Absolutely. Make sure you use good quality connectors, cables, etc. If possible, plug the wattmeter directly into the RF output on the back of the rig (NOT the tuner or amplifier), using a double male if possible, and plug the PROPER, good quality dummy load directly into the wattmeter. Remember, every connector you go through, loses you fraction of a db. How many connections, cables, etc., does it take to equal one db of loss? Not too many. One db is 26%! If you lose 1db getting between the output port and the load, the load will only see 74W with 100W output from the transmitter. Something to think about. A typical old style tuner will lose you around 5 watts or more.
