Dear Kristinn:
I have used the AEA CIA for several years. It has worked well for me.
It is normally used as a swept frequency instrument so one may see SWR (or
other things) vs. frequency on its screen. I think that the other units
display information for one frequency at a time.

I work with antennas and networks where it is important to be able to
see the whole picture. You may not need that capability. Some people have
found the ability to record an antenna's swr vs. frequency to be valuable.

It gets cold in Michigan and in your country. You may wish to ask if
any of the units you list have problems when it is cold.

Let us all know what you decided.

om...
Hi - I am looking for an impedance analyzer. Primarily for antenna
measurements (only 1,8-30 MHz) and secondarily for misc. lab
measurements (L,C,Q measurements, signal generation, etc.). The
possibilities I have been looking at are (in no particular order,
prices approximate):

a) MFJ-259B ($300)
b) MFJ-269 ($220)
c) AEA VIA ($600)
d) Autek VA1 ($200)
d) Micro908 kit from AmQRP ($210)
e) N2PK Vector Network Analyzer project ($150)

At first glance I have the following points/questions:

- Does MFJ-269 offer anything over 259B in addition to VHF/UHF?
- W8WWV tests (web) don't indicate that AEA VIA performs better than
the MFJs.
- Micro908 is new. Any experiences, comments on impedance accuracy?
- N2PK may be the most accurate(?) but needs a PC and involved
construction.
- Any comments on the Autek?

All suggestions are appreciated, based on experience and technical
quality.
