So I gather. :)

The idea is to throw away some of the transmitted and/or received RF
power by using (for example) a resistor network connected between the
radio device and its antenna. Another way would be to put the radio
device and its antenna into a metal box. You could make a few holes
in the box to let some of the radio energy leak in and out - I don't
think the results would be very predictable but I'd be interested to
hear your experience. :)

See for example
and try Googling, there is a lot of information out there on this kind
Be aware that what works at 10MHz or 100Mz might not work at 2.4GHz.
You will need to do some reading on the subjects before you can make
really useful RF measurements. :)
