No need to spend $$$$ for this purpose, as direction power is unimportant.
Only forward power goes to the matched dummy load! Therefore, a
easily calibrated RF probe will do perfectly - a diode, bypass capacitor
and series resistor to the dc run back to the shack is all anyone needs
for this purpose. You can use your shack wattmeter to calibrate the
diode probe on the 4 square dummy load before carrying the load out
to the feed point.
