    Not really sure if it's working or not. May be my error. Still trying to get a noticeable difference in noise.

  • I think it's okay

    Not sure that the RF Choke helped, but it certainly didn't hurt! For about $10, it was worth a try. Seems to be made solid and was certainly easy to use. No extra noise, just not sure that it reduced the noise. Worth giving it a try if you are having issues.

  • No Rockin FM radio in church!

    Our church has drop mics over the choir on 25' cords. They (the cords thought they were antenna) in those quiet moments when the preacher was making his point during the sermon - the PA could contribute the local crankin FM station. SO 1. unplug 3 prong mic 2. plug RFBLOX inline 3. Problem solved IT WAS THAT EASY - affordable fix, easy fix, nuf said.
