Hey folks,

Thought I'd share the results of some recent successful indoor
antenna experiments. I wanted something to take on the road and
also use when an outdoor antenna isn't convenient or practical.

Sounds very good. I imagine it would really improve hotel-room
reception over the whip built in to my Eton E1.

Thanks,

It's interesting when you break the loop circuit (switch located halfway between the ends of the loop) how the signal sometimes goes up (though more often it goes down) but the noise nearly always increases.

There's definitely something about the loop configuration that is rejecting electrical noise.

Hello Ross,

It would be interesting to test it against some commercial products such
as the Sony AN-LP1 loop antenna, Tecsun DE31/Kaito KA31, or the
Wellbrooke used by Drifter (certainly not in the same category).

Can you have this opportunity ?

Good SWL,

Charly

I do have a Sony SW7600G so if I came across an(other) AN-LP1 I could pair them up and try the pair against it. Not in my immediate plans as they're a bit hard to find and not that versatile if I recall -- being tied to Sony radios if memory serves.

I recall trying a KA31 or earlier incarnation and being singularly unimpressed. Lost that, an AN-LP1 and a ton of other equipment, in a storage unit robbery years back, and haven't replaced any of it.

The KA31 is cheap enough I think it's well worth buying just for comparison. Thanks for the idea.
