Hey Bro -
I've read all the posts in this thread, and there's a wealth of info here. . . from many well-informed members. There are so many good antennas available today at reasonable prices. The choice is up to you.
Personally, I like BJR's homemade verticals. Especially the one with the 1/2" tubing driven element. As another poster suggested go with 1/2"hard copper tube. Because of "skin-effect," RF runs on the surface of the driven element and the 1/2" copper tube has a very large surface area and will radiate the most power. Just follow all of BJR's recommended install instructions and you'll have an antenna that will kick ass and at a great price point.
Two other points: If the sometimes high winds in TX should damage the antenna, repairing it is just a trip to the hardware store; and the feeling of satisfaction you'll get when you make some DX hookups on an antenna you built yourself is hard to beat.
