It is more than 5 years ago that I tried receiving TV from window antenna....
Recently I got curious if the antenna's elements need to be electrically connected?
I mean, metal-to metal contact, by squeezing with bolts or soldered.
After all, the frequency of signal is pretty high...
Therefore, I used thin, insulated wires, bought some time ago from hobby craft store,
10 pcs of Printed Circuit Board with one-sided copper foil, and medical glue tape,
of course, temporarily....
and, the antenna worked! I guess, the capacity between PCB foil and the insulated wires was enough to deliver signal.
For stronger stations, it worked with just 2 whiskers. Reversing the vertical wires on the top and bottom did not make any difference.
Pictures, (some-annotated) - follow

Another Marconi here. :)
Hehe, I wish I had Marconi skills... thanks for compliment...
I was just curious, if metallic contacts between antenna parts were mandatory:
now I know, that capacitive coupling is enough. It does not have any practical value,
since making/building an antenna is better done with metallic contact of parts, through soldering, or welding, or bolting the parts together
cheers, polgyver

Not sure what is going on there, but capacitive coupling is not likely. I suspect direct electrical contact would work much better.
