for receiving and transmitting. I had a 40M dipole with trap coils between my balcony and two adjacent buildings even, once. Hey Scott, do you know a place where I could get simple instructions for an AM loop antenna for a modulation monitor? I have a surplus TFT 713 and would love to use it to pick up 630 WMAL at home. Belar wants $345 for one of their circular antennas but I'm sure I could build one cheaply with some PVC, wire and some caps, right? The Toys for Tots should be fine with just a long wire attached to the input. The loop antenna will have lower gain but higher directionality. The real deal with the loop antenna, though, is that the gain on it is calibrated and you're paying for the accurate calibration of a measurement device. You don't want a measurement device, you just want as much gain as you can get. Dave Sproul, Bethesda. MD Since Hardin and Weaver are gone, there's no reason to listen to WMAL. But I am up in your neck of the woods on a monthly basis if you want to bring it over and try it with a wire. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |
