Using the tabulation, fasten a metered variable dc supply into the wattmeter according to the following diagram. Now JI must be pointed out again that this power meter is intended for use either with 50 i coaxial line systems with low VSWR or with 50fi dummy loads. A coaxial line that is not flat (unity VSWR) or a dummy antenna that does not look like 50fi, which is the case with most HF loads used at VHF or UHF, may cause distorted power readings. If you have doubt about your transmitter power...
