I hope you didn’t take the whole length of coax and stuff it inside the “L” shaped portion of the antenna. If so, shorten it (as per the directions) and put it back together. If the RG-59, 75 ohm coax is the right length, the feedpoint inpedance is very close to 50 ohms. At least, it has been on the antennas I have constructed. The antenna also should come with a BNC to F connector adaptor. If your kit didn’t have one, call Ramsey and ask them to send you one. Then you can feed the antenna with RG-8X or RG-58.
And finally when you get the antenna constructed the way you like it, paint it with flat black latex paint. It will shed ice in the winter, block the destructive UV radiation to the PVC pipe and look a lot nicer. As far as the bigger pipe is concerned, it would only add considerable weight to the antenna. Hopefully you glued the antenna together, right?
