Excellent product. It does what it says very easily. I installed the antenna on the roof without knowing where it should be facing. I tied the antenna where the sound was loud and that's it. Perfect reception for all channels.

For its price, it is simply excellent.
I don't give it 5 stars because of the construction quality.
It looks cheap.

I bought it for terrestrial signal. It does its job. But it's like an ON-OFF. It goes to the extreme end of the scale when it finds a signal or to zero when there is no signal. Don't forget to adjust the sensitivity button to detect the signal. It operates with a battery (not included).
