Low Pass Filter 27/586 (3-30Mhz) 500 Watts Max

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!.

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.

My HD antenna 25 ft away from the sirio 827 antenna. Everytime I keyed my mic, it would cause TV interfaces. This solved the problem, now my wife is happy. I didn't really want to move either antenna. The cable management is a lot of work.

I use this on my CB Base radio and it is quite effective. Nice build quality (inside and out). The small size is a plus. (Note: Because of the internal design, both SO-239 connectors are on one side. I had to use a right-angle adapter to connect this to my radio and have space for the coax to my antenna.)

But this one seems to work quite well. Intended to pair with small RMItaly amplifiers that DO NOT have built in bandpass filtration, I.E. no band switch, just, you know, on-off, ssb/am, preamp on/off yes those model amplifiers. I would not run one of those without one of these. Enjoy.

I installed this for peace of mind that I was not interfering with nearby electronics. I did not notice any loss in watt output which probably means that my radio did not have much in the way of unwanted harmonics. If you do notice a drop in watts, it probably means your radio needs aligned.

Raised SWR making it unusable

Can't tell item is in circuit, no SWR problems after installing
