SignalScout 40

Signal Level Meter for Over-The-Air and Cable TV

Now Available!


New low cost over-the-air, digital TV antennas provide viewers free access to digital Over-The-Air (OTA) Broadcast TV (ATSC 1.0). Free use of major network broadcasts has made “Cord Cutting” a growing trend that allows users to reduce or eliminate high cost paid services.

The SignalScout (SS40) allows for optimum antenna alignment as it is installed. The meter provides fast and accurate measurement of signal strength when tuning an antenna for a local TV channel. The SignalScout has a built-in compass to give a starting point for aiming the antenna.

Antenna costs are moderate but installation costs can be high without the proper test tools. Traditional rooftop installations require numerous trips up and down a ladder to point the antenna and then go to the TV to determine if there is adequate signal for each channel.

The SignalScout  produces an audible tone that is proportional to the received signal strength so the user  does not even have to look at the display to get the best antenna alignment.

The SignalScout includes a 10dB amplifier for receiving weak signals from distant stations. This lets the user know if an amplifier must be installed in the home system for certain TV stations.

The SignalScout can be used to measure a single channel or an entire channel plan. There is also a learn mode to develop a channel plan for a specific location. The meter measures Signal level, Signal to Noise Ratio (SNR)/Modulation Error Ratio (MER), Tilt and provides Digital Error counts to verify the quality of the received signals and maintain or troubleshoot after installation.

The SignalScout also verifies CATV service. The unit is 64/256 QAM fully compliant and DOCSIS 3.1 (OFDM) signal level compatible. Noise return power is measured through a 42MHz low pass filter.


The SignalScout is an affordable high quality Signal Level meter for contractors and technicians installing digital antennas for OTA TV.
