MFJ-915 RF Isolators are 1:1 ferrite chokes designed to be placed in line with 50-Ohm coax. These RF Isolators are effective from 1.8 to 30 MHz at full SSB legal power. They were designed to improve the performance of all amateur stations, fixed or mobile.

MFJ RF isolators reduce or eliminate stray RF often found on coax shields. If strong enough, this current may cause RF burns or other problems with electronic equipment in ham shacks and vehicles. Stray RF also results in a loss of radiated power from the antenna, which will cause a reduction in radiated signal strength. Use of MFJ-915 RF Isolators will increase the efficiency of all HF amateur stations.

These RF Isolators are made up of 50 Ferrite Core Beads, placed onto a 13-inch piece of RG-303 coax. The coax and SO-239 connectors have PTFE insulation which extends the life of the product. The entire assembly is enclosed in schedule 40 PVC pipe for maximum strength and protection.

If you have an RFI problem in your shack, then one of these MFJ-915 RF Isolators, now available from DX Engineering, may be the answer you need.

These work great! I put one on the feed to my SDR Play and one on the feed to my ICOM 7300. Both improved noticeably. I'd put one on every HF feed.

Easy way to keep RF out of the shack!

If you have a G5RV, or any variant of, this is a must. A little expensive for what it is, but quality made and does what it's supposed to do. No more RF hum or RF bites!
