Any history of controversy in the LR community over these?

The short answer is the biggest problem you may encounter is front-end overload or de-sense on your stereo, depending on your relative position and distance from the towers.
You can stop there......or read on.
The F.C.C. and OSHA set standards for allowable RF exposure. This is measured by a field strength meter at many points, and by F.C.C. rules, the owners of the transmitting equipment must be in compliance.
Again, not knowing what class emissions are being transmitted, it's a little hard to even speculate on what kind of an RF field could be expected. Normally you may have a television transmitter or two and some cell phone antennas, so you're roughly talking about 50-900 MHZ there. Throw in some microwave relay towers, and you're probably up around 5 GHZ.
All the above are "line of sight" waves (with the exception of tropspheric ducting) and tend to be in varying straight line radiation.
Add to the fact, that maximum attentuation, around 30 db, is found straight *under* the transmitting antenna, you're talking minute amounts, if any, RF from those transmitting antennas.
Now, understand, that you are being absolutely bombarded with RF as you read this. It's coming from your computer, from the monitor, from your television, your stereo receiver, etc.
Try taking an AM radio, tune to where there's no station, and move toward electronics, or better yet, a light dimmer switch.
Even if you move out to the hills, beyond "the country", where the red dirt roads start ceasing to be, like some of us, you can stand on your "I'm one with nature" hill, and you have radio waves passing through you from broadcast transmitters, radio communications, microwave relays, and cell phone towers.
There has never been any evidence that these RF emissions, unlike 60 hz EMF fields from high power lines, have any detrimental effect on the human body.
Research has shown changes in the human brain following cell phone use, and a recent study confirmed that students had a slower learning rate for about an hour after using their cell phones, which is a variable output but max's out at .6 of a watt, but we all choose to use them anyway.
So, KCMFTI, the truth is, you are going to have much less exposure to those towers, living at the foot of them, than you are 5 miles away, and there's been no study that I'm aware of linking normal field RF exposure as a carcinigen, so if you can put up with the eyesore, it'd probably be as safe as you can be.
