Gang,

Chas, W1CG has provided some excellent info about baluns and their usage.

He is entirely too modest to mention it, but he has done much practical and
theoretical investigation with balun usage under the conditions being discussed.

He even resorted to the old tried and true calorimetric method of measuring the
loss values he quoted!  His work is documented in an excellent article -the NJQRP 
Homebrewer #8 published in April 2002.  Photos of balun construction and his
test setup can be found at http://www.njqrp.org/qhbextra/8/8d.html

And as Charles stated, the balun details are presented at:

http://www.njqrp.org/balun/index.html

It is an excellent well documented and effective design by Chas that can easily be
duplicated by the average homebrewer.  Yes, you *can* try this yourself at home!
You don't have to be a trained professional.

72/73,

Joe E.,  N2CX
