The readings that you describe suggest that you have a larger signal in the lower frequencies.

Note that when you bring this meter close to a surface, the readings will be distorted. Almost any surface will do, including your body. It is an artifact caused by the grounding effect of the surface. Ignore these readings.

There are many meters which can tell the direction of an RF signal (directional). Some meters cannot (Isotropic).

with RF meters it is very important in having good compensated antennas.

As far as I can see from here, I do not see any antenna from your mentioned
Alpha RF meter.

What about your german GREEN meter??
Type??

The man from your environmental company is nuts.
Most meters nowadays use logarithmic periodic antennas, whith which one can
easily pinpoint the RF sources.
Like those from Gigahertz Solutions for instance.

you are colorblind. ;o))

That meter is white, like snowwhite.
High Frequency Meter (Cat. #A481)

That meter does have a logarithmic periodic antenna, and can pinpoint the
sources.
Its readings in uW/m2 are very accurate.

If you wish to measure below 800 MHz, there is the HF Analyser HF 59B, with
the special UBB antenna.

Hi,

I'm new to eSens.

I used this very same meter a while ago. I found power from 10µW/cm2
to a few hundred µW/cm2. I don't think I used the attenuator (a
small piece of metal you add to the antenna wire).

This is in contradiction with the description on the web page : range
from 1 to 1999µW/m2 that is 0.1999µW/cm2.

That meter is NOT accuarate at all! Its just a winkidinki
widebandmeter. So forget the reading.
Buy a spectrumanalyzer like the SPECTRAn from aaronia (about 250 EUROS
only!) and you get a ACCURATE reading which you can afford ;-)
See www.elektrosmog.de/Spektrumanalyser.htm or have a look on the
lessemf website...

I mean the "white" (or "green") meter. About the NARDA: Is it
frequency-selectiv (spectrumanalyser) one ? If NO then forget it.
Also dont forget to make a 24hr RECORDING otherwiese the measurement
is not worth the paper it is written on. A lot of people forget that,
even "professionals". On that you can easily see if they are just
interested in your money or realy know what thea are doing...

Ups! Its
http://www.elektrosmog.de/Spektrumanalysator.htm 
sorry on that. There also is a english DOC at:
http://www.elektrosmog.de/Gutachten/Spectrum_Analyzer_E.doc
I use that HF-2025E meter now for about 3-4 weeks and must say: BEST
BUY, you cant get a better meter even for 10-30 times the price!!!

I was able to use this white one with the green plastic antenna.  
Only meter I could get so far. And the good thing is that it is very
easy to use. Now, as I've already said, it measured up to at least
600µW/cm2. And I was told it is the sum of all the power of the
frequencies in the phone mast range. Of course I would like to
understand what it means really.  

I contemplate buying the aaronia inexpensive set at around 300 euros,
but I'm puzzled by the range limit ridiculously small like max of
10µW/cm2. This is lower than the minimum I measured in my place...

Hello,

let me state it quite clear.
The Spectran meters from Aaronia are only in a BETA State.
They are not finished products.
They should be regarded as winky dinky at the moment.
Whether they are accurate and work as promised seems still far away.
Patience seems to be in order.

If you are not familiar with a normal RF meter, and do not understand what
it means and what you are measuring, than those Spectrans are to be avoided.
They are very complicated to handle.

Be aware that all mentioning in newsgroups about how good the stuff from
Aaronia is, comes from one and only source: Aaronia itsself.
They write under different pseudonyms.

The readings on your meter are not the sum.
You should slowly turn the meter around and note the peaks from different
sources.
Because the readings are in uW/m2 (not cm2), you may add those values in
order to determine the total load.
(If the readings were in V/m, you are not allowed to add them together. The
separate values must be raised to the higher power, added together and from
the sum, the square root must be drawn, in order to determine the total
load)

Thanks Charles for the explanation. It makes things already more
clear. I understand now that the V/m is the electromagnetic field
coordinates.  

Now it is frightening to add the power values along the three
directions, cause it makes it more than the root of sum of the
square...

Also I just used the white and green meter one day, but from what I
recall the values were read in µW/cm2. Not completely sure though.  
Although it looked consistent with what I read on the net for a phone
mast at about 100 meters. The max values I got, on the balcony just
facing the phone mast was something like 600 µW/cm2

The set of two detectors at 300 euros are not the spectrans, it is
the HF detector 2, something like that plus the low frequencies
detector. The spectrans look great, for the price, but yes the
documentation does not look easy to read. Of course I want to buy
something I can rely on.

I meant the sum, in case there was more than one frequency emitted by
the phone mast.

I checked the three orthogonal directions.

Please, I need something like a reference. So I suggest if anybody
could give the "usual" values in µW/cm2 or µW/m2 for a phone mast 100
meter far, horizontally, with no obstacles.

I repeat the number I got was in the range of 600, I assume it was
600µW/cm2. But from what I read here, it might be 600µW/m2 which is
10000 times lower.

Of course once it's shielded in the appartment the values get lower
(don't worry I don't have this value at the sleeping place, at least
not any longer).
