[Lowfer] Copper pipe loop question

[John Bruce McCreath]

Hi Guys…..thinking about building a copper pipe loop antenna about 6 feet square,
to use as a broadband receiving antenna.  I’d use toroid transformer coupling, with
the pipe making just one pass through the hole.

I have a pair of 2 inch cores of unknown material (no colour) that I stacked together
and wound 47 turns of #14 magnet wire in a single layer as the secondary.  I took a
reading of the inductance with my LCR-55, which indicated 6.7 mH.

Before I spend the money on the pipe, do you think this would work?  I did the math
based on a Z-ratio of about 2200:1 and the loop having a reactance of 0.25 ohm, it
works out to about 550 ohms, which would be fine with a window-line feeder.
