Re: impedance test of a TV antenna, How do I adjust 50 ohm to 75 ohm

 

If your just making comparisons between antennas any mismatch would reduce the actual signal strength of both equally so a relative comparison could still be made.

?Good question, I'm sure part of it involves no 50-ohm cables, and probably calibration with a 75-ohm load termination, but there may be some other corrections to VSWR, etc.

Let us know!

Testing a couple of TV antennas for Signal strength and just curious about what they might look at on the NanoVna.
I'll be looking at them through about 70 ft of RG-6 and a SMA to F adapter.
Measuring from 180MHz to 610MHz.
Pretty much a novice here.
