The Low Frequency Receiving Loop

The Spreaders are 3 feet, making the loop 6 feet in diameter. There are 5 spreaders so the windings can alternate from side to side.  There are 30 turns of 18 gauge stranded insulated wire.  The 1x2 spreaders were cut to 3 foot lengths.  Then 1/8 inch holes 1/2 inch apart and staggered 1/4 inch side to side were drill in the spreaders.  (15 holes to a side, 2 sides , 5 spreaders = 150 holes)  Two slots were cut on the table saw in each spreader to hold the wires.  The spreaders were attached to the circular center supports.  As the wire was wrapped around the frame, 1/8 inch fiberglass rod was shoved into the holes and cut off.  The whole thing was made with scrap material and things I have been scrounging.  I use one of Lyle (K0LR) Koehler's balanced preamps on the loop and turn it with a CDR TR-44 Rotator.  I painted the center to give it a tinker toy look.
