[TenTec] which balun?

[Richards]

Golly, no.   I thought Rick mentioned that, and posted a ink to a photo 
of one he uses.

On the other hand, I am under the impression a well made balun on a 
sufficiently large and appropriate formula ferrite core works better 
than a coil of cable - even assuming you are careful to make it a proper 
coil, as many hams make them loosey goosey and allow the early loops to 
overlap the later ones (which sorta cancels out the whole effect...) and 
often fail to provide appropriate and even spacing between the loops on 
the coil, etc., (to avoid capacitance between the turns, I think.) 
The one on Rick's web site is a beautiful example, with a good sized air 
space, and perfectly spaced windings.  The Alpha Delta antenna folks 
just say to make a wad of coax, and I hardly think that works as well as 
one carefully and properly spaced.

Just My take.
