2.4GHz helix (newbie)



Hi all,
I'm attempting to build an helix antenna for 2.4 GHz. Actually two helix,
one 22 (or maybe more) turn RHCP and one LHCP for feeding an offset
dish. The question is: can I use 4 mm copper tubing to build these helix
using G3RUH's instructions and methods or do I need to recalculate
the whole thing? 
Thanks in advance
