Here's another approach, that you, as an engineer, might appreciate.

Now that looks Intriguing!
I'd like to end up with an SWR no more than 1.5:1 across the band. Typically I can (IIRC) about 15 KHz on 160.

The fan dipole on 75 can  give much wider, usable areas.
With SS amps I'd like to be able to QSY with all the knob twisting.
These may not let me reach that goal but they could be grouped in my normal operating areas.

I haven't had a chance to really look at it, but the idea looks promising.

Thanks Jim

I replaced a lot of Ten Tec antenna tuners with coax and relay switching.
