[Elecraft] Preamp and Heil mic

[CMKaco at aol.com]

Sorry I was not specific.  I thought that all Heil mics with X element  would 
be the same.  I am considering the Classic, which comes with a pro  element 
and your choice of the HC-4, HC-5 and the IC element for ICOM.  I  am not too 
interested in the HC-4, as I understand that is for contesting, which  I am not 
into right now.  I am more interested in the HC-5, and would like  people's 
opinion on how it compares to the IC element (when the HC-5 is used  with a 
preamp.).  I guess I would be more inclined to go with the HC-5 and  build the 
preamp, because then I could use the pro too.  If I get the  IC element, I can't 
use the Pro element with out the preamp (well I guess if  just build the 
element either way.)
 
Has anybody built the preamp?  Can you fit it inside the mic itself,  or in 
the K2, or do you have to put it in a separate enclosure.
 
Thanks for you kind answers to a newbie.
