Unfortunately with the recent change in Thingiverse's policy of model ownership I am moving all of my models to my own file services found at http://www.farvew.com the link can be found toward the bottom of the page.
Okay this the second version of my 5 turn RHCP FPV Helical antenna.
1: Slide the left and right sides together
2: Feed your helical coil up from the bottom until it ends in the recess.
3: Put your reflector into the base and slide it onto the helical frame to check your coax length
4: Solder the coax to the reflector
5: Slide the reflector and base onto the frame again and glue it inplace
5: Solder the inner core to the copper helical and your good to go!
would suggest adding some hot glue to the point of entry for the coax to help stiffen it up.
