Question is, can this array of wiring be used as a shortwave antenna?

The problem is that it's a big ground system and it all terminates to earth
ground and all that ground and wire will not make for an effective ant. Sure
you'll receive signals but its a ground system and not an ant. Put up 75-100
feet of wire. If your radio is like mine it will accomadate two ant. I run
one wire north to south and the other east to west and I just pic which one
gives the best reception. You should do a little googling for info on
anttennas. It's worth it to educate your self in more detail on the subject.
