Quick skim over building the Pre-Production Signature 9. The 10m element MIGHT change in the future, as an option to achieve very slightly better gain on 10m. Else, this is the cut chart:
If you are reading this line, then the User Guide is still under review – so run with these numbers please:
CUT CHART (that means *CUT* the wire to this length below – don’t ADD on the loops etc to the cut)
Band / Cut (in metres) [intermediate tensions use up this much in cm]
* 40 – 11.55m [there are two tension loops as discussed – they use up 10cm + 10cm]
* 30 – 7.94m [there are two tension loops as discussed – they use up 10cm + 10cm]
* 20 – 5.78m the foldback is 1.05m
* 17 – 3.96m assumes foldback is 6cm
* 15 – (as 40m)
* 12 – 2.83m assumes foldback is 6cm
* 10 – 2.5m assumes foldback is 6cm
To clarify: For instance with 40m, CUT to 11.55m. Same with 20m, just cut your wire to 5.78m. This caters for tension loops and foldbacks.
QRO: 10m foldback. See the User Guide for QRO modification on 10m band, ujsing a closed loop system.
