Quick setup will be a linked dipole trimmed for 20m and with a few m of string on each end; no ATU.
One helper holds pole; peg one guy (only) downwind.
You hold pole, sending one helper with each end of the dipole to form a shallow V upwind and peg down ends of string.
Works fine Force 4 wind and below; needs 3 guys in stronger wind.
I use this setup with a 60/40/20 dipole; erecting single handed takes longer walking to-and-fro to the ends.
