A communal aerial is never fixed at the socket
When several residents in a Cunit block lose channels, the problem is almost never their television. It is in the shared installation: the aerial on the roof, the head-end that amplifies and filters, or the cable and tap-offs running down through the building. So we always start at the top, measuring every channel at the head-end output, and work down floor by floor until we find where the signal is lost.
Everything the service covers is set out under communal TV aerials.
Blocks on the seafront and in the old town
Along the beach and in the centre of Cunit there are plenty of apartment blocks put up before the ICT regulations existed. Their installations have been patched for years: a new amplifier here, a replaced tap-off there, an extra socket added without working out the loss. The most common faults:
- Top floors fine and lower ones poor, or the other way round, from unbalanced distribution.
- Channels that freeze because the head-end does not filter mobile signals in the 700 MHz band.
- Drop-outs when summer arrives, as every television in a block that has been half empty all winter comes on at once.
- Roof hardware damaged by salt air: connectors, mast and junction boxes.
The usual answer is a programmable head-end unit with a 5G filter, set channel by channel, plus replacing the sections and tap-offs that are losing level. There is no need to rebuild the whole block if the measurements do not call for it.
A communal dish: one dish for the whole building
Cunit has many owners who want channels from their own country or satellite platforms. When each one puts a dish on the balcony, the facade fills up with aerials, the brackets corrode and sooner or later one comes down in a storm. The alternative is a communal satellite dish:
- One or two dishes on the roof, properly fixed, pointed at Astra 19.2° E or Hispasat 30° W according to what the residents ask for.
- A multiswitch that distributes the satellite signal and the terrestrial one through the same system.
- Sockets prepared in the flats that sign up, with capacity left for anyone who joins later.
We check first whether the building’s ducts will take the cable needed. If individual aerial work is what interests you, there is more under TV aerials and satellite dishes.
Terraced housing and estates with a shared aerial
In La Costa de Cunit and Els Jardins there are groups of terraced houses sharing one aerial. Here the challenge is distance: the cable runs many metres between houses, sometimes buried or along the facades, and the last houses receive less signal. We go over the amplification and the tap-offs so every home gets a correct level.
How we work with the owners
A visit with a field meter, a report on what we find, and a free written quote. We give notice of any loss of signal and, when we finish, check at the head-end and at representative sockets on each floor.
We come from Salou and group our Baix Penedès visits together; we also look after buildings in Calafell. There is more about the town on our Cunit page.
