Review on 📡 DefCon DD1206 Professional RF Bluetooth, GSM, WiFi Detector: DiscoverIt Digital Radio Frequency Hunter Sweeper by Andrew Webster

I had to get additional antennas as the ones supplied have too great a range. Antennas for the intended use are given the best sensitivity for the desired range and rejection of other signals. A wide band will do for starters, but you need the right elements to determine the location. We use matching antennas for all purposes, why don't you find them? The good thing about the box is that it has small inputs, making it easy to use external devices and whips.
