Low Pass Filters

[Little Reb]

I just got back from my local cb shop and got all my stuff i am gonna need to put my A-99 in the air. However the guy at the desk told me im going to need a low pass filter so i went back to look at theres and they wanted 50 dollars for one that looked really cheap does anyone know what this thing does and if i need one? Also were to get a good quality one at? all probolly never run over a 1kw in the coax so i dont need a real heavy duty one just a good quality low pass filter. Thanks and God Bless

I run a low pass filter on all by base stations. Indeed it's designed to reduce/eliminate harmonics...which is the main cause of TVI/RFI. If you plan on running an amp, it's a good investment. I think I paid $75 for mine years ago...and I think mine's a Drake or something.

Hope that helps some.

Drake is a good brand. Look for an MFJ one, they're ususally cheap. I don't have one myself, but I probably should.

Ive read before that if you don't have any problems on your own TV, its unlikely to be causing probs on any one else. But I have a question about wether or not the same problems occur on all types of TV reception, i e satellite dish, cable, Aeriel,........ are antennas more prone t getting bled on than dish? Just curios........

if it doesn't cause interference on your tv, then you are not responsible for fixing anything with your transmitter, because your neighbor's TV has the problem.

I believe that its only RF reception IE: TV antennas/ rabbit antennas on up. Dish and cable are closed systems on different freqs. Other amplified sound is susceptible though, stereo, surround, etc.

Yea, typically that is the case. Cheaper quality stereo equipment, speaker wire, etc. can also contribute. Another thing too is loose connections on the cable TV coax. Typically just because you aren't bleeding on your stuff isn't a guarantee you aren't on the neighbors. However, it helps alot to show the neighbor you don't bleed on your own stuff.

Some neighbors though have "antennaphobia" and see any antenna as a potential problem because they don't like them. Knew a Ham once that had that happen. Went home after hearing the neighbor complain, waited a few minutes and asked if she heard him bleeding over. "Oh yes!" she said. He never even turned his tranceiver on.
