My brother is a serious SWL'er with a recent model of Drake SW receiver. He
listens exclusively to 30MHz.

He has asked me (the family electronics geek) what his options are for an
antenna on his balcony. (The management doesn't allow anything on the roof of
the building.) The balcony is a roofed 6 ft x 8 ft affair.

Is it possible to put a loop antenna, coiled inside the balcony roof, each
coil being supported, possibly, by a custom plexiglas support in each corner?


I'm open to other possibilties, but with the limited space, I quickly run out
of ideas.

Take a 2"X2" 8 foot long
Wrap a Dipole around it
and feed it with a TV type 300 Ohm to 75 ohm
Matching Transformer.
You could even wrap a Multiple Dipole.
I build one with 2 Spools of Rad shack
clear speaker Wire. 75 dual strand, that
you unzip apart.
cutting one at 50 and 25 feet, and the Other
75 foot as the Base Winding
I used guike qlue to hold it in place
and made a pedastal for it,
so I could take it Inside when I needed to
It worked great, and took it Camping as Well
I know about the center-fed masts, such as

but I'd like to help him with an inexpensive DIY solution, if possible.

Any suggestions would be greatly appreciated.

Thanks,
