Here's an interesting antenna project from John Reisenauer, Jr. (KL7JR) that could help those with limited space for a full dipole antenna.  John has provided an excellent diagram, materials list, construction notes, and photographs to help you build your own 5 band vertical antenna.  With a good antenna "tuner", low loss coaxial feed line, and a simple ground radial system, you could be on the air with a decent signal in a few hours.

Most of the materials for this multiband vertical antenna can be found at the nearest building supply outlet or neighborhood hardware store.

Here is a basic diagram of the antenna and the required material to get you started.  Please insert the post title into your browser to see the diagram.

Material List:
1 ea 10 foot 3/4 inch EMT conduit
1 ea 10 foot 1/2 inch EMT conduit
1 ea 102 inch CB whip
3 each hose clamps
Assorted bolts, nuts from junk box
Insulating support for base of antenna (3 inch)
Assorted # 12 wire or plumbers tape for radial ring
4 to 6 or more radials  + - 16 feet long from wire for each radial
