This shows why it isn't that critical.......
All spacings below are inside spacing, not center spacing.
For #17:
1" spacing is 460 ohms with bare wire.
2" spacing is only 540 ohms, which would still be very
acceptable mismatch (only 1.2 : 1 VSWR).
3" spacing is 588 ohms. 1.3 : 1 mismatch.
If you used number 14, a common wire:
1.5" =470 ohm
2" = 500 ohm. 1.1 : 1 SWR
3" = 547 ohm. 1.2 : 1 mismatch
I can use 3" spaced number 14 and only have a a 1.2:1
mismatch.
