Convenient (non-weatherproof) connectors are available for humble,
TV-style, 300 Ohm twinlead. But I am not aware of any sort of
connectors for 450 Ohm window line.

Does anyone in this NG know of any such connector? If yes, where
can they be purchased? And if not, how about clever work-arounds--
perhaps doing something with banana plugs?

Thanks and 73,

Ed
