Studyset 300 Mile Range Antenna TV Digital HD Skywire 4K Antena HDTV 1080p with Amplifier

Bought this for my neighbor, he gets over 50 channels just using this

Works great but I dont think I got all the parts like the amplifier

The unit that I received wasn't item of the picture of the item I thought I purchased

Only got 2 channels, didn’t get the 300 mile range as advertised. Returned and signed up for Sling tv local channel.
