If you’re not sure what’s causing the problem, start with the issue that best matches what you’re seeing on screen.

These guides cover the most common Freeview and TV aerial problems we see across Sussex, from missing channels and pixelation to wrong transmitter tuning, intermittent signal, room-by-room faults and possible 4G or 5G interference.

Why These Problems Keep Happening

Most TV signal issues aren’t caused by the TV itself. They’re usually down to aerial movement, ageing equipment, damaged cabling, interference, or changes in signal conditions over time.

Understanding the underlying cause helps prevent repeat problems and unnecessary replacements.

When It’s Best to Call a Professional

It’s usually time to get help if the problem:

Has lasted more than a day
Keeps returning
Affects more than one TV
Only happens in certain rooms
Started after strong wind or bad weather
May be caused by damaged equipment, cabling issues or mobile signal interference

At that point, it’s often quicker and cheaper to have the system checked properly rather than guessing.

Frequently Asked Questions

How quickly can you attend my property?

In most cases we can offer a same-day or next-day visit, with a two-hour arrival window so you’re not waiting in all day. Emergency TV aerial and satellite faults are treated as a priority, and we’ll always be honest about the earliest slot we can realistically make.

Do you charge a call-out fee or for a quote?

We don’t charge just to talk to you. We’ll usually visit, test the signal and give you a free, no-obligation estimate before any work is done. If you’re happy with the price, we can normally complete the installation or repair during the same visit. You’ll always know the cost upfront.

What areas do you cover?

We’re based in the South East and regularly work across East Sussex, West Sussex and surrounding areas, covering both towns and rural locations. If you’re unsure whether we cover your address, just give us your postcode and we’ll confirm.

What TV and satellite services do you provide?

We install and repair TV aerials, satellite dishes, Freeview and Freesat systems, as well as multi-room TV points, TV wall mounting, Starlink and satellite broadband, communal systems, CCTV, Wi-Fi alarms, network cabling and home/office networking. If it involves reception, cabling or connectivity, we can usually help.

Do I need a new aerial for digital TV, Freeview or Freely?

Most modern aerials will cope with digital services like Freeview and Freely without issue, but older or damaged aerials can struggle after the digital switchover. We can test your existing aerial using professional meters and advise whether a repair or upgrade will give you the best long-term reliability.

My TV picture is breaking up or I’m getting “No Signal” – can you fix that?

Yes. Break-up or pixelation can be caused by a misaligned aerial, a damaged dish, water-damaged cables, worn connectors or issues with boosters and splitters. We test the signal at your aerial and at each TV point to identify the fault, and most reception problems can be fixed during the first visit.

What types of aerials do you install, and which is best?

We install roof-mounted aerials, loft aerials and specialist high-gain or log-periodic aerials. Roof aerials usually give the cleanest signal. Loft aerials are suitable where access or appearance is an issue, but they can be more sensitive to interference. We’ll recommend what gives you the most reliable reception in your specific location.

What’s the difference between Freeview, Freesat, Sky and streaming services?

Freeview (and the newer Freely-style services) use a standard TV aerial.
Freesat and Sky use a satellite dish.
Subscription services offer more channels and on-demand content.
Streaming services (Netflix, iPlayer, Prime Video, etc.) are delivered through your broadband, not your aerial or dish.
We can help you set up whichever combination gives you the best choice and the most stable signal.

Can you add extra TV points or set up multi-room TV?

Yes. We can add extra aerial or satellite points in bedrooms, kitchens, loft conversions and offices, and we can design proper distribution systems so that every TV gets a strong, balanced signal without interference. For satellite and Starlink systems we can also route new cabling neatly and safely.

Do you install Starlink and satellite broadband systems?

Yes. We install and mount Starlink systems, providing safe cable routing into the property, secure brackets or poles, and integration with your existing Wi-Fi and network hardware. Starlink is especially useful in rural areas where broadband speeds are low or unreliable.

Do you fit CCTV, alarms and network cabling as well as TV?

Yes. We install CCTV, Wi-Fi alarms, Ethernet cabling, access points, network switches and 4G/5G router setups. This allows us to give you a complete, reliable setup for TV, internet and security systems using one team.

Are your engineers qualified, insured and DBS-checked?

All engineers are fully trained, insured and DBS-checked. Our team works to industry standards, uses modern equipment and follows best practice for safety and reliability. You’re always dealing with professional, experienced installers.

Do you work on commercial and communal TV systems?

Yes. We design and maintain communal aerial and satellite systems, as well as IRS systems and commercial TV networks for flats, hotels, pubs, offices, gyms and other multi-screen environments. We regularly work with landlords, property managers and building contractors.

What guarantees do you offer on your work?

All new installation work comes with at least a 12-month guarantee on parts and labour. Many components carry longer manufacturer warranties. If anything related to our work goes wrong during the guarantee period, we’ll return and put it right.

What happens on the day of my appointment?

Your engineer will arrive within the agreed window, discuss the issue with you and check access. They’ll test the signal, inspect your existing equipment, explain the options and confirm the price before starting. Once the job is done, they’ll retest everything, show you it working, and tidy up. Old or unsafe equipment can be removed if needed.
