I was looking at the Telarana on page 55 in volume 1 of the antenna compendium and I was wondering; If a person were to make the central hub so that it were to hinge at the point of the two forward spreaders, the whole thing could be engineered to be collapsable right? If you look at the hub as if it were the symbol for the Japanese yen, then I am talking about the top of the "Y" ie: this part;"\/". If that were able to fold back on itself, and then the fiberglass pole sections broken down, then it could all fit inside a duffle bag and reasembled so that a person could mount it on an extendable pole on the back of his semi-truck right?

So a vertical or a screwdriver is going to outperform a telerana?

A top quality, properly installed motorized (screwdriver) antenna will outperform virtually every other mobile antenna in existance.

You can always cobble up some monstrosity, such as the one you reference, but they simply aren't practical for day to day mobile operation.

I don't think you are getting what I am asking. I don't want the telerana as a MOBILE antenna, I want to make it so that it is portable (maybe that would have been a better choice of words). I want to configure it so that I could assemble it and use it when I am stopped.

OK, I see where you are headed.

Having tried a lot of "portable" antennas over the years, personally, I still don't think it would be worth the effort, compared to a properly installed motorized antenna.
