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.

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,
I found a Sony AN-1 amplifed antenna on e-Bay. It's a telescoping
59 inch whip with a built-in preamp. It covers from 150 kHz to 30
mHz. Works pretty well.

RDJ,

Here are two ways to Improve Reception with your Sony AN-1 Active
Antenna:


INDOORS: If you are looking to use the Sony AN-1 Active Antenna in
the Attic. Try setting it up with a Double Loop element (Head)
Antenna made of Wire -vice- the standard telescoping Whip Antenna
element.:
* Two Loop Elements positioned at 0/180-Degrees and 90/270-Degrees.
* Each Diamond Shaped Loop with all four sides set at 30 Inches.
* Horizontal Cross-Arms are also set at 30 Inches.
* Vertical Center set at 67 Inches.
* Works better than the stock Whip and has more consistant signal
levels with lower noise.

OUTSIDE: To improve the OutSide performance of the Sony AN-1 Active
Antenna. Try using a 104 Inch CB Whip Antenna element -vice- the
standard telescoping Whip Antenna element.
* The One Piece Stainless Steel CB Whip element will 'weather' better
than the standard telescoping Whip Antenna element over the long term.
* The Added Length and Elevation that you will get by using the CB
Whip element, will result in better signal levels.

NOTE: Both of the above will not result in overloading this active
antenna and the radio.
