Plastic screws?
REPLACE them with Brass screws with lockwashers!

> I have a 135 foot dipole at about 50 - 55 feet that is fed with windowline.
>  The window line is connected to a 4:1 balun which in turn is connected to
> the tuner in the shack*.  The antenna works absolutely FANTASTIC -- I see a
> 20% gain on transmit and receive over my old coax fed antenna.  The only
> problem that i have is the window line keeps escaping from the screw
> terminals on the top of the balun.  Its an LDG 4:1 balun and has the screw
> down type of terminals with a hole through the center post that the wire is
> placed in and then the plastic screw is tightened down to hold it.  I tried
> stapling the window line to the side of the house so it couldnt escape but
> the shack was instantly flooded with RF, causing all kinds of radio and
> computer wildness when i keyed up.  using a piece of rope between the window
> awning and a stake in the ground with the the windowline caught part way
> between has HELPED but not alleviated the problem -- If anyone has any ideas
> or suggestions for keeping the wire in the terminals it would be MOST
> appreciated.
> Any other comments / suggestions for my antenna system are also appreciated
