I had to get trained up, again, on how to use it. YouTube has a great vid on line. My father in law helped me with it and helped me make the adjustments to my CB antenna. It's a great gadget to have and not expensive.

This was purchased to help install a truck radio. It came with the cable to insert it into the antenna line. It seemed to work very well however, I did not a reference to judge it. I am happy with the purchase.

Unit is nicely made and durable. Unit doesn't feel cheap of tinny

Good little meter.

Worked great, easy to use and accurate.

Tuned up a new radio, worked just fine

Works well, easy to use. Have used multiple times as I have had to change things with my install and founds that my antenna does not clear most parking garages.
