For the crystal set enthusiast living in reasonable proximity to broadcast stations, the loop antenna has much to offer. It's cheap, portable, and seldom violates local building codes. But, I've also experienced some loop frustration with twisted leads and occasional shorted turns as I try connecting clip leads to closely spaced loop taps. Individual access to each component in the set is an asset during circuit measurements and experiments. Since the dawn of electronics, the phone plug and jack combination have provided reliable connections independent of angular alignment.
All length dimensions are in inches.
Mark the centers, both in length and width, of each strip. Lay out and drill the hole pattern for part A1. As the countersink goes deeper, make shorter cuts and allow cooling time to prevent melting the acrylic. On a flat surface at least 6 feet long, place the end of A1 without holes against one end of A2. Adjust, if necessary, to insure that the 36-inch edges of A1 and A2 lay in a straight line.
