ERP is not the same thing as raw wattage 'into the waveguide'. It involves antenna gain and the transmitter output can be much smaller. Many TV stations saw huge reductions in energy use after the digital transition. With analog, you needed a really strong signal to look good. With digital, y

Based upon the number/type off cell channels on the tower it looks like it can be a total of 30,000-75,000 W per tower at peak use. Multiply that by x number of towers and you can see it adds up fast. Throw in a couple of 250,000 to 750,000 watt Doppler weather stations and a few FM and high def

I think you are right, I was thinking FM broadcast stations How far are you from the nearest FM radio tower? Those typically put out 100,000W. Cell Towers Although the FCC permits an effective radiated power (ERP) of up to 500 watts per channel (depending on the tower height), the majority of cell

The figure of 100,000 watts for a cell phone tower seems a little high. The most plausible figures from the web seem to be up to 500 watts if they are covering a large area, or somewhat less if it is a small cell in a city. Nigel On 12/12/2013 19:21, leaking pen wrote: Waldo anyone? On Thu

Guys, I think Doppler Weather and Military radar pulsing 750,000 to 3,000,000 watts 24/7 into the atmosphere is potentially the worst of the offenders. The NEXRAD Doppler weather towers cover a 150 mile radius. In Sitka, Alaska, within that 150 mile radius, the Yellow Cedar trees are slowly wast
