Shielding of Electrosmog: Some Observations (part 5)
Today I reveal the results of my fiddling with Motorola G23 directionality.
Right then. We came across a well wacko result in part 4 of this series when we discovered that the RF EMR signal from my Motorola G23 Android phone appeared to be partially shielded when the phone was placed face up on some conductive cloth. This wasn’t the case when the phone was placed under the cloth, and I found this most curious. I promised to take another look at directionality and here that report is!
Here’s the equipment I gathered together at 10:20 this morning:
Mrs Dee’s G23 posed for this photo whilst I used my G23 to take the pic; we may think of her phone as a stunt double. My GQ Electronics EMF-390 multi-function meter sits on my well-worn notebook along with a sharpened Staedtler 2B pencil and trusty wooden ruler, but what we need to focus on here are those two strips of conductive cloth. These are slightly larger than the phone to enable me to grab a corner for a fast change, and they are similar in size.
Method
As regards placement of the conductive cloth I decided upon a logical sequence that is best described in a series of captioned photos:
Cloth position 1
Cloth position 2
Cloth position 3
Cloth position 4
Cloth position 5 (under phone)
Cloth position 6 (sandwich)
Cloth position 7 (over phone)
The rather inadequate wooden ruler was abandoned in favour of the shatterproof 12” plastic jobby that Mrs Dee uses to measure her cake tins and whatnot. The idea behind this was to strictly maintain a 22 cm spacing between the leading edge of the EMF-390 and the leading edge of my G23. Moving the itty bitty cloth was darn easy and so I reduced the observation time to 2 minutes per experimental phase, with the final two phases (transmitting/aeroplane) returning to the no cloth setup. Simples! One pot of tea was consumed during the process.
Data collection started promptly at 10:36:00 and ended precisely at 10:57:59, this providing a sample of 1,320 per second records. As before, the EMF-390 internal clock was synchronised with my PC desktop clock prior to experimentation. Even whipping away an itty bitty cloth can take a couple of seconds (and will involve my watery torso leaning over the apparatus) so I labelled the first 10 seconds of each phase as ‘missing data’ to remove the potential for spurious readings during analysis.
