• Requires 1 x 9V battery
• Frequency range: 40-862MHz
• Input Level: 50-90dBuV
NOTE: This unit only measures over the range 50-90dBuV, which is the recommended signal strength for interference-free Digital TV reception. Most modern Digital TV tuners can actually operate down to about 25dBuV and still produce a good picture, but only in the complete absence of any electrical interference. Therefore you may encounter the situation where the indicator LEDs appear to be showing there is no signal, even when the TV is displaying a good picture. What it’s really telling you is that the signal level is below the minimum recommended 50dBuV.
