Re: Topband: Wireless Internet RFI Issue

["Tom W8JI" <w8ji@w8ji.com>]

That almost always is a switching power supply issue. The normal mode of 
excitation is differential between the power mains and other cables. My 
neighbor's system bothered me.
The BEST solution to this is a lightning protection type outlet strip that 
(if it does not have them) you add capacitors to. I used a system that had F 
connectors, eithernet, telco, and power.
This is thousands of times more effective than throwing beads at it and just 
hoping common mode impedances are so low the beads do something.
