I'm brand new to radios. This is all foreign to me. First off does anyone have a good place to start, to get a good base knowledge so I know what I'm looking g for. Second I have a old sbe Trinidad II base. It has a pa/cb switch. Im looking for a decwnt antenna to start with. Like to stay as close to or under $100 as possible. What should I be looking for? Th, much appreciated.
