At the two points where you need to open the elements, insert pull-chain

My approach, in the early 50's, was not elegant but
it worked and it was fast. I had insulators at the
mid-point of each leg of the 80m dipole with a jumper
wire across them for 80m operation. The dipole was
on pulleys. It only took about three minutes to let
the dipole down, either attach or unattach one end
of the jumper wires, and pull the dipole back up.
Making 50 cents an hour working at Carter's Grocery
on Saturday limited my resources. :-)
