Very good descriptive replies here.? Thank you.
Here's some How To:
Hayward and Larkin, "Simple RF Power Measurement, QST June 2001 describes a resistive 40db tap.
On my website you will find a simple resistive tap at part B.I.a. in the Dongles notes.
The ARRL 2020 Handbook section 25.0.10 (earlier editions also have this section) describes inductive couplers.? You'll see an inductive 40db tap in the Dongles section part B.I.b. of my notes.
I have shown some N2PK VNA measurements on these taps.? My Icom 718 power setting numbers do not match power out so in PWR Experiment: Measure Transmitter Output Power I show how to use the taps to tabulate transmitter power output for various settings.
Incidentally, the notes show how to make a plastic RF tight shielded box from an AC switchbox.
Hope this helps someone.
