Look for someone who services two way radio or marine electronics (often

an antenna on the roof). They may be able to suggest someone.

I found some electronics rental place nearby, will talk to them on
Monday.


I doubt that you really need a spectrum analyzer. If they make rated output
with rated drive, they are most likely to meet harmonic rejection
specifications. Power supply, dummy load, wattmeter, and a signal source
should do it. Also, it would be nice to be able to monitor the supply
current.
