My LF antenna has a big 12" diameter coil that is 5 feet long.

It sits outside on the ground and is accessible for tuning, etc.

I have added a few security cameras around the area to provide extra protection.

I have a small plastic fence surrounding it too.

There is a lot of HV on this coil and you can get serious RF burns.

The RF exposure is not a problem but the RF burns are.

These HD Color cameras are now on eBay for $14.00, Really cheap, <https://www.ebay.com/itm/1200TVL-HD-CCTV-Surveillance-Security-Camera-Waterproof-Outdoor-IR-Night-Vision/361249843789?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649>.


You can run the video into a Video to VGA converter ($10)  <https://www.ebay.com/itm/VCD-DVD-Webcam-BNC-S-Video-to-VGA-PC-Computer-Monitor-Converter-Adapter-Box/222440301898?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649> to a digital computer display

or get a complete multi channel video controller/recorder for $130.
