Antenna tuner long-fil de 7 a 30 MHz
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. With L - PI - T one-box antenna tuner , we have a very wide matching system for any kind of antenna
Antenna tuner T 3,5 a 30 MHz
This small coupler has a very classic T-pattern and uses an intermediate tap-type choke which allows tuning on all HF bands from 80m to 10m.
Antenna Tuning Unit ATU using the T-Network approch
A roller inductor with 25 or more turns of 1.2 mm diawire (No 17 AWG) on a 50 mm former would be nice for the 100 Watt level and would easily cover 160m through 10m operation
