If you want it simple go get a rubber ducky antenna such as for a Icom A21
or so and stick it on it. When your half buried it the ground you really
don't care if you have a 3 to 1 VSWR or not only that the satalite will
pick it up and the CAP can DF you down! Down get too carried away with
"High Tech" just KISS.
