Default Internal aerial connectors

My external AM aerial is distributed into different rooms in my house and is connected to sets in those rooms as may be desired at any point in time. Because I want to disconnect any sets in rooms that are not currently being listened to, from the aerial, I use a system of short links that can quickly be deployed to make the aerial connection to a particular room. The key components are the gold plated, bullet, 'banana' connectors used on the links and stub ends. These ones are nice because they are solderable and come with heat shrink sleeves. It's a simple matter to make or disconnect a particular section of the aerial as it passes from room to room. Thus, only only radio is connected to the aerial at any point in time, and reconnection takes seconds.

Very neat.

Until the 60s, most radio aerials had a knife switch on the windowsill which allowed them to be disconnected during thunderstorms. That would be a nice historically accurate way doing the same thing, though they're a bit bulky by modern standards, and are very rarely seen now.

I had a similar switch to earth my topband long-wire in the '70s
I got sparks jumping the gap in a thunderstorm if it was nearly closed (!)

Never tried the full on Benjamin Franklin thing with a kite
