Looks like this will definitely do the job:

I'm afraid of what the quote will be :)

What device could we use to measure return loss at microwave

matters)? A TDR perhaps? Will this cost thousands of dollars or is
there a cheap/simple tool?
A lot of coax testers I see online are targeted at CATV so I'm
guessing they won't test at the higher frequencies that we care about
in our business. I'm afraid I'm too ignorant in this area to make a
good product choice.
My root issue is that I have a piece of equipment which produces radio
head alarms. The manufacturer is telling us it's caused by "reflected
power". They say it could be the unit is faulty, or it could be your
cables or antennas. So I'm supposed to replace cables and antennas
and then wait a few weeks to see if the problem comes back, then
they'll RMA the radio if it does. I'd like to stop wasting time and
just have a definitive way to test the cables.
