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.
