Delta V ECM - Differential detection

Delta V ECM measures the difference in field strength between its two antennas. By examining this gradient effect Delta V ECM responds positively in favour of local signals whilst tending to reject stronger signals originating from outside the search area. This makes it ideal for locating radio bugs and basic RFI/EMC testing.

Wide band performance from 20 MHz to over 4.2 GHz with even response

Dynamic range greater than 50dB. Small, portable and easy to use
