Antennascope is your all-in-one tool for finding the best TV transmitters and perfectly aligning your antenna — no professional installer needed. Simply enter your postcode or use GPS, and Antennascope instantly finds the nearest transmitters, estimates signal strength, and shows you exactly which direction to point your aerial. The built-in compass guides you in real time until you're locked on target. FIND YOUR TRANSMITTER Search by postcode, ZIP code, or current GPS location. Antennascope calculates the distance, bearing, and estimated signal strength for every transmitter in range. Results are ranked so you can quickly identify your best option. REAL-TIME COMPASS ALIGNMENT Open the compass and rotate your antenna until you hit the green zone. The live heading display shows exactly how many degrees to turn and in which direction. An on-screen signal meter and "ON TARGET" indicator confirm when you're perfectly aligned. INTERACTIVE MAP See all nearby transmitters plotted on a map alongside your location. Tap any pin to view full transmitter details including channels, power output, and distance. Plan your installation before you even pick up the aerial.
