problem with neighbors wifi antenna open original image

Hello!



Few days ago my neighbor set up wifi antenna on his terrace.



Here are pictures, photoed from street:

And this pictures are photoed from my appartment, about 10 meters from wifi antenna:

The question is, is it safe for me and my family to live in our apartment due to potential exposure to electromagnetic radiation.



Should I ask him to move it to the roof?



Thanks for a help.

There's nothing you can do to stop EMR from hitting you and your family.

It's everywhere, cell towers, TV & radio, Wi-Fi, even the sun.

Chances are your microwave leaks much more 2.4 GHz radio waves than you are exposed to by the antenna next door.

NjamNjam hath wroth:

I can't tell if the dish is aimed at you or whether it's pointed elsewhere. That's a 24dBi gain dish antenna, which redirects almost all the energy in a very narrow 8 degree or less beamwidth in front of the antenna. If you were in this beamwidth, I would worry, depending on distance from the antenna. However, if you are outside the beam, including both above and below the beam, you're quite safe as there's hardly any RF in those angles. In fact, such a high gain dish antenna is the safest of the assortment because all the RF goes to where it's suppose to be going, and very little gets sprayed around the neighborhood.

I can grind some numbers on exposure if you want, but I need to know distances and angles.

Using the above calculator, a 24dBi antenna, in the area of 20ft away, with a 0.100 watt transmitter, you're safe about 2.4ft away. That's the worst case, where you're in the 8 degree beamwidth. To the side, there's MUCH less RF.

You have basis to complain about having to look at his laundry drying, for sure.

Yep. Laundry drying is dangerous. This happened yesterday while I was having lunch next door.

How to turn a laundry dryer into a barbeque. However, I don't think drying your laundry on the neighbors dish antenna is a good idea.

Well, in the meantime I photographed floor plan of my apartment (red color) and neighbors apartment, and calculated angle (16 deegres) and other dimensions.

Here is the picture with floor plan and dimensions:

Sorry, but I am new to this, and want to be sure.

Thanks for your help.

Are you at risk from your microwave oven? There is health risk from the radiation off the antenna. For starters the power is not high enough to be considered dangerous.

Well, I dont have microwave oven, cause I prefer tradicional cooking.

And yes, I know that there are all kinds of EM fields all around us, but the source is allways far away, not 10 meters from my apartement, aimed almost to my windows. Maybe I would not say anything if the dish was aimed somewhere else, but as you can see from pictures, this is very close to my windows.

I am trying not to be too paranoic, but want to know scientific truth.

I am in the wrong business. If I wanted to be rich I would be your shrink.

Hi, If you REALLY worry about things like that, only place for you is cave in the wilderness. Even there there will will EM wave floating around.

Hmmm, How about electrical wires inside your dwelling? They are not far away.

Nothing wrong with that.

You would be surprised to find out how close you are to various em fields.

And again, the low power out, makes it a non issue. Now if this was a cell site or some other high power site, you would have a valid concern.

It has been proven not to be an issue.

There is no evidence either way. I'm not aware of any scientific research that concludes that there is or is not a risk in such a configuration / situation.

Only you can decide. What would make you feel *comfortable* to continue living there? If you will always be thinking that the radiation from the antenna is causing some concern, that's not good, regardless any scientific evidence to the contrary.

As a neighbor, maybe he'd be willing to move it just at your request. Ask him.

Good luck,

If you want to know the numbers, you could buy an inexpensive RF field meter. That will tell you relative strength of the electromagnetic radiation in the RF band. You could measure RF strength at the other side of your condo (to see what the normal "background" strength is, and then measure it in the children's room, for example, to see if there is any increase, and if so, how much.

Here's one example:

It's US$145.

Maybe your neighbor already owns one. He might take readings for you to help you understand the numbers...

Where is your property located? It looks like you have a nice view!

Good luck, Dave

Thank you for your help.

That's a really nice looking dish antenna, could you ask him where he got it and how much he paid for it... ? Also could you ask him what kind of AP he uses, and what kind of distance he achieves at what singal levels, etc ?

TIA.

Here's a nice 21dbi dish. The "nice" thing about it is it's weight of less than 2 pounds (1kg).

It's also quite small - 60 x 45 cm
