This is also kindof a shout out to anyone in the California Central Valley that frequents or lives in the Badger/Hartland area of the Sierras, who may have first hand knowledge of this. Now this may be the tinfoil on my head being a little to tight, but I ran into something interesting that, I'm pretty sure wasn't their before. In Cali, we have little to no snow right now in the mountains. I figured what the heck, gonna have some fun anyway. So I went to an area a lot of us frequent to hike, shoot, etc. I get up there and for one they have fenced off huge areas of access to the inner area we usually go to. "Sequoia National Monument" BS written every where. Gates in place to block access to areas we normally have had all year access to, even in the snow. That's the first thing that ****ed me off. So I see a road not blocked and I start to follow it. It stops at a gate that says "No Access, High Frequency Energy Area". No I don't have pictures, but I'm thinking of going back up for the day next week and exploring it a bit more. No government tags anywhere. Then someone on an olive drab dirt bike, with hard boxes on the sides, rides through and is eyeballing me the whole time. Didn't notice any weapons on him, just kinda weird. It just didn't set right with me. I have not been in that area for more than a year or so due to school and work, but I do know there weren't all the fences and signs, and we could travel way back in there and hunt, shoot, and hike all over. I'd appreciate any knowledge anyone who frequents that area, lives in the Badger/Hartland area, or anyone who has any knowledge of these kinds of areas has. The HAARP thing came to mind, but I think the area is too small for something like that considering what I've heard of the one in Alaska. Please reply.

With regard to the Electromagnetic Spectrum, RF, High Frequency = High Energy.

High Energy = Potential Biohazard.

Could be X-Rays for all you know.

First of all thanks for the response. But understand I'm a retard when it comes to this stuff. What does that boil down to ? Why would this be in a mountain area, approx. 2500 to 3500' elevation?

At one time, I desighned missile and bomb fuzes. One potential application was for a missile fuze.It was originally developed for extremly accurate space docking maneuveres It broacast at less than 1/2 watt (500 miiliwatt) It was at extremely high frequency. But very low power. The RF diodes were put on a diamond chip with a scanninig electron microscope. The diamond cooled the diode oscillator chip through mechanical vibration. These chips were made by a West Coast lab very near Pepperdine University.
They could be testing it for some classified application. It isn't necessarily danagerous, just claasified and that's how they keep uncleared people out. They may be testing it at high altitudes to simulate some chacteristcs.

 

[Justme11]

Can you call the park service or something?
That sign could mean a lot of things. (most of which can irradiate you and give you cancer. )

 

[LeftCoast Grower]

There was talk about closing a portion of that area due to some folks cutting parts of the redwood tree for furniture making.
Tree poachers...

Not sure if the sign refers to that activity.

 

[Wild Bill H]

It's not uncommon for people to put up bogus signs to protect "their road" or "their turf", etc. Generally govt warning signs have the agency's name on the sign. My bet is on bogus.

I've had kids climbing a tower and we put a fence with barbed wire on the top, kids dug under. Pushed in the gates with a car, just to get the red dome off the night strobes. We put up no trespassing sighs, add violators would be prosecuted, etc. Tried all sorts of stuff. what finally did the trick was a sign that said "Warning high frequency RF can cause sterility". Had no more problems after that.

As on TV:

Trick N0. 1..."looketh over there.", "ha Ha, madest thou look!" End of trick.

 

[Pat84]

Warning Sighns do not have to identify the agency. They will Say "US Government Property Keep Out" And if they are US Navy property, They will have milepost numbers on the revese side of all warning signs. Everyone in security will have the same refernce numbers.
One Navy site did that, so I told them all to do it

Take a frequency counter and rf meter(very broadband) check out readings you get. Out at Kennedy Space Center there were a couple of areas that used very high frequency with high output power and it could fry you in 30 seconds easily! If the sing isn't bogus(there should be the agency on the sign like DARPA or something) Then you could check out what's going on. See if thee is a no-fly zone around that area, if they are doing high energy research there will be a no-fly zone around it. Check with the local county or state as why you cant get in as you could before. You might have to push them to get a no BS answer!

It could be microwave transmissions. If they are ground level, they will be marked, up on a rooftop, not so much.

