my computer causes interference...

Hi. Not sure if I'm in the right topic area, but I'm wondering if anybody can help me. My computer (actually the monitor) causes diagonal interference lines on a tv with rabbit ears for an antenna. This tv is actually in a room below me. I tried an expensive powerbar that supposedly filters out emf waves that might be travelling thru the wiring but it didn't do any good. I have a 17 inch monitor and I was wondering if the interference waves are travelling thru the air since monitors do have high voltages. If the interference is travelling thru the air can anything be done about it? Are there any stronger line-filters, besides specialty powerbars, that will stop wire transmission of emf waves? Any suggestions will be greatly appreciated.

You could always try one of these:

Might want to get the other person to pay for it though.

What make is that monitor and how old is it?

Hey--

Try using a Band Pass Filter on your antenna signal. This sounds like front-end overload, which happens to TVs when EMF is flying around. Amateur radio operators sometimes get complaints from neighbors because they transmit, the neighbor's TV has problems, and the TV companies don't build in filters.

The band pass filter will take out everything but the TV signals out of the signal coming from the antenna. It shouldn't cost more than $30 US.

Good luck!

 

Thanks for the info. My monitor is an Envision (made in china). It's power rating is: 100-240 volts, 50/60 Hz, 2.5 Amps.

 

You just have to notice that any interference is going to have a range, so if your computer is situated directly above where the person belows television is then it's currently in range so I suggest the cheapest method would be trying to shift your room around a little to move the computer from as far away as where the guys TV is
located.

Otherwise you have a few other options like placing a wiremesh or steel plate on the floor (this is likely to knock his signal out altogether though), Tell him to buy a proper antenna one that he can poke out at a different location, or buy a new monitor. (These all inccur cost)

 

Excellent suggestiong Stryderunknown. I run a coax upstairs to where I place our amplified broadcast antenna. I commonly don't have the case on my computer upstairs, just above our major TV watching location and still find not problematic EMI even though I have two large monitors in operation and often two computers.
