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...

You don't mention it in your note, but are you in an area of high UHF usage?
Could it be strong signals from other nearby UHF stations who might be
influencing your readings?

The readings of 259's (I don't know about other models or other
manufacturer's analyzers) can be affected in the proximity (a few miles) to
AM (650-1650 kHz) radio stations when doing tests at 160m or even 80m.
Maybe similar effects are experienced with nearby UHF stations (Paging,
com'l comm, etc.).

good luck,
