It is a sidetrack, just noise.


The main point of the discussion has been: An SWR meter
calibrated for Z0=50 ohms will not accurately report the
actual SWR on a line that is not Z0=50 ohms.

Of the four following configurations, in a lossless situation,
which one accurately reports the SWR on both sides of the SWR
meter?

1. XMTR---50 ohm coax---SWR meter---50 ohm coax---load

2. XMTR---50 ohm coax---SWR meter---75 ohm coax---load

3. XMTR---75 ohm coax---SWR meter---50 ohm coax---load

4. XMTR---75 ohm coax---SWR meter---75 ohm coax---load
