Turn your existing 80-meter dipole into a broadband antenna by simply modifying the feed line. Super-strong injection-molded center insulator with built-in SO-239 connector and hang hole. I have used the ham stick on 80 meters mobile with an antenna tuner. readings of less than 2:1 over most of the 80 meter amateur band, and 1:5 to 1 over all of the 40 and 20 meter bands. As I had a so called "line isolator" laying around I put it at the junction of the 75 ohm matching coax and the main. The most simple is a 75 meter dipole fed with open wire or ladder line, tuned up on 160 meters, as shown in Figure 1. There are numerous reasons why people shy away from trying to put up a good antenna for this band:.
