An Untanglable Twinlead 20-Meter Dipole


The March 2010 Trail-Friendly Radio column in WorldRadio Online magazine features a 20-meter folded dipole that is great for backpacking. Click here to visit the WRO Web site. It's free.

The secret for this antenna's success is an easy-to-build L-C matching network, whose schematic is shown above, and pictures below. A center support was fashioned from one-quarter-inch clear plastic and insulated nuts and bolts.

A view of the antenna's configuration inside the garage at KI6SN during testing is shown at the bottom.
