Review on DVB-T Digital Signal Finder Meter: Aerial Terrestrial TV Antenna Satellite Signal Strength Meter with Compass for Improved TV Reception Systems by Michael Walker

I don't say that often, but it was a piece of crap. The instructions say: connect the coaxial cable from the antenna to the device, add batteries, connect to a power source, turn the antenna until the meter is at full power, then turn the knob on the device, until the meter is halfway, and then point the antenna. brings the counter to full strength or back to ten. There's also a beep to let you know when you think you're getting a good signal. From the very first connection, according to Antennaweb.org, the beeper and meter went into overdrive when pointed in the wrong direction. I moved the antenna to different locations and the meter and horn stayed at full power, turning the knob down both stayed at full power. So a crappy review for a crappy product.
