Many long years ago, when I was just a pup, I purchased a Shakespeare 'Big Stick' CB antenna. You've seen them – they look like an eighteen foot long, white fiberglass fishing rod. Because of its long, skinny design, the antenna would fit anywhere, on the chimney, up a mast, or shoved among the branches of a tree. Eventually, I got tired of looking at it up my tree, so I took it down and stowed it in the garage, for over twenty years.
Step 1: First step - just try it out
I had always heard that a Big Stick was wide banded, so I tried it on the10 meter Ham band – just a gnat's whisker from the 11 meter Citizens' Band. Not that wide banded, it turned out.
Nevertheless, with the help of a small antenna matcher I had, I was able to get my rig to work with the antenna. I didn't like the setup, though; I was using a single band, 25 watt amateur band mobile rig and wanted to run the coax straight to the antenna without a lot of hoopla. So I thought and thought and tried something else.
Step 2: Idea
Without going into a lot of technical talk, I knew that either an open or shorted section of coax cable could be used to match an antenna to a transmitter. That seemed a good way to do it. That way, the rig would be connected to the antenna with nothing to tune between the two.
