[LCC] Antenna Analyzers - what do you use?

[Charles Morrison]

NG5X has one of these as well from Dayton last year.  Says he loves his as well.  Good buy!

I purchased a RigExpert AA-54 earlier this year and love it!  It's handheld and does everything that I need and more.

 

Not only will it scan any range you need within 0-54 mHz (the less expensive AA-30 goes to 30 mHz), it will scan three different frequency segments at the same time if you were to use it to check a tribander.

 

With the software that comes with it, you can store graphs on your computer through the built-in USB port and look back to see what your antenna was like at an earlier time, etc.

 

I did some screenshots of the graphs that are produced by AntScope software that comes with the analyzer when I was converting a KT36 to a KT34.  You can see these graphs here:

LCC members:

 

I’m curious – which antenna analyzer do you prefer for portable use?  And why?

 

My best guess is the MFJ-259 type is the most common, perhaps because of price.

 

I’ve used MFJ types, and suppose they are ok.  I’ve also used the AIM 4170, which is a great piece of gear, but it is not portable.  If all measurements were from the shack, there is no doubt that I would buy one right away.

 

 

I like to know what is happening across a range of frequencies, not just at a single point.  I want to know the sign of j as well as the phase angle.  I need a device that can be used to tune filters/coax stubs.

 

What is your input?
