radio tower in Likely, CA

I know plenty of old time repeater owners. The story is mostly likely crap.

They probably smoked ;-)

No.

There is no known mechanisum that would explain how radio waves can cause the effects listed in the link. I have to believe that if there was anything to the link between radio wave and sickness then there would be a ton of 'smoking gun' studies proving it. Despite what you may have heard or read about radio waves cauasing cancer *Not* One* of those studies has ever shown numbers more statisticly significant than random noise or been able to be duplicated by other reaserchers. Radio frequency waves have no demonstrably proven effects other than heating, they are not ionizing radiation such as emitted from nuclear materials- they can't cause any kind of organ failure unless you talking about fried liver.

While the picture looks impressive with all those dish antennas there is in fact very little radiation emitted from them except to the front. Government standards are very conservative for people working in RF fields, something like 1% of the level that produces any sort of observable effect, and thats a fration of a percent of the heating effect you would feel from simply sitting in front of a warm stove. If the levels are exceeded there than the complainents might have a case for an un-safe work space but I have a very hard time believing the levels would be anywhere near anything you could feel, never mind actually dangerous. As for some of the conditions listed such as 'radiation anorexia' thats something that appears to be tied to radiation treatments for cancer, & yes, that *is* ionizing radiation.

The writer may very well really be sick, but I'd be looking for other causes rather than trying to blame something, which from everything we know about how the universe works, isn't responsible.

Or invoking conspiracie theories when no one agees with them.

I'm not questioning the research, I just find it really odd that entire families would suffer symptoms. Something in the soil dust, perhaps?

"In memory of Mary Smith, Likely Mountain Lookout resident for three fire seasons. 1997-1999. Passed away of cancer early summer 2000." After only three years?

Do towers in the Middle of Nowhere operate at higher power than typical cellular towers in a city?

For the record, I stumbled upon the site while looking for tiny towns in the mountains to take a vacation. Likely, CA seemed interesting...

The funny thing is cellular tower are designed to be low power. You want to reuse the frequencies in other cells (so called channel reuse). Digital cellular (and they are all digital these days) has timing issues that prevent long distance operation. More so with GSM than CDMA.

Those symptoms sound lot like what I went through after a VA doctor ordered me to stop using any salt in my food. The diabetic Neuropathy went from a slight tingle, to pain so severe I couldn't use my right arm. I had diaherea so bad I couldn't leave the house most days, My vision was very blurred, I had constant headaches, and my tinitus was so loud I could barely hear. i was losing weight, as well.

How were their families affected, if the two observers were up their by themselves? How did they get any measurable RF from the radomes that all point away from the tower? I don't see any reflectors for ground based antennas, and the building on top appears to have a metal floor.

If the site had RADAR, or she was frequently in the front field of a horn or dish with 5 watts of drive, the cataracts would be believable. I don't know about the rest, but cataracts are a microwave work hazard.

Steve Roberts

Why would they have a RADAR on a fire tower? None of those antennas are movable, so RADAR would be fairly useless. They look like old telephone microwave relay links that are fairly low power. Maybe ten watts, judging from the equipment I've seen. Leakage of any RF power would be seen at the receiving end as a reduced level, or a higher noise floor.

The only high power microwave communications system that I know of was the 'White Alice" network which was built in Alaska, decades ago. It was the first 'Over the Horizon' microwave relay. It was built to provide communications between the military bases, and any city or town close enough to a terminal.

So is bright sunlight. They spent all day looking out the windows looking for smoke.

There are "hot" mountain to mountain links in the Nevada desert, and private radars are all over the place for TV stations. Yeah, I know its not likely, but UHF and 800 mhz paging is sometimes 500-1000 watts, and some cell systems do have hot erps. Since this is one of the few sites I cant find aerial photos on, lets give them a little benefit of the doubt. Would you go up there every day in that field?

Steve Roberts

From what I see, there is less chance of RF exposure there, than most places I worked, so yes I would, other than the fact that I can not climb ladders, or go up more than a few steps anymore. (Being 100% disabled stinks)

I've worked sites with 2 MW RADAR, (Carin Airfield, Alabama) and 5 MW EIRP UHF TV, (Orange City, Florida) so sure. Those antennas are not 800 MHz, they are much higher. I have worked in RF most of my life. I have even climbed inside a live TV transmitter to make repairs & adjustments while it was on the air.

was part of the last company I worked for.

Something wrong with their house, toxic mould? outgassing of building materials?

yes, but less often.

I think she said families were encouraged to stay at the fire tower with the employees, thus they were also exposed to the same "radiation".

At the tower site, or up the tower? There is a huge difference.

Wow. A lot of mis-information in this thread. If you really want all the corrections, email me and I'll go through the trouble.

The short answer is: No. This complaint is not related to non-ionizing radiofrequency radiation exposure.

This has been beat to death over the years. There is nothing here. For suggested reading, Google the "Lookout Mountain" EME case in Denver 5 or 6 years ago. Also, Canyon Area Residents for the Environment (CARE), same situation.

Tower climbers do face one very serious related problem, however. That is: startle reactions from localized high RF fields (while on the tower). If they are not properly tied off to the tower, this can be a source of many ugly accidents / fatalities (from the fall).

By law, cellular base stations can radiate up to 3,500 watts ERP, though many (if not most) are lower than this value. Typical cell sites use high gain (~ 12dB - 14dB) sectorized antennas.

Cellular licensees are responsible for compliance with RF exposures (both worker and general public), and thus will take appropriate steps to restrict access to the antennas. Also, typical cellular tower heights are sufficient to protect ground personnel exposures. About the only situations for cellular/PCS (all modulation types) is for roof-mounted antennas where someone could physically walk in front of the antenans, and antennas mounted on billboards (outdoor advertising). Plus a very few other, unique situations. Otherwise, cellular exposure is harmless*.

Except that, lately (last few years), there seems to be some evidence gaining regarding nodules in the inner ear related to handset use (not the towers). I dropped off that conversations a while back, but if there's anything to it, I would expect to see it listed in the next revision of ANSI C95.1

Also, remember that cellular in the US operates in the 850 band, and PCS in the 1850-1990 MHz band. (AWS will be just below that). The human body does not readily absorb any of these frequencies. (VHF - particularly FM broadcast band is a much greater concern.)
