I bought an MFJ-269 from KC7SLO in September last year. When it arrived, I
tested it and found that the UHF portion did not display the correct SWR.

I
tested it with 3 different UHF antennas. It works fine everywhere else.

The
problem was that although on the air tests with the antennas all showed

them
with low SWR in the proper frequency ranges, the analyzer told me on every
one that they all had wavy SWR patterns. For example: 415mhz 1.7, 420mhz
2.5, 423mhz 1.2, 431 2.1, etc... It was obvious that the analyzer was
displaying the wrong SWR on every antenna.


What makes you think the antennas don't exhibit that SWR at those freqs?

Because I did on the air tests with my watt meter and found that the SWR is
only good in the rated portions for each antenna. Besides, if these antenas
were as broadbanded as the analyzer is saying, the manufacturers would be
selling these antennas for more than I paid for 'em.
