[RFI] FW: Common mode choke on 4 Square feedlines without skewing phasing?

[Paul Christensen]

>Can you think of any negative aspects of doing it this way over making up
some RG400 chokes?

Don't rule out surplus RG-303.  It's not too common but it can be found with
some searching.  RG-303 is similar in construction and power handling to
RG-142/RG-400 but with a slightly smaller diameter that makes winding
easier.  Surplus cost is about USD $1.35 ft.  It works well for chokes where
ends are flared out and soldered but I don't recall if there's a common
soldered or crimped connector that works with its smaller jacket diameter.
As a point of reference, Alpha used RG-303 in some of its amplifiers.   

I've been using RG-400 for inside shack cabling long before it became
popular -- back in the good 'ole days when it was easily had for $1.00 ft.
