The autotuner in my FT-920 will tune this antenna flat on most bands.
I do need to use an external tuner on 30 and 10 meters, but this is
easily acomplished by a 2 position coax switch.

Just wondered why you needed the coax switch. If you put the external tuner
between the FT920 and the antenna couldn't you just bypass the FT920 tuner and
switch in the external tuner for 30 and 10 and visa versa for the other bands?

I do this with 2 external tuners. I have an antenna with a similar situation to
yours. My TS870 will autotune ok on 40 thru 10 but not on 80 or 160. I just
daisy chained two external tuners (one pretuned to 160 and the other to 80)
between the TS870 and the balun feeding the open wire feedline. I simply switch
in the needed tuner and bypass the other two. Why *2* external tuners? It makes
for quick band hopping. You switch bands, hear em, push a few switches,
and work em...
