Special Test Considerations
The antenna should be resonant at the frequency of inter-
est. Also, to accurately calculate field strength, the antenna
factor or gain of the antenna must be known, and losses in
the cable connecting the antenna to the Test Set should be
factored in (depending on cable length and/or operating
frequency).
