This watermelon is useless, it does nothing! I connected it to adjust the antenna and it makes no sound, does nothing, and the needle doesn't give any measurement!

Excellent product, in a very difficult and remote area of Messinia it easily picked up the signal and the installation of the antenna was very easy now...!!

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).
