Normally, the output of the amplifier would go to a tuner, like the KAT500, or whatever flavor your prefer, and then to an antenna switch to select antennas. Some people only have a couple of antennas and the 3 output connections on the tuner would suffice, but most serious hams have more than that, plus a dummy load, multiple radios, etc. You also need to consider lightning protection, depending on where in the country you live. Personally, I have the radio going to the amplifier, which goes to the tuner. >From the tuner, I select either the dummy load or my active antenna, leaving >one output port on the tuner unused. I have the dummy load on the default (power off) port, so that the load is on the radio/amp if the power fails. From the active antenna port on the tuner, I go to a 5 port arc suppressed antenna switch, selecting one of 4 antennas (I need more ports). I left out the multi-radio switching and other complications in this description.
