[Elecraft] How can I determine the ratio of a balun?

[Dr. William J. Schmidt, II]

And if it's 12 ohms...its 1:4 or backwards...

Put a 50 ohm resistor or dummy load on one side and connect the other to an
antenna analyzer or radio with SWR bridge. If the SWR is close to 1:1 then
it is a 1:1 balun. If it is more like 4:1, then it is a 4:1 balun!

balun.  How can I tell which one it is?  The balun is sealed.
