Does anyone know of any publication that show how someone has already

out the problems of contructing one?

Try a Lecher wire system described in 50's ARRL Handbooks.

I thought lecher line measurements used a balanced line.
I'm not smart enough to know how to compensate for any irregulariities
associated with open wire measurements of an unbalanced load. And, it seems
that it would be easy enoughto make a 'good enough' slotted line. But,
since I havent found referance to any home built coaxial slotted lines,
maybe its not as easy as I think.
