    This just happened to me. Unbelievable. The cable guy straight out said "you must have grow lights in your home. If the problem doesn't stop we will have to refer it to a different agency!"

    There was an old cable line right next to my ballasts that wasn't be used. He took it "offline" and said that should fix the problem.

    Crazy.. I knew I couldn't have been the only poor bastard this happened too.. crazy.

    I've since learned that what other posters said is right on... the problem isn't the ballast.. it is the exposed cable wire in the same general area of your ballasts... that wire picks up the RA from the ballast, gets in the loop, and gets the Cable Dicks at your door.

    Been a shitty 2 weeks for me. I have an empty tent in that room now and had to cram them into other tents (only lost 3).

    Do you think since he took that cable "offline" I should be good? My hydro guys had an RF blocker you can buy also. I'm about to get 2 magnetic ballasts for that room and call it a day. :(

    Had my cable discount. Cable guy said every night my blocks cable would mess up? He also said they, spent a month tacking the problem.

    Had a loses cable wire. Which was the cause. Crazy

    Yeah my guy said he spent about a month tracking it to me too. Insane man. Who would have ever thought.

    Haven't read the whole thread yet, but can't you just make a tin foil hat for your ballast?

    A tech came by my house, and my area was a curtain away from the modem. Apparently a splitter was bad and was ruining the signal for the neighborhood. I run a magnetic ballast, but still, I know that feel, bro.

    Copper box shield for the ballast. Expensive but it works.Then you have to cool the thing. Tin foil is not even dense enough to stop the waves.

    You had this problem with a magnetic ballast!? Fuck me.

    I would call BS on this to the cable company. It's the bandwidth that SOME digital ballasts interfere with and usually that relates to the router the customer who's complaining has. They would be fishing.

    They said it was a splitter. Or not even, it was a coupler

    The paper I posted shows there are far more digital ballasts around than just grow lights. They need to shield their own shit better. Supposedly there is WiFi blocking paint. I have no experience with it. But I know with Fender guitars thin copper sheet lining of the pickup and control cavity and a piece backing the pickguard sure cuts RFI and 6-cycle interference. Hum in those single coil pickups. This was going on where I lived before north of Anchorage.

    Scary shit, thats another reason why LED's are the fuckin champ son!!!


    joking, I know the haters will lose their panties on that one.

    Totally agree with you. My tent is below where my cable comes in, in my basement have 2 splitters above tent with one open space on it. Run a digital and always had a problem, even when I capped off the open port I had in the one splitter. Made sure it was tight etc, new wiring still problem, even got a "shield" at the store to help. Moved tent to smaller room on other side of basement. Never fixed anything. Got my magnetic back out, no problem what so ever. I don't think I'll ever switch to digital until they start making them better with some kind of block built into it for the interference.

    I am an amateur radio operator and can drive around and point out possible grows very easily. Both of my ballast's generate a signal that can be detected a few hundred feet away. In other words I can drive down my street with my 10 meter radio on and as I pass my house I detect the signal then it is gone as I pass the next house.
    Most of that signal is using the cord between the ballast and light fixture as an antenna. Shield that cord and you will cut that signal strength considerably! That cord is where you would install a choke to trap that signal.

    Is the case with magnetic ballast too? If so what's the best way to shield the wire?

    ButchyBoy Well-Known Member

    The magnetic ballast's aren't as bad as the digital ones. You can use a hand held am radio tuned between stations to check for the RF signal or a CB radio if you happen to have one. The best way to shield the cord between the light and ballast is with braided wire covering. It has to be made of stainless not plastic. http://www.cableorganizer.com/stainless-steel-braid/

    It really depends on the brand of ballast. I run an Apollo and a Thunder ballast. The Apollo is very dirty in regards to RF radiation and is the one responsible for the RF as I pass my house.
