Tricky is right about the 1982 thru 1987 1100 and 1200 Aspencade, Sei. and Limited were sold with a Tri-Way antenna installed and the CB radios came with the splitter. Most people that added the second antenna for looks and then complained that the CB no longer had the same range as was achieved with the single antenna. The splitter had 2 tunable capacitors for the CB and AM/FM and was never set for the SWR without adjustment of the antenna and the splitter. I might add that the Kawasaki Voyager, Yamaha Venture, Suzuki Cavalcade, and Harley Ultra all used the Single Antenna with splitter for the CB but all decided they could make an extra $$$ by offering a second antenna.
