Why are you comparing a 4 element mono band antenna to a 3 element Mosley 
tribander and then wondering why the Moseley comes up short? ??While I'm at it 
here is the 52 ohm RG-8 you earlier said during your earlier vomiting, errm I 
mean rant, ?has not been made since the 
70s.?http://www.belden.com/techdatas/english/8237.pdf

##  simple.  4 el mono is 6.0 dbd per eznec.  (204-BA).   Using a stepped 
attenuator on RX, that is switched in 1db increments,  turns out that the 
mosley 33jr with no attenuation on RX provides the same signal strength 
as the 204-BA with 10 db padding dialed in.    6-10 =  negative 4 db.  My 
conclusion is the 33jrs not only doesn’t have any gain at all, its actually 
–4db. 

##  that RG-8 on ur url is strange stuff...has a 13 ga center conductor.   Most 
213 u has  a 12 ga center conductor.  Foam coax has a 10 ga conductor.  My 393 
teflon coax has  a 13 ga conductor.
