Tuners in T for antenne filaire
This is a high-pass T-filter consisting of a variable inductance inductor and two CVs. Each of these 2x125pF CVs has a capacity of 250 pF
Tunner per Antenna tipo canna da pesca

What tuners do
The primary function of a tuner is to present the radio with its specified load impedance
QRP Z-Match
The two variable capacitors are very compact. A simple SRW bridge allows to indicate the best tuning positions and an additional 150 pF capacity can be switched on, to help tuning shorter wires if necessary
