[TenTec] 4229 Tuner Balun Replacement?

[Stuart Rohre]

Well, I mean by heavy construction the size of the core, of course, and 
the number of turns would influence the size of the balun.  A core 
picked to satisfy the band coverage and the power and wire size would 
typically be larger than some common internal baluns.

Twin lead is a great antenna transmission line.  Heavy duty types and 
ladder line are cheaper than good coax and have lower loss.  One can 
easily adpat any station to running balanced line even thru windows with 
good results at little effort.  Putting a piece of pipe insulating foam 
across the bottom of a sill works even with metal windowns.  Another 
piece of foam stuffed between the sash and upper casement seals against 
air leaks.