There are a lot of things transmitted by microwave these days, depending on the strength, you do not want to stand in front of them. Not only that, it disrupts their signal strength as it cooks your liver, kidney and heart for edible consumption...:

I would have to disagree with " High Frequency = High Energy"

The amount of energy in any frequency is a function of Electrical Power in and the "voltage standing wave ratio" or VSWR of the emitting device
(Antenna).

Many wireless devices operate at high frequencies at low power, including cell phones and routers.

and on a side note.. 60 years ago "High Frequency" was 3-30MHZ
Then along came VHF then UHF and EHF very high/ultra high/extremely high.

Radiation from communications and radar equipment can seriously hurt or kill you. Very quickly.

When we work aloft in the Navy, we have to run an aloft chit and ensure specific dangerous comms and radar equipment is powered down before we can go aloft to prevent being radiated on. Like wise you can not go up to very large antenna's on Antenna Farms without powering them off first.

It cooks you like a microwave does, and can cause cell damage which can lead to cancer, even if it does not kill you.

 

[Edward4576]

There are men working aloft, do not rotate, radiate or energize any equipment to the mast

 

[Mountain]

We had an incident on the battleship Wisconsin in port Norfolk VA, the guy had a chit and went aloft and one of the other ships for whatever crazy reason lit up there radar momentarily. It did not seriously harm him, but it very easily could have. I happened to be in my truck at the time and my radio came to life without being turned on and my speakers went nuts.

There are many things that can put out dangerous high freq electromagnetic radiation, from radio towers, microwave communications towers to the very dangerous.... radar installations.

I was an FCT in the Navy and worked with radar commonly.

Oh yeah! One of my buds was on a Hawk missile battery in the 60's and they cooked their hotdogs in front of the radar antennae. They used a wood stick to place the hotdog into the radar path. Only took seconds...

I would have to disagree with " High Frequency = High Energy"

Then you are ignorant of the fundamentals of electromagnetic radiation. The higher the frequency, the more energetic the photon.

By many definitions, The photon "IS" a definition of the electromagnetic waves energy.

 

[Robot]

Many wireless devices operate at high frequencies at low power, including cell phones and routers.

You are confusing power into the device and energy out of the antenna. There is not a direct correlation.

Again, Frequency = Energy.

"Power" is different. You are confusing the two.

Call "Power" Watts if you like.

Put a given frequency on an antenna, each wave emits a photon. Each photon has an "energy" that directly correlates to that frequency.

Your antenna spews photons of a given frequency,(energy).

Take that same antenna and put more watts into it, while keeping the same frequecncy transmitting. You have simply increased the amount of electrons(charge) moving up and down that antenna.

You may have more electrons moving, but with the same frequency, those additional photons emitted have the same energy, not more.

So when you pump more energy(watts) into a transmitter antenna, as long as you keep the frequency the same, any given electromagnetic wave and it's photon has the same "energy".

By increasing power, you simply increase the amount of photons emitted.

With the same barrel, etc, If I have a .306 machine gun, none of those bullets will go any farther than my .306 bolt action. They both have the "same" energy. The machine gun simply has "more" carriers of "energy"

We could call trees, etc, "attenuation", permittivity and permeability to be more specific.

If we shoot more bullets, more are likely to get past the "attenuation", even though no bullet is more any more powerful than any other.

Send more or less bullets, regardless, the "energy" per bullet or electromagnetic wave is the same.

The OP posted about a fenced in area with a sign that say's "No Access, High Frequency Energy Area" and my Interpretation is that there is a source of "high energy" AT a "high frequency"

The sign isn't warning people "don't touch" they are saying that there is an area of high frequency electromagnetic radiation.

In this context frequency doesn't mean "high energy". The amount of electromagnetic radiation being emitted is a function of the power of the transmitting source and it's electrical match to it's antenna.

High Frequency can be emitted at power levels in micro-watts, milliwatts,watts, kilowatts, megawatts and so on.

If I approach a "High Frequency Energy Area" I wouldn't be to worried if that source was a few watts or less but I would avoid the area if the transmitter was high power.

I don't see this forum being the place to discuss photons.
