Aerial connections - live chassis

[Yorkie]

In sets that had neither a frame aerial nor ferrite rod, it was commonplace to have either a throw out aerial or an aerial socket, isolated by a capacitor. The Portadyne Princess that I'm working on just now has such an arrangement - a 15ft 'throw out' aerial, isolated by a 0.002uF cap. (See attached circuit). Same will apply to many similar sets - Champion, certain Little Maestro's etc.

Hope that helps Rob.
