degrading. It is an inexpensive part and a fast test.
How much does antenna and TV service cost?
Work runs $300 to $3,500, or 1 to 14 hours at $260 per hour plus parts. A booster injector replacement and a signal sweep is at the low end. A powered satellite dome replacement with new roof sealing, coax runs, and two televisions replaced and remounted is at the high end.
My crank-up antenna will not go up. Is it worth repairing?
Often yes. The usual failure is dried grease in the elevating gear or a stripped crank shaft coupling, and both are serviceable. If the head itself is UV cracked or the arm has separated, replacement is the better value because a brittle head will keep shedding pieces. We tell you which one you have before quoting.
Can you mount a larger television in my coach?
Yes. The constraint is structure and travel loads, not screen size. A television that is fine sitting still can tear its mount out on a rough freeway. We locate framing, use a mount rated for the weight with a travel lock, and make sure the cabinet or wall behind it can actually carry the load.
Do satellite domes still make sense with streaming?
For many owners, yes, particularly those who camp where cellular coverage is poor. Winegard and King domes still work well for television, and they pair fine with a separate data connection. If you are already adding Starlink, we plan the roof layout for both at once so the mounts and penetrations are laid out sensibly.
