In general, higher frequency signals do not travel as far. The higher the frequency the less it travels. That's why these frequencies have not been used for phones in the past. It would also depend on the power used though. That's a question that could probably only be answered definitively by the Military themselves and they'll never tell you.
I just discovered that the Wavecontrol SMP2 has a field probe available that will allow it to detect up 60 Ghz. The SMP2 with a 40 Ghz field probe is $3,000, but I don't know how much the 60 Ghz field probe is.
Here is a list of what is available in mid-2019:
Wavecontrol SMP2 + WPF40 field probe - 40Ghz $3000~

Wawemon RF40 - 40Ghz $1400~
Nardalert S3 - 50Ghz $1700~
EME Guard - 40Ghz $1800~
Has anyone heard of a frequency higher than 39 Ghz being designated for standard 5G use anywhere? Every city is different for how the frequencies are being divided up among carriers.
...and as far as I can tell so far those higher frequencies won't be used in standard 5G signals from antennas. They will only be used for close proximity large file device to device transfers, and even that is something they talk about as possible plan for the future. It's alot like using a wireless charger which has the device and the charger actually touching. The signal will only travel a millimeter and it won't travel through nearby people. It will only give off the normal EMF radiation that every electronic device emits. I'm not trying to defend the use of 5G but if this is true, it sounds at least like some good news to me. The higher frequencies are the most dangerous. If you're talking about using it for detecting millimeter wave weapons that's another story. A 60 Ghz meter may not be enough. The Active Denial Crowd Control System use 95 Ghz. Of course you don't need a meter for that. You skin is all the meter you'd need.
I googled NBM-520 and I'm finding used ones and similar models in the $4,600 to 5,500 range. By comparison 40-50 Ghz models start at around $1,400. If you want to meter 60 Ghz you're gonna have to fork out the big bucks.

No one was saying telecom companies are using 60 ghz for standard 5G signals. Someone was asking about some military weapons testing or something. We've already established that 39 ghz is the highest we know of. That's what Verizon in Minneapolis is using. Every company is different and it varies from one market to another. Most companies are using frequencies lower than 6 ghz. However, I have read that they will use higher frequencies for direct device to device uploads. This really isn't a risk because the signal does not travel farther than a few millimeters. You are thinking backwards about the risks associated with different frequencies though. Lower frequencies are not more dangerous because they pass through things. That makes them less dangerous. If a signal passes though your body, as all non-ionising radiation supposedly does, then it does not have an opportunity to affect your cells. It passes right through. It is the higher frequencies that do not pass through our bodies that are more dangerous. They will interact with your cells and cause damage. 700 mhz signals are about as safe as it gets. A frequency that low could never damage any cells in our bodies. Millimeter waves on the other hand, don't pass through much of anything. Maybe it can't pass through a wall and get to a person inside, but it also can't pass through your body, so when you are exposed it will damage cells. The eyes, skin, and male gonads are the most susceptible.
