Again, anti-radiation people...

I suggest that you read this letter, then think about the following points:

The real problem is that the people who install this equipment have the nasty habit of hooking up a much larger antenna to extract a greater range. This is really danger-ous.

How is it dangerous? Greater range is dangerous? Give some studies please!

The second situation is to do with the characteristics of microwave antennas. Generally, the smaller the diameter of the antenna, the higher the frequency and the less control there is over radiation being spilled outwards.

What this means is that the dish itself radiates energy from the sides and this is known as the sidelobe performance. If a one-metre dish is hung inappropriately on a building, the sidelobe radiation can spill over into the rooms to the side and below.

In one case, four of these high-gain WiFi antennas radiated into three condominiums and caused endless health problems for the occupants.

Please provide some technical specifications on the uncontrollable side lobes of high gain microwave antennas. Please also provide the case where 4 high gain WiFi antennas caused "endless health problems for the occupants". Otherwise, stop sputing nonsense.

There was a prior situation on this concerning Melbourne University where the top two floors were emptied due to an unusual number of cancers. All of the equipment met regulatory requirements.

Please provide the reference to this incident, indicating the link between the RF emission and the incidents of cancer. Otherwise, don't mistake correlation for causation.

Seriously.. why so scared to progress? Remember that by the time the radiated power from antennas reach you, it has degraded to such miniscule values (0.0000001W!) that it's basically harmless. If anything, you should be more concerned about the radiation from your mobile phones when you're talking for hours!
