Check out the numbers below. W8JI is correct, solid wire of the same
diameter has lower resistance then stranded wire BUT it's very close to be
negligible to worry about on 160 meters! I have used #12 stranded UV
resistant double coated wire for years with good success.
construction: solid
conductor size 12 AWG
area 3.309 mm^2 (square-mm)
area 6530 CM (circular mil)
diameter 80.8 mil (1)
diameter 2.053 mm (1)
DC-resistance 0.00521 Ohm/m
tensile strength 99.26 kgf (2)
weight 29.415 kg/km (Cu)
weight 8.934 kg/km (Al)
Note:
1. diameter of stranded conductor is an approximation.
2. tensil strength of crimped terminal is about 60 % of conductor.
