It is a simple L coupler that can be of great service for fixed or mobile traffic.

Antenna tuner multi-type matching system
The above antenna tuner is a multi-type matching system in the same box, which includes L - Pi and T networks. For example, If you can't matching a random antenna with PI-type tuner, just turn the S1 switch in other position, ie T-type and try again.
