I want to build an antenna for my shortwave radio. I live in an apartment.
So it would have to be something I could put near the window. No longer
then 3 feet.

My idea is having 2 wires in a coil. Wrapped around PVC tubing on each end.
It would look like the letter T. ( I am not sure which size of tubing to
use).

I am not sure how many feet of wire.

Which type of wire.

Should the wire be shield or not shield.

If not shield, then when I wrap the wire, can it touch itself in the turn or
must it be spaced apart?

Then comes the end of the two wires. What do I use to solder to then plug
into my portable radio?

And is their a way I could make a tuner and have the wires connected to that
first then to the radio?

Thanks.
