Always before antenna.
You can't have too many antennas...

If it's just purely to test the amp's power output, shouldn't you use an adaquate dummy-load rather than having it plugged into an aerial?

I'm no expert as I've never tried this myself though.

The swr meter is installed between the antenna and the amplifier.
Of course you have to make sure that the swr meter can handle the power of the amplifier.

For testing purposes a dummy load would be fine. It makes sure that your SWR is 1:1 and your power output is converted into heat instead of radiation.
