Typically wattmeters are connected to the output of the amplifier, to monitor the overall station output (whether the amplifier is in use or in bypass) and the SWR of the antenna system.
If you were designing your own amplifier or suspected it of presenting a poor SWR to the transceiver, you might find it useful to put a wattmeter/SWR bridge between transceiver and amplifier to verify that the amplifier is presenting a good match to the transceiver. The second lower-power W2 module might be useful in a two-radio station where one station does not use an amplifier. Or if someone had an amplifier that covered 160-10 and used just transceiver output on another ANT connector for 6 meters.

Do I really need to monitor the K3's output? Or, should I put the W2 at the output of the KPA500. Advice please.
