The IMAF is the perfect accessory for people who want to use their CB antenna for their CB and AM/FM radio.
Unlike the receive only antenna needed by the AM/FM radio, a CB needs its antenna to be resonant within the CB band. Tuners that allow the AM/FM antenna to be used for CB bleed off power to keep the CB's output circuits from literally burning out. If you only want one antenna, than the only wise choice is to use a CB antenna and the IMAF.
Installation is easy too! Simply disconnect the antenna coax from the CB and screw it on to the IMAF. Then, screw the PL-259 lead to the CB and put the pin-plug into the AM/FM radio's antenna input socket. Both coaxial leads are 18" (46cm) long.
