Suppressed, my RFI worked well. I am glad I purchased them from Palomar. Thank you.
DJDonald J.Verified buyerEVERYONE needs this! I use FT8 a lot, and I live in a city, so I have a lot of noise around. I tried the amazon special to save money, but literally did not help. I bought these after some research and testing. Literally boosted my contacts by at least 26% via Ft8. This is a 4 week average increase. These things really work!
BRBrad R.Verified buyerSolved my RFI problems which made 20 phone hard to use on high power. Highly recommend
RGRobert G.Verified buyerGreat price and really does work
MLMarilyn L.Verified buyerEZ to install on Cables . Had RF before that shut down computers is no longer an issue . Tech Support available was a Huge advantage . Appreciate the help to make my Shack efficient . 1:1 cable was a game changer against noise . Will buy any further needed Ferrites from Palomar Engineers .

I would like to block RF on my two incoming circuits to my shack and I am looking at this approach. Crud. I can’t seem to be able to paste a pic. Can I send an email. I have two kits in my shopping cart and need a bit more.
yes send email to sales@palomar-engineers.com
Typical user comment:
The filter was quite effective. Was surprised that it actually reduced the noise level more than the signal so S+N/N improved by 1.9 S units. Bill
