it really depends on the type of operation and measurement you are gonna do but you must "engineer" a way not
to TX regulated traffic anyway . a shield room is your first choice , engineering the patch antenna on the handset would
be another , of course you always can ask your regulatory for temporary limited license to do research and the cost
depends on how crowded your area is .

So how does it work "off-air"? I'll need a shielded cable and attach it
on to the antenna pads of the handset?

The last thing I want is regulatory hassles.
