It may not be spaced correctly for 450 ohm line but in the early days when everybody used open line feeders :

Then again, you could disassemble the basic bits from this and reassemble on a different insulating material (eg kitchen chopping board) with the spacing set up differently to maintain the 450 ohm spacing.

Yep, good ole knife switch!  A change in spacing for a few cms is unlikely to cause much of problem. You could mount it in a box with a push rod coming out of the bottom to water-proof it and it should be easy to devise a remote way of doing the push-pull from inside the shack.
