Terry,

As many others mentioned? Hex beam is the best choise. I have 3 of them
made by EU manufacturers (very good quality). And one of them
(www.foldinganteannas.com) is even foldable and very light weight.

You may also look for MW0JZE Hex. he also makes light version. Do not
mess with Al antennas. Hex Beam is much better and easier for portable
operation.
