No. Just coax, balun, wire, balun, coax, balun, wire.

Just FWIW...the pattern of a full-size 80M doublet is probably "cloverleafed" enough by 20M that a separate antenna for the higher bands in a different direction is unnecessary. Been a while since I've seen the NEC plots, but W4RNL did a good write-up on it, including takeoff angles and all that good shit.
But hey, my antenna modeling procedure consists of throwing the longest hunk of wire I can find and throwing it into them yonder trees, and seeing if the autotuner will like it.
Or its closely-related cousin, the Umum.
As in "Umum, that sammich is fiiiiiiiiiine".
