The Adventure Tuner Kit from SOTABEAMS is an affordable small project suitable for beginners and pros who will end up with a useful wire antenna tuner. According to SB:
It’s an L network tuner – but with a difference: the L network is bi-directional to increase the matching flexibility of the tuner. Both sides of the L network can be used for the antenna or the radio. It’s got co-ax socket on both sides of the network too so it can be used to extend the useful tuning range of narrow-band co-ax fed antennas – such as making an 80 m dipole usable across the whole band.
The inductance is provided with switched inductors giving a range of 0 – 5.6 uH in 0.1 uH steps. Hyper-bright LEDs indicate antenna current to aid tuning. They are in circuit all the time to give you reassurance that your system is working at peak efficiency. The typical matching range of the Adventure Tuner is 3.5 – 30 MHz.
It looks like another swell Saturday morning project melting solder followed by radio adventures from the field and shack.
