[TowerTalk] Switching 450 ohm twinlead?

[ROBERT WANDERER]

Personally, I've used the pillory method. Two pieces of plywood with indents filed into one of
the long edges. When I close the window, the indents (hopefully) line up. Just before that, I run
the ladder line into the room. Once closed, I put angle brackets at the top of the lower window
to keep it from being opened. Takes but a few minutes to create.

Speaking of 450 ohm open wire, what is the best way to get
the wire into the shack? The flexible strip under the window 
doesn't get it any more.

Hi Bill,

I like the trick of drilling two round holes side by side, running two lengths
of coax with their shields tied together and hooking the lader line to the
center conductors.  It's shielded, balanced line.
