Amplifiers are illegal, though others do use them. The other problem is that amplifiers draw HUGE amounts of amperage from the alternator and motorcycles are notorious for not having a reserve of power in which to draw from. These would include the Classic, Ultra, and all Police models, which although they have a 45 amp alternator, only produce that amount of amps at close to 4000 rpm.Bruce said:Now that you mention the ground issue I remeber reading that somewhere. I wonder if there is an amplifier for the transmitter?
Kit,Kit Carson said:Bruce, I noticed a while back that one dealer was getting the antennas switched upon assembly from the factory crate. Some of the owners manuals actually have photos that have them incorrectly switched. CBs on Ultras can get so little use that one or two owners can go through the bike without noticing the degraded performance. Lift out the tourpak liner and look for a wound loop pre-load coil going to one of the antenna mounts (should be the right side) and to the sheet metal grounding plane at the bottom of the pak. That's the one that to which the CB antenna (has the spring and external coil) should be attached. If not, loosen the tiny allen screws and unscrew the antennas and switch them.
The previous SWR comment also applies.
