[TowerTalk] VNA

[Richard Thorne]

I agree with Tim,

Stay away from the MFJ unit's.

I put up some new antennas over the summer.  We used an MFJ-259 and the 
readings didn't seem right.  We then tried a Rigexpert AA-54 and the 
readings were correct.

As it turns out I have a broadcast station a few miles up the road.
