Funny.... went to website you linked and, read "Frequently returned item Check the product details and customer reviews to learn more about this item." LOL
I have one of those devices as part of my EMF assessment for my station - it’s part of the UK licence conditions now, although you only have to calculate the safe distance from your antennas rather than measure an actual value. I believe the ICNIRP guidelines for non-ionising radiation give a max of around 40 v/m although calculating it the old fashioned way gives a max of around 28 v/m. My unit beeps at 40 v/m and the display turns red as a warning. These figures are for members of the public so as long as people walking by your property aren’t within those fields (in this country at least) you would be fine. However, I’m not to keen on boiling my eyeballs so I like to keep the levels as low as I can 😳
Try running 500 watts to a 25db gain antenna array on 1.296ghz! 71 feet is minimum safe distance! BUT that antenna is 32 feet up and has a 7 degree beamwidth so it doesn't reach the ground for a long ways! 260 feet out so it is a safe distance. EME dish is same gain on that freq but it is never pointed at the horizon...
Aloha Bob, I wonder if you had a chance to use this device while outside to see the Northern Lights when gamma rays and geomagnetic storms are hitting the earth like it did 2-3 weeks ago? I will say that this EMF Meter might be real helpful to track down RF interference from local power lines that interferes with your HF operations on your radios. Even you mentioned the noise level at your old home in northern California in this video. I have fellow Ham that lives near Pearl Harbor/Hickham, where his noise level is around S7-9 on a regular basis. I would like to test this EMF Meter at his house and see if it’s possible to find a source of the S levels he has been experiencing for the last few years and even you brought up the effects of what high RF can do to people like the homeless that have been known to sleep under such towers and develop these bumps around their face and neck areas. Great video and great topic, Bob. 🤙🏻 Todd WH6DWF 🇺🇸
You could see if you can mitigate any of your stray RF by putting in chokes, etc., and take another reading. That would be a cool test. I once locked up a guy for climbing the station's repeater tower. He wanted to get closer to God. I had him checked out at the hospital and then off to the Graybar. The judge was amused.
Although I like test equipment, I don't know how to interpret the results of that EMF meter. That meter is pretty cool, but I will probably stick with the old fashioned way with a radio and/or a field strength meter. Great review!

I saw that. But it also gets 4.3 out of 5 with 160 reviews.

Thank you for the review. Will you be testing Gieger counters?

I would test it against my other EMF meters, but they didn't send me one.
You should go ghost hunting with that thing!
Would be nice for finding stray RF

TinySA is what I use...
To me the RF is kind of useless with out knowing where in the spectrum the RF is. I could be wrong as I’m far from being an expert on this topic.
I would say “no s_ _t!!”
Can this be used as a field strength meter?
Can you speak to ghosts with that?
