Power line Interference?

Hello All.

New to the forum but not a noob. I'm in Northeast, Ohio (Akron area). I do have a question though about overhead electrical lines and if that poses any potential signal interference issues. I have to move my 1000.2 due to tree growth (can't just trim the trees) and the only place I can move it to is a decent clearing but my line of sight shoots right through some overhead electrical and phone/cable lines. These are not high voltage kv lines but standard residential utilities (120V x2) probably about 30-50 feet above the dish. The 110 and 119 sats seem to clear them but 129 is smack in the middle of the lines. I have already moved the dish temporarily (pole in a bucket) and signals are good on 110/119 averaging upper 60's to upper 70's but 129 is in 30-40's. Is it normal in this area for 129 to be so much lower than 110/119 or could the power lines be causing an issue? Interestingly, I'm not seeing any pixelation or drop outs on the 129 HD channels, in fact we even had a pretty good thunderstorm thismorning and although all signals dropped somewhat, even the 129 sat into the 20-30's, I never got any rain fade. The obvious answer is then don't worry about it, but I just wanted to know if I should be concerned about the 129 levels before I bury the lines and set the pole in it's new location. Thanks.
 
Don't worry about your power lines; they would have to be thicker than I have ever seen (maybe Brazil?) to shadow the dish significantly.

Also, 129 is almost (if not totally) all 8PSK transponders, while most on the other sats are still QPSK. 8PSK transponders read lower, because we aren't really looking at signal strength, but rather a kind of inverse digital error rate. 8PSK has a greater error rate, and a greater error rate means lower reading on the point dish screen.
 
If it works, be happy. The line voltage will not cause interference but the wires will block a bit of signal just by being a material object in the LoS.

BTW if you have transformers in your neighborhood, as is almost unavoidable, the line voltage will be higher than 240 v at the poles.

Peak the 129 sat and 110. If you lose just a little on 119 don't worry about it. It will do just fine. Power lines are so thin that they don't pose any problems and the won't give you interference.
 
Ok folks, I appreciate the input. I'm not going to worry about it then. I'll just plant the post and be done with it. Thanks for the help.
 

Not just Dish

OK Dirt please respond...
