PortugalTVMap helps you find nearby TDT (Televisão Digital Terrestre) transmitters, calculate the exact bearing to point your antenna, and check whether you have a clear line of sight — all from your iPhone or iPad. FIND TRANSMITTERS Browse over 260 TDT transmitters across mainland Portugal, the Azores and Madeira, with data sourced from ANACOM. Filter by distance (30–120 miles), minimum power, and region. Sort by distance, signal strength, power, bearing, or channel number. PORTUGAL'S TDT NETWORK All transmitters carry the same 7 national channels: RTP1, RTP2, SIC, TVI, RTP3, RTP Memória and ARTV. The key to great reception isn't which channel — it's which transmitter to point at. PortugalTVMap finds the best one for your location. AIM YOUR ANTENNA • Compass Bearing — live compass needle pointing to any transmitter with true and magnetic bearings • Point to Transmitter — interactive map with a draggable pin and bearing line • AR Pointer — augmented reality 3D arrow in the real-world direction of the transmitter, with on-target haptic feedback and "Bullseye!" confirmation • Radar Compass — all transmitters as dots on a radar display, colour-coded by power, with on-target vibration CHECK LINE OF SIGHT The Signal Path Profile shows an elevation cross-section between you and the transmitter using terrain data. Portugal's hilly terrain means line of sight is critical — see instantly if hills block your signal. The Aerial Height Calculator tells you exactly how high to mount your antenna to clear obstructions. COVERAGE ANALYSIS "What Can I Receive?" finds the best transmitter to point your antenna at, recommends the aerial type, polarisation, pointing direction, and minimum mount height. Since all transmitters carry the same channels, just point at the nearest one with clear line of sight. TV GUIDE Lists all 7 national TDT channels with direct links to the official broadcaster websites in Safari — check what's on RTP1, RTP2, SIC, TVI and more. ALL STATIONS MAP Every transmitter on a map with colour-coded pins by region (Norte, Centro, Lisboa, Alentejo, Algarve, Açores, Madeira). Drag your location pin to explore. Tap any pin for quick stats and links to full detail or satellite site view. FAVOURITES Mark transmitters as received with a green checkmark to track which ones you've tested. Rate transmitters 1–3 stars and access them quickly from your Favourites list. BILINGUAL Full English and Portuguese interface — switch in Settings at any time.
