Yesterday I could finally use the analyzer with the 7.25’ feet long of LMR-400.



Hi Bob. What do you mean that the 1/4 wavelength jumper I made ( by the way it’ s LMR-400 ) will invert impedance , while the 1/2 wavelength will not ?

These last days, I was playing with the measurements of the Vector 4000 and could drop it to 1.0 on channel 8.


L2 ( Gamma ) is set to 24 3/4” and L3, which is the top section is set to 28 3/4 “  With the analyzer close to the feed point , at 6 feet high, I had a nice dip on the SWR of 1.0 with an R = 50 and X = 0.



Tomorrow I’ll give you more readings using different coax lengths, etc.
