## Description

Review: Small and works well - Stopped bleed over in the surround sound when on 20 meters. Improved antenna characteristics on off center fed dipole in the bands it’s designed for. Recommend for cmc fix.
Review: Works great, great Price! - I use this in conjunction with a DF3000 low pass filter. I live in close proximity to an Air Medic port, Fire Station, and Police Station and run an IMAX 2000 which is known to cause RFI issues. I have tried running this filter at different points in the coax in in different series to the other filter and have seen nothing but flat SWR. Im even seeing a slightly lower SWR at the radio with both filters connected in series. This filter has greater attenuation above 30 MHz but the DF3000 has two curves giving it more of a band pass effect. Together they work great. I have a TV antenna about 20 feet away from the IMAX and with no filters I get a bit of interference but with filters connected, I get nothing. Well worth it!.
