11月9日的TV Antenna Pointer & Towers应用程序分析

Aim your TV antenna toward nearby over-the-air broadcast transmitters with an offline tower pointer, map, and compass. TV Antenna Pointer helps you compare possible aim points before you mount, move, or adjust an indoor, attic, RV, or outdoor antenna. FIND US BROADCAST TOWERS Use your current location to view listed US TV transmitters within 150 km (about 93 miles). Nearby sites are organized by distance so you can quickly compare a close transmitter with a larger cluster in another direction. Where reliable source data is available, a station entry can include its channel, network or call sign, distance, bearing, and signal-related details. If channel or power information is not known, the app labels it as unknown rather than filling in an estimate. FOLLOW A COMPASS BEARING Choose a transmitter or tower group and open the pointer. The compass places its direction in relation to the way your phone is facing, while a numeric heading gives you a reference for installation. A grouped site lets you aim toward multiple broadcasts sharing the same general location instead of treating each channel as a separate physical target. CHECK THE MAP The map shows your position, listed transmitter sites, and bearing lines together. It is useful for comparing several directions and for choosing a visible landmark along the same line. This can also help when nearby metal, appliances, a vehicle, or the antenna itself interferes with the phone compass. RESCAN AFTER ADJUSTING A built-in TV rescan guide explains the usual steps after moving the antenna: connect it, open the television's channel setup, run an antenna or air scan, and review the result. Menu names differ by TV manufacturer, so the guide focuses on the common process rather than one brand. OFFLINE LOOKUP, NO ACCOUNT The transmitter data used by the pointer is stored in the app, so the core lookup and aiming workflow can be used without a network connection. No sign-up or account is required. Location is used to calculate nearby sites, distance, and bearing. COVERAGE AND LIMITS Detailed channel and signal data is provided for listed US transmitters within 150 km. France and Portugal have separate direction-and-distance support for mapped sites within 80 km; channel and power fields may be unavailable there. Portugal locations are based on mapped OpenStreetMap sites. Canada, Australia and Thailand are covered as listed next. Beyond these countries the app does not claim transmitter coverage and does not substitute far-away fallback targets. For these three countries the app shows direction and distance for sites within 80 km and the published channel: • Canada: ISED records of operational digital TV stations, with channel • Australia: ACMA licensed transmitter locations, with channel • Thailand: NBTC registered digital TV sites, with MUX channels (operation not confirmed) TV Antenna Pointer does not measure live signal strength and cannot predict reception with certainty. Terrain, trees, buildings, antenna height and type, cabling, interference, weather, and transmitter operation can all affect the channels your TV receives. Use the direction as a starting point, then confirm the final position with your television's signal meter or repeated channel scans. Compass readings also depend on your phone's sensors and calibration.
