    Two similar instruments with very similar measurements using very similar settings, though the more recent set does have the CAL enabled. Same hay stack. Still no deep dip on the RL. Not fond of either, but if you go strictly by the Anritsu, your antenna and line seem good. But, your experience proves otherwise. From the excessive duplex noise during repeater operation, to the loss of range, it's broken in a way that is hard to detect with a static test. I would go ahead with replacement.

    you never want to do DTF limiting your Fstart/Fstop to the band of the antenna, your Fault Resolution is going to be in the 20 to 40 ft, so all problems are going to be masked out.
