The MFJ-805 Meter is an ultra-sensitive pocket-sized RFI detector used to track down RFI caused by radiating cables and wires. It will tell you exactly which cable is radiating RFI so you can eliminate it with a simple toroid or clamp-on RFI filter (not supplied). You can use it to find RFI generated by consumer devices, computers and high-tech office equipment. When you eliminate the RFI source, hash, birdies, whistles and transient noise miraculously disappear from your communications receiver.

The MFJ-805 also works with mobile installations. Ferreting out alternator has, ignition pulses and microprocessor noise on feedlines and power leads. Your MFJ Detector isolates cables picking up RFI and indicates when you've suppressed the problem. With a signal generator you can profile the radiating current distribution of antennas, radials, feedlines, ground systems and control lines. Simply clamp current transformer over suspected cable or wire to detect RFI causing common-mode currents. It is a compact 2.25W x 4.75H x 1D inches and fits in your shirt pocket. It requires a 9 volt battery (not supplied). This device is usable from VLF to VHF. The gain adjustable over a 50dB range.
