Topband: Repost: 160m balun

[Bob Tellefsen]

Bill Tippett says this message went astray somehow,
so here it is again.

For the air-wound balun on my 160m vertical,
I used a plastic laundry detergent tub.  It
is slightly tapered, so each turn is slightly
different from the next, but nothing significant.
I wound mine with RG58 and spaced the turns one
conductor diameter apart.  That's about 1/4 inch
spacing.  I think I must have around 12 turns or
so on the tub.  I hold each turn in place with black
plastic tie wraps.  It works very well, so far as I
can tell.  Totally cheap too :-)  It should work ok
with larger size coax as well, since the bending
radius is fairly large.
