Fix "No Signal," "Check Antenna," and "Antenna Error" issues fast. Certified technicians, same-day service, and a cost-effective alternative to dealership repairs — coast to coast.
Expert diagnosis and repair for all SiriusXM issues — from "No Signal" to full antenna replacement.
SiriusXM uses a completely different technology than regular AM/FM radio. Instead of a standard mast antenna, it relies on a special satellite patch antenna (also known as SDARS) that receives signals from both satellites and ground-based repeaters in cities.
When your SiriusXM stops working, the problem is almost always one of three things: a failed antenna unit, a damaged cable or connector, or a failed tuner module. Our technicians diagnose the exact fault within 30 minutes.
We offer a cost-effective alternative to dealership repairs. Where dealers often quote $500–$1,200 for a full module replacement, we can usually fix the root cause for $75–$350.
Specialized SDARS diagnostics & repair
If you're seeing any of these on your SiriusXM display, we can help.
Your radio cannot see the satellite. Usually caused by an obstruction, a failed antenna, or a damaged cable. We diagnose the exact cause within 30 minutes.
The radio detects a physical fault in the antenna circuit. Typically indicates a disconnected, damaged, or corroded cable, or a failed antenna unit.
Audio cuts in and out even in open sky. This often points to a partially failed antenna or a marginal cable connection that degrades over time.
Radio shows "Acquiring Signal" indefinitely. Could be a failed tuner module, a broken antenna, or a short in the coax cable.
Roof-mounted shark fin antenna cracked, broken, or damaged in a car wash or accident. We replace with OEM-equivalent units.
Moisture intrusion into the antenna base or cable causes intermittent signal loss. Common in coastal areas and after heavy rain.
No hidden fees. Diagnostic inspection is free with most service calls.
Simple troubleshooting you can do yourself before calling us.
Drive away from tall buildings, trees, parking garages, or tunnels. SiriusXM needs a clear view of the sky.
Turn off your car, open the driver's door, wait 3 minutes, then restart. This resets the SDARS tuner.
If accessible, inspect the antenna cable at the back of the radio. Look for loose or corroded connectors.
If the issue persists after steps 1–3, it's likely a hardware fault. Our team can diagnose it within 30 minutes.
We provide on-site and workshop-based SiriusXM repair, car antenna repair, and broadcast services across major US markets.

Real feedback from SiriusXM subscribers, car owners, and broadcast professionals.
"My SiriusXM kept showing 'Check Antenna' for weeks. The dealer quoted me $850 for a new module. These guys found a corroded connector, replaced it for $120, and it's been perfect since. Saved me $700!"
"My shark fin antenna was cracked after a car wash. They replaced it in under 90 minutes at my office parking lot. SiriusXM works perfectly now."
"Our station's FM transmitter went down on a Sunday. Their engineer was on-site within 2 hours and restored the signal before our evening broadcast."
Answers to the most common SiriusXM and car antenna questions.
A "No Signal" message usually means the satellite antenna cannot see the sky — often caused by tunnels, parking garages, tall buildings, or heavy tree cover. An "Antenna Error" or "Check Antenna" message typically indicates a physical problem: a disconnected, damaged, or corroded cable, or a failed antenna unit.
Our technicians can diagnose the exact cause within 30 minutes.
Yes. SiriusXM antenna repair is a core part of our service. This includes diagnosing signal loss, repairing damaged cables and connectors, and replacing failed satellite antenna units — such as the "shark fin" style on the roof.
We can often replace a failed antenna for a fraction of dealership prices. All repairs come with a 90-day warranty.
Could be a temporary obstruction (like a large building or storm) that resolves on its own. More persistent issues are often caused by a failed antenna unit or damaged cable.
Try a "Power Cycle": turn the car off, open the door, wait 3 minutes, restart. If the problem persists, our technicians can diagnose it.
If your vehicle is still under its original factory bumper-to-bumper warranty, a faulty factory-installed SiriusXM antenna may be covered. However, many dealerships treat the antenna as a wear item.
If it's not covered, our independent repair service is a cost-effective alternative — often saving $300 or more.
Typically $75 to $350 depending on the fault and vehicle type. Cable or connection repair usually runs $75–$150. Full shark fin antenna replacement runs $150–$350 including parts and labor.
Diagnostic inspection is included free with most service calls, and we always provide a transparent quote before starting work.
AM/FM radio uses a standard vertical mast antenna. SiriusXM — also known as SDARS (Satellite Digital Audio Radio Service) — uses a special satellite patch antenna receiving signals from space, plus ground-based repeaters in cities.
You cannot receive SiriusXM on a standard AM/FM antenna. This is why SiriusXM issues require specialized diagnostic equipment.
Most repairs complete within 45 to 90 minutes. Cable and connector repairs take under an hour. Full shark fin replacement usually takes 60 to 90 minutes.
We always provide a time estimate before starting work. Mobile on-site service is available in most US service cities.
