Hi Angel --

I extended my GPS antenna using RG-58 coax, splicing a piece of RG-58 in 
the middle of the RG-174.  I used crimp-style BNC connectors on each end of 
the RG-58 (one male, one female).  I used the same type of crimp connectors 
on the RG-174, soldering the center pin and building up the jacket on the 
RG-174 with shrink tubing so the crimp BNC would have something to grab on 

Right now there is about 40' of RG-58 and it seems to work just fine.
