Building a Multi-Band Dipole. Post #1512.

Here's an ultra simple, inexpensive dipole antenna that you can build in a few hours.  Using locally available materials, Bob Plank (KK4DIV) shows us how to design, build, and use a dipole antenna which covers the 40,20, 17, 15, and 10 meter Amateur Radio bands.  Calculators for element lengths can be found online.  Bob used an antenna design program he downloaded from http://hamuniverse.com.  For a bit more flexibility, you may want to substitute 450 ohm ladder line for Bob's coaxial cable feed.  By using ladder line and an antenna transmatch (i.e. "tuner") coupled with a 1:1 or 1:4 current balun, you can get coverage from 80 though 10 meters.
