Testing the Antop UFO, HD Smart Flat Panel, and AT-740 Filter for Digital TV

I checked out some more TV antenna products from Antop USA. This time I have the AT-300SBS HD Antenna, the AT-415B 720° UFO, and the AT-740 5G LTE Filter. I did a little more investigation this time, checking out the signals on an RTL-SDR and opening up the AT-415 to see what's in there!

All three units seem to do what they claim. The UFO antenna is optimized for a wide area (vs distance), so would be good for a moving vehicle like an RV or boat. The flat panel pulls in a few more channels and is optimized for indoor use, it also does a good job picking up FM radio signals. The LTE/5G filter does a good job of filtering out signals outside of the digital TV range.

As with all my reviews, I try to be fair and honest and point out the bad as well as the good. I couldn't actually find much to complain about with these units!
