I think that an honest question regarding measuring SWR or return loss has gone off on a strange tangent. The answer to the question is relatively easy to answer if we know what frequency range is involved, and perhaps the type of connectors will be used and what the person currently has on hand.

What we don't know is what sort of equipment is available to the person who asked the question.

The S11 measurement is a very common one and is not "black magic" to perform. Usually the results are expressed as return loss (in decibels) or as voltage standing wave ratios.

Since there are several ways to make the measurement, what is needed to describe the procedure to the person asking for help, is to know what he currently has available to make the measurement. I assume that he doesn't want to spend a lot of money buying additional equipment.?

He asked for assistance, and that is what I offered. Possibly free advice is worth what you pay for it.
