i got a neighbor about 60ft away im coming over his tv set he has a dish up but i dont think he uses it anymore.as for my setup i got a uniden grant xl with limiter intact,imax2k around 25ft@feedpoint, 9ft copper grounding rod,#6solid copper wire wrapped around the bolt holding antenna 2 mast.i did notice that normally i use a tunerplus3 but if i change it 2 a unamplyifed mike i tried a asatic 636 the tvi went down but not away.i did have radio/powersupply/meters all grounded but made no difference at all,so i did undo that cause kids were tripping over all those wires,lol

I take it your only running 4-6 watts.
Where's your antenna mounted? On house,
tower,tree ect.? Type of coax?
You could try using a good TVI filter.
High pass filter installed on TV.
Raising your antenna up another 10ft or so.
Move location of antenna.
GPK for Imax.
Choke or ferrite cores installed up near feedpoint
of coax.
One ground rod will not do much in the event of a strike. But, it is better than nothing.
Find out exactly what's going on with your
neighbors consumer product (TV). How your effecting it. Good Luck

Different consumer products ect. ect. ect. |

What happens to the TV? Does it happen on every channel or only CH2 and CH6? |

two answer roadwarris questions im running 50ft of lmr 400 coax.i bought a tvi filter off an internet site but it was a cheapy only 20bucks a workman did absolutely nothing.as for whts it doing to the tv in the am mode the carrier alone makes tv have alot of lines then my audio comes thru if i use a poer mike.on ssb mode i key up the mike and thats fine but when i modulate the tv brings up lines kinda like on an oscope thats gives a general idea.ive been looking into braided copper wire told it works a little better.as far as alumin antenna im putting up a maco103 this spring hopfully

It sounds like TVI and not just strong signal interference. As long as you're running legal you're in the clear and it's his responsibility to resolve the problem, but it's a nice gesture to help.
Use the low pass filter and have your neighbor get a high pass filter from Radio Shack for his TV - they're $6 (15-579).
Grounding the TV is a good idea too, but the way most TVs are made today it's difficult. About the only place you can attach a ground is the F connector antenna jack. |

Is the Modulation Limiter still intact
on that radio Dale?
LMR 400 is good coax.
Braided wire makes no difference. A large
smooth surface should be used for lightning
protection grounds.
Or was you talking about your radio (equipment)
Rf ground wire? |

One thing i found here that helped was to
raise antenna to 36-38 ft to feedpoint.
Sounds like you have a hostile neighbor
problem. In that case no matter what you
do, you will get blamed. Fix things on your
end and that's all you can do.
I take it Dale your NOT running a Amp?
Mount the TvI filter directly into your radio.

I cause tvi on my neighbors tv also. Under a couple hundred watts is no problem but if I use much more than that its whats is called reciever overload. I have tried each suggestion stated above except GPK for my Imax. The only real solution for me is to move my antenna away from the neighbors house this spring. I should have known better when I installed it. If your legal power on the other hand I would stop worrying about it. Should be that much easier not to worry if the neighbor is impolite to you. good luck |

only major complaint i get(& have gotten since this neighbor moved here 14 years ago) is 200' +/-to, 1st, their RCA big screen with built in speakers, then they replaced it with a whole new 'theater system'. i do nothing to the pic on either, but BLAST through the speakers-loudest when tv is on, still loud when tv is off, & noticeable when UNPLUGGED from wall.
a 4 watt out of the box radio doesn't do anything. any dual final radio i've used, modded for power or not, including my S9, causes just as much interference as my 101e, ic735, & ar3500. i've witnessed it, & cannot tell which radio it is, 25 watts PEP or 160 watts PEP. for that matter, 600 watts PEP is also NO DIFFERENT then 25. but 10 watts does nothing. THEY had the cable company check & replace the wiring from the pole to the house, AND they PAID the cable co to rewire inside the house. the 110v wiring is to say the least, ancient. 2 wire, cloth covered, probably 50 years old or more. they also paid to rewire their den, to current code & redid the ground system. (they did all of this of their own accord, even after i assured them if it was a problem, call me, or i would do 95% of my operating mobile.)
i WAS grounded, RF & DC, caused NO interference to any of 4 tv's in my house, or any stereo. they witnessed that. which i guess is why they were so understanding. though, we still had the agreement, if i'm a problem, call me. i'll either shut down, or go mobile. has worked a charm for 14 years.
with NO changes to grounding, equipment, antenna, etc, one day, i raised my maco v5/8 from 18' at the feedpoint to closer to 30'. while i noticed little if any difference in performance-local, dx, noise, swr, nothing-they told me the interference to their home theaters' speakers suddenly stopped. ???? it now also took the 600 watts PEP to SLIGHTLY be heard through their speakers, & only with the tv on. the feedpoint was now at least 10' ABOVE where the cable tv line connected to MY house. maybe?? the interference was nonexistant for most of a year, EVEN when the polyphaser & GROUND were removed (do to damage) for a couple months. do to impending construction on my house(new, bigger radio room  ), i had to lower the maco back to the 18' mark. guess what? interference returned. exactly as it was-no different.
food for thought??? |
