Hi Dan,
Back in 2010 while employed at a military defense company I had to take some measurements for the very same purpose. I used a handheld portable unit manufactured by Narda: https://www.narda-sts.com/en/. Don't remember the exact model but it worked fairly well, it was handheld, battery powered, and portable. Had to take some readings of building interior and exterior areas (plus on the roof) that had a ground level log-periodic transmitting antenna pointed skyward about 20 feet from the building (all FCC permitted of course). Used the Maximum Permissible Exposure (MPE) limits in IEEE Std C95.1 as a guide and ended up having to install a small keep out fence around the transmitting antenna (don't remember the keep out zone diameter). By the way IEEE Std C95.1 has MPE limits as a function of frequency and some limits were higher than what I would expect (e.g., much higher than 3 V/m in certain frequency ranges, don't remember details). It was an interesting project. Hope this is helpful.

Would be interested in looking at DC to a few GHz, not for meeting regulatory limits, but rather for grossly high levels that could affect persons who have implants such as pacemakers or artificial joints. So I guess there are regulatory limits that can be used, which would be the immunity levels that these devices are exposed to during their qualification. I know there are test labs that offer this kind of service. Anybody use one and know what type of equipment they brought in with them? Thanks in advance.
