[ADXA] stack match blues

Jussi, drop a phone message or email to the old array solutions contact info. Jay said he would be around for a while, I spoke to him about 6 mo ago concerning above ground 4 sq radials.

Jussi,
  I have a Stack Match II model as well.  My experience has been that the SWR is best when both antennas are engaged.  I have never heard of the problem you are experiencing.

It’s been 25 years since I last used mine, but I never had any problem like that. Both or separate seemed the same except it went up very slightly when the antennas were in two different directions.

It is their two antenna one. The third tribander is still on the wish list. Hamation.com is the guy nowadays producing & selling them.

More than I care to admit.

I don't recognize "SM-2" in particular. Is this the three antenna StackMatch
or two antennas?

Hi,

Does anyone have experience with array solutions (now hamation) stack
matches (SM-2 in particular)? I am running into strange problem on 20m where
the individual antenna SWRs are around 1.5 but when the stack match kicks in
the SWR jumps to 2.1. That is still kind of tolerable but I would definitely
like to find out why this is happening. It behaves normally on 15m and 10m.
