This RFI kit is specifically designed to cure most sprinkler control systems triggered by Radio Frequency Interference problems. The kit contains a large (ID = 1") snap on filter for the AC power Line protection and snap on ferrite beads for 4 sprinkler control lines. (Multiple control lines can go through the same ferrite filter) The ferrites are selected to eliminate RFI from 1 to 300 MHz. The ferrites are easy to use, don’t require modification of the protected equipment and work in almost all cases.
If you need control line filters for more than 4 control line "bundles" order part # FSB31-1/2.
Also make sure you connect a good RF ground to the transceiver ground post.
Note to Flex Radio users: Use snap on ferrites for firewire cable, speaker cable and mic cable, Ring ferrites for Antenna output and DC power.
For additional RFI suppression, use a feed line choke at the antenna to suppress common current on the coax feed line – see our store for feed line choke alternatives for use at the antenna.
If you use a linear amplifier we have RFI kits for linear amplifiers that help suppress RFI in your shack or in your neighbor’s house.
