Pardon me if this is the wrong group to find some answers. I'm using a GE
Superadio III and would like to receive 2 frequencies. AM670 from Chicago
and AM1070 from Indianapolis predominantly night time listening. I work
inside a factory and can't receive either of these unless I get near an
outside window or go outside.

I'm considering buying a tuned loop for these 2 frequencies from
http://www.amradioantennas.com/. He's quoted me a price of 85 us$ including
shipping and insurance. Does anyone have experience with this type of tuned
loop antennae. I've ran RGU-6 coax from my office to the factory roof,
(appx.75ft) as I doubt if the loop would pull these in from inside my office
which is inside the factory.

Is there a less expensive alternative than the loop since I have coax
installed ?

Thanks
Jeff
