I really don't want to get into a big discussion about this and I understand 
all about the inaccuracies of S meters.  I should have qualified this part as I 
have done receiving tests using the rig S meter and notice a large difference 
between the single vertical and the array.  Gain numbers were derived using on 
the air transmitting to EU stations and interpretting their received results.  
Many inaccuracies I agree but they also notice a large difference between the 
two.  So I conclude that maybe the Comtek box/system is not optimized, and that 
is beyond my capabilities, but it is doing something and I like it.  Phil KB9CRY
