Cheap?
Measure? What do you want to measure? How accurately?
.
We have a fieldfox. To get to 60GHz a downconverter was recommended. Comparatively cost effective solution. Relatively to buying 60GHz gear. :).
Then there's an antenna.
.
Keystone instruments also have USB, thermocouple-based power probes. Claim good range on them. Obviously need some calibration before use.
.
Schottky diode?

Well it's to measure the field strength in homes. Just a rough relative measurement as you walk through the house, to test for unsafe levels.

If it is from 5G then it's at safe levels. It's in the design of the standards. :)
Measuring field strengths is not as simple as some imagine. Multiple path makes it complicated. It won't stay the same over time or space. With a wavelength in the order of 5 mm and a reflecting environment, spatial variation over very short distances may be substantial.
Also 60GHz is chosen specifically because it does not go far, attenutates very rapidly with distance in air. It corresponds to an absorption line so the air itself absorbs it quite quickly.

Well there must be some meters available nevertheless. Kinda like the wifi meters.

A 5G phone or other 5G device will likely give you an idea of the signal strength.

Anyone know of cheap meters to measure the new 5g signals?


5G IS NOT 60 GHz

Hello,

It won't be cheap:
https://www.theemcshop.com/rf-field...520-broadband-field-meter-100-khz-60-ghz.html

About the frequencies for 5G NR, here a piece of the wiki:

Frequency bands for 5G NR are being separated into two different frequency ranges.
First there is Frequency Range 1 (FR1)[1] that includes sub-6GHz frequency bands, some of which are bands traditionally used by previous standards, but has been extended to cover potential new spectrum offerings from 410 MHz to 7125 MHz.
The other is Frequency Range 2 (FR2)[2] that includes frequency bands from 24.25 GHz to 52.6 GHz. Bands in this millimeter wave range have shorter range but higher available bandwidth than bands in the FR1.[3]

What are considered "safe" levels, and based on what ? We really don't know what the short-term effects of RF of any frequency are, never mind the long term effects. Life has had millions of years to "evaluate" naturally occurring EMR. We have had less than 100 years to evaluate man-made EMR.

Looks like the Narda meter might suffice. Anyone has asked for a quote?
Just using the meter on a phone though, would not show over-strength levels.

Yes those would be a start, at least for low-signal areas. But for over-strength areas near the antennas, I think a separate dedicated meter is needed.
