In WiFi is there any standard convention for the polarity of a helical

should build it right or left handed.

Yes I know this will only matter when trying to connect with other
systems that use circular polarity.

Please post how it works out. Also, have you considered building a 4
10 turn helix (heli?) and run in parallel. That gets around the
matching issue.

Yes, I thought about that but I have plans for the 40 turn unit
including the matching device. Also I have access to a Network
Analyzer and S pararamter test set for tuning it up. I think building
the matching network may be easier than build a phasing harness for 4
Helix antennas. However I have never done this before so plans may
change. Who knows, if things work out OK I may build a 4 X 40 turn
device.
