The satellite and TV signal finder is microprocessor controlled, making it very reliable and accurate. Signal strength is presented graphically on the LCD display in from of thermometer-scales and in numbers (0~99% ). It's of compact size and light weight, very convenient to use. Features: 2 in 1 satellite and TV signal finder is microprocessor controlled, making it very reliable and accurate. Compact and lightweight, easy to use. Digital LCD screen displays signal strength graphically, with backlight to enhance reading experience greatly; clear to read no matter in the day or at night. It's very sensitive and can detect the weakest of signals; strong incoming signals (power full satellite, big dishes, BVB-T Antenna, TV antenna ) can easily be attenuated for better readout. It can also present pitch tones on a buzzer; the higher tone, the better signal. Humanized design, with compass function for reference purposes. Note: Size and color may be slightly different due to manual measurement and different light conditions. Thanks for understanding.
