I needed wooden jigs to hold the pvc and keep it straight, and make assembly quick.
Yep, jigs are very handy for assembling this antenna. Also, as I noted earlier in this thread, using Plumbers Goop or Locktite Plumbers and Marine Adhesive will give about 45 minutes working time with pvc. The downside with that stuff is that it takes about 24-48 hours for a full set, and a week to get rock hard. So you have to be gentle with the assembly for a few days.
