[TenTec] openwire feed OT

[Mike Hyder -N4NT-]

Seems I recall numerous references to baluns becoming "saturated" and thus 
lossy when not used in matched aerial / feedline applications.  If this is 
true then it seems to me that use of a balun with an antenna tuner is not 
the best practice.  I would appreciate someone elucidating this point.

About Paul's question, I use a W5GI "Mystery Antenna" I think.  I've never 
been sure what it was called.  That antenna/feedline couples the twin lead 
from the aerial to a piece of coax some 15 feet long (or thereabouts). 
There is no balun.  The antenna seems to work pretty well.

I would like to reopen the discussion on getting open wire into the shack.
A while back there was quite a discussion on wheather to use a 4-1 or a 1-1
balun when going to coax from open wire outside the shack and then running
coax in to a tuner.

No one mentioned just hooking the coax direct to the open wire without a
balun.

First I realize that you are going from balanced to unbalanced. How would
this differ from feeding a dipole direct with coax and not using a balun at
the feed point?

I would like to put up a temporary loop and it is not feasable to run
openwire in to the shack. But I would like to feed it with open wire from
the loop to where it comes into the house (cheaper than buying more coax).
So I am looking for suggestions.

Since I am all T T it is only partly off topic.

Thanks
