Can a amp kill a cable box

[Deleted User 30222]

I've noticed over the last 2 days that when i have my amp on, my computer keyboard and a cable box go dead. Now the cable box is in the next bedroom to my antenna. My keyboard is down by my radio. And the keyboard is not wireless. Anybody ever have something like this happen before. Or is it finally time to put my antenna up in the attic. Although hate to go through the trouble and have the same issues. Help please.

My computer and radio gear are all right on top of each other, and the DISH Network box is about 10 feet away...

Never had any wobbly lines in the picture on the TV or on the computer monitor....

But then again, no golden screwdrivers have ever been inside my radios either...



I don't know where you have your antenna...but it really needs to be outside...That's where I keep mine!

With the way you have it set up you are being bombarded with stray RF. First try a choke at the antenna, (5 wraps of coax about 4 1/2" diameter) right at the feedpoint. You can try snap beads (type 31 mix) on the USB cables for the keyboard and mouse, it takes 6 for 27mhz. Last, everything needs to be grounded. I'm not saying all these will cure the problem but might help eliminate some of it.

I have a rf choke at the antenna, so good there. I will try the beads today. As far as grounding. Where my main water pipe comes in the house, there is a grounding rod right next to the pipe. Can i use that for grounding. Or will people get Electrocuted while showering.

PS: Should i also put beads on the cable box. And they would go on the power cord...correct?

I use the water service line as my ground for the stuff in the house, it is copper pipe all the way to the meter, about 100ft. I connected the water pipe outside to my grounding system which is eight 8ft copper clad rods drove into the ground in various places around my house, all connected together with a copper wire about a 1/2" in diameter. I keep the electrical ground separate from the electronic ground but they do cross paths outside.
As far as the cable box, look at the way the coax for it is ran, should have a ground/surge arrestor hooked to it, a couple of snap beads right at the box wouldn't hurt, check to make sure it is the box and not the TV.

Ok, have my radio and amp grounded to the water line. Now have beads on the keyboard cable. Will put beads on the box in a bit and test it all out.
