Review on 📡 Upgraded ANTOP AT-415B: 720° UFO Outdoor HDTV Antenna with Smartpass Amplifier & 4G LTE Filter - Perfect for Outdoor/RV/Attic Use (33ft Coaxial Cable, 4K UHD Ready) by Rafael Lewis

.but it didn't increase OTA reception for me. Before installing this antenna, the channel search will show 41 channels found. I was hoping that a better antenna (rather than two flat antennas with a combiner in the attic I randomly assembled) would provide at least the same number of channels, but with a more stable OTA signal. There is no such happiness. I installed this antenna at the highest point in the attic and put out a scan of 12 channels. I've tried it with and without the amp, turned it all the way on and off, and tried to mount it in the same spot as my antenna. Multiple scans with different connection configurations could not improve the initially found 12 channels. In fact, a subsequent scan found four channels and another scan = six. I reconnected my original antennas and rescanned to find 36 channels. I think I was better off where I was originally. Reluctantly sent this antenna back. I had high hopes for this, but it didn't work for me. You may have better luck with your location and system. I give it one star because it was easy to install. but that's all.
