Default Re: Antenna recommendation for 40 and 80M bands

Symmetrical dipole (whatever length fits!)

open wire feeders (about 4 inch spaced) to Z-match balanced ATU

Forget unbalanced ATUs with baluns after them, a balun to handle the range of impedances and frequencies is problematical.

The fully balanced nature rejects local QRM
The isolation of the ATU handles issues of PME safety.
