Megavolt Transmission line within 300'

[topgun1986]

I am looking to purchase some property for my new home and would like to build an antenna farm on it (shortwave up to UHF). The property I am looking at purchasing sits up pretty high in the county but there is a megavolt? transmission (unsure of actual voltage) line running on one side of the property, roughly 300' from my antennae location. I hope to find out more specifics this week, as far as actual voltage this line carries. Should I be concerned about this for an antennae farm?

There's a good reason no one else is living there!

Yes, be very concerned about noise, mostly on HF. If you plan on any wire antennas keep them at a right angle to the power lines and as far away as possible. You might also try a portable HF radio at the property to see if its a total wipe out, which could help decide if its a bad place to live.

There are also potential health risks like leukemia from living too close to super high power lines like over 500kV and it all depends on the exposure levels and duration your exposed. Its one thing to be exposed to large EMF fields at work for brief periods but you spend a lot more time at home, so I would recommend getting some data on what EMF levels might be bathing the house your looking at.

You will find lots of info on the Internet about this with some saying there is no risk at all at any voltage or distance, probably from studies funded by the power companies. The World Health Organization is definitely attributing higher risk of some cancers and other problems from living in close proximity to high power lines based on many studies in many different countries.

Ok, now I'm worried, find another place to live and one that is better for your hobby. Don't buy it!

As for noise, it will be hit or miss. Best to run a few tests.
As far as health concerns go....

There's no good answer to this.
Those who dislike power lines and wear a tin foil hat will tell you power lines makes your penis fall off.
Those who own power lines say they are safe.
Those who are the middle man don't really know but can make a cool YouTube video and ask you to like and $ub$cribe.
All I can suggest is any research you do, consider the source.

Here's a link to the American Cancer Society and their take on power lines : Power Lines, Electrical Devices, and Extremely Low Frequency Radiation

Some may argue they are not the ultimate expert source on this matter, but probably one of the better sources for folks in the USA.

Don't forget non-ionizing VS ionizing radation. There's a huge difference.

go at night and bring a fluorescent tube. if it lights you might have some radio trouble.
i have head of some folks running small antennas to one end of the tube and the other end to ground for free lighting.

skip to the 10 minute part.

Waking a old topic, but originally from south florida with high humidity and salt in the air. You should hear those lines popping and crackling with your own ears, never mind trying the HF freqs.

That's not the lines that are crackling, it's the leakage across the wet and dirty glass or porcelain insulators. They rely on rain to keep them clean and dry out later - perhaps.

Personally I would.... RUN!

This place sounds familiar.

HF dipoles and other antennas near high voltage lines:
Where I work there is a 367kv feet away, its not noticable and other noise sources predominate.
When I drive a highway there are some 367KV about 20 feet above the vehicle, yes on AM band the buzz will get into the AM station for about 50 to 100 feet when driven under.
The photos show a tower and insulators behind the back yard. They are quiet unless old insulators are cracked, and you can check it with a portable radio just tune to WWV or an am station and walk under it.
As far as locating a bad insulator or open ground thats best done on UHF with a good AM receiver, to pinpoint the pole. Most power companies will work to eliminate a bad insulator or bad ground.
Just report the problem and they have EMI guys that will come out locate it and send a crew to it.
However if there is noise on the line it could carry for a long way down the line, usually the worst noise sources are cheap power converters with the EMI components left out(cheapies from Asia) these have to be found and replaced, such as PC adapters.
