All antenna connections for boomboxes are the universal SMB plug so if the antenna connector does not fit into the antenna port on your boombox then you may have one of the following boomboxes which requires a special connector to adapt the newer style antennas.
- XMBB1 boombox
- SUBX1 boombox
- SP-B1 boombox
These boomboxes have a plastic ring around the antenna port which blocks the connector from sliding all the way down into the port. We created a specific bundle that includes a connector that extends the connector to allow it to fit down into the antenna port.
