Having read the article in the November QST about the Arduino Antenna Analyzer leads me to the following question ;

What needs to be changed to the hardware to allow the analyzer to work on the 6m & 2m bands?

I see some basic edits to the code that need to be made and I am sure there may need to be more.

I am want to make the "As Designed" project my winter build.  But would like to know more in depth on expanding the operational
parameters.

I look forward to your guidance.

If it is something like the K6BEZ antenna analyzer you will need a dds/frequency generator module that can run at higher frequency.
You will probably also need to design the reflection bridge for higher frequency if you want to go all the way up to 2m. 2m can be done with a SI570 but then the arduino code will have to be changed.
6m is a bit simpler you can use a AD8951 that will go up to about 70MHz but have some harmonics.
Have a look at hamradio 360 page, http://www.kj6vu.com/?p=1014. I have buildt this one and it is working as a charm, but the code is a bit slow. There are several versions of the code font on internet that will run better.
