This is a review of this Chinesium, 0.1MHz to 2.4GHz, RF Signal Frequency Counter! The device is a very inexpensive unit that can be purchased on eBay.
Note: I have found a similar unit like the one in this video, that includes the durable clear plastic case. I have included a link to the one I found below. I am no affiliated with the seller in any way. Nor do I receive compensation for providing the info. It is simply included here as a service to my views.
