I'd bet you wouldn't let them put one on top of your kids school ... Why not? Microwaves are nothing. Kids are exposed to a much more powerful and dangerous type of radiation each time they go outside the building, one that is virtually guaranteed to cause severe burns and even cancer on overexposure. It's called sunlight. -- Transpose hotmail and mxsmanic in my e-mail address to reach me directly. |

You still radiate any kid in the car with far more RF power from your cell phone than they'll ever see in a normal environment. It doesn't matter how close they get to the antenna tower. And for microwave antennas on a tower that beam goes over the head like a searchlight anyway. SBH Sure it does, for a dish maybe but a panel? You rarely see dish transmitters or receivers on mobile phone masts. And the Tetra system used by the police and ambulance has NO directional type masts. One Tetra I looked at recently was next to a school. http://www.whale.to/b/tet.html I'd bet you wouldn't let them put one on top of your kids school like this cancer scientist http://www.whale.to/b/tetra1.html Of course they're directional. Any fixed antenna system benefits greatly from managing the dispersion pattern simply because it gets better coverage within its range and less interference outside it. It's just good RF engineering. Dates back to the 30s and 40s. Wait a few decades and Scudamore may even catch up to the period. Ha. Scudamore wishes he'd been born several hundred years ago, back when they really understood healing. -- David Wright :: alphabeta at prodigy.net These are my opinions only, but they're almost always correct.

"CWatters" wrote in message - Hi John, Yes panel type can also be directional. For mobile phones usually several panels pointing in slightly different directions are used. Oh really, I've read an independent expert on microwaves and I din't see any mention of that http://www.whale.to/a/trower_h.html Nice try. |

Can someone who knows more than I about microwave radiation confirm? (If nothing else, the author seems clueless about ionizing vs non-ionizing radiation.) -- David Wright :: alphabeta at prodigy.net These are my opinions only, but they're almost always correct.

Have a look at a picture of an Aegis cruiser and tell us that that honking panel on it isn't useful because it's not directional. Knowing Scudamore, he'll prolly insist that the Aegis program is part of a Government conspiracy to make us think that cell towers are directional. -- A:*Because*it*messes*up*the*order*in*which*people* normally*read*text.

"john" wrote in message ... "D. C. Sessions" wrote in message ... What direction are cell phone panels pointing and radiating then? I'll give you another hint, field strength is not necessarily constant within the radiation direction even though one may be equidistant. |
