Dear Eduardo

I have built several helical verticals for 40m and 20m .
I always used Half wave length of wire to wind it fully .
Then tuned it with a GDO for some resonance and tapped a feed point .
They worked well as fixed and moblie antenna .
Happy new year to all have a great time

Best Regards
