The trouble with as many as 8 single-throw, high-current, high-voltage
switches in a tuner, is the stray inter-component wiring and inductance and
capacitance they introduce.

Even with a minimum number of, or no switches, it requires TWO independent
tuners, in separate boxes with separate coaxial connectors, to cover the
range 1.8 to 30 Mhz with reasonable power efficiency.

You need practical experience by building one or two to see how they
perform. Try again and then come back!

Don't understand why one should make switches, they are offered in
large quantities at rallies and many other occasions
