[Elecraft] KPA500 Combiner

[Jack]

I have to wonder about the rationale of spending anything for that extra 
1/2 S-unit.

Over the years I have worked most weak-signal modes, including some EME, 
so I understand there are instances where an extra db can make or break 
a QSO but I can't imagine that happening often enough on HF to make any 
difference at all.

I'd think it would be far better to invest that $1k+ in aluminum and 
steel that will positively impact both receiving and transmitting.
