Review: Helps Stop Vehicle Interference - Works great and stopped my CB radio and amplifier from interfering with my ABS and Stabilitrak system in my truck. 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!. ## Features - Low pass tvi filter - 50 ohm, 3-30 mhz range , 50db attenuation at 54 mhz - Input power 300 watts input power ssb: 500 watts - Insertion loss: 0.5 db - Mode: am-fm-ssb-cw , connector: so-239 ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0075S8L0Q | | Antenna | Radio, Television | | AntennaDescription | Radio, Television | | Best Sellers Rank | #2,750 in Audio & Video Antennas | | Brand | RM Italy | | Color | Black | | Compatible Devices | Television, Radio | | Connectivity Technology | Coaxial | | Connector Type | SO-239 | | Customer Reviews | 4.5 out of 5 stars 83 Reviews | | Global Trade Identification Number | 00670541232590 | | Includes Remote | No | | Item Weight | 0.56 Pounds | | Manufacturer | RM Italy | | Mfr Part Number | rm_27586 | | Model Number | rm_27586 | | Tuner Type | am-fm-ssb-cw | | UPC | 670541232590 | | Unit Count | 1.0 Count | | Warranty Description | 1 year | ## Product Details - **Brand:** RM Italy - **Color:** Black - **Compatible Devices:** Television, Radio - **Connectivity Technology:** Coaxial - **Connector Type:** SO-239 ## Images ![RM Italy Low Pass Filter 27/586 (3-30Mhz) 500 Watts Max - Image 1](https://m.media-amazon.com/images/I/51xFt7uc7sL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Helps Stop Vehicle Interference *by K***S on October 16, 2025* Works great and stopped my CB radio and amplifier from interfering with my ABS and Stabilitrak system in my truck. ### ⭐⭐⭐⭐⭐ Works great, great Price! *by A***B on January 28, 2020* I use this in conjunction with a DF3000 low pass filter.
