Do you have an antenna analyzer?

If so, it should be possible to scale up a Force 12 S5 design to 40m, ie
twice the length, and twice the length on the bars.

Then, the analyzer will tell you the matching values needed for feedpoint.
Or, simply feed with ladder line to shack tuner.  Might have to take off
feeder in between operating sessions for stealthy look.  Clip leads
facilitate that.
