TV Aerial Installation in Porthmadog
Serving Porthmadog and the wider Gwynedd area, our network handles TV aerial installation with transmitter-aware advice — which here means Llanddona (Group A, horizontal) at 41 km. One installer per enquiry, free quotes.
Reception in Porthmadog
Porthmadog receives Freeview from the Llanddona transmitter , broadcasting on Group A with horizontal polarisation at 30 kW.
Aerials here point N (bearing ~1°) toward the mast, 41 km away. At 41 km out, a high-gain aerial is often the right call in Porthmadog, particularly for bungalows and sheltered streets.
Where terrain or buildings shadow Llanddona, installers working Porthmadog can often realign to Blaenplwyf (61 km south) or Moel y Parc (64 km north-east) — a decision made with a signal meter on the roof, not guesswork.
