Hi,

I am not sure this is a true, but winding in opposite direction reduces parasitic inductance. But in general winding both wires from bottom or left from bottom and right from top does not matter. Thus, It might be very small increasing in correctness (probably a not noticeable) in case of starting winding both wires from bottom.

I also tried to use rg316 coax with shielding to lower SWR on upper bands (I have 1.2) but got the same results as without shielding. Even factory transceivers use simple unprotected wire or even single core SWR meter.

The only piece of advice from my side to use RG58 internal (central) wire with insulation to keep wires directly in the middle of binocular holes (see attached photo). =)
