DIAMOND-WEAVE 660/46 LITZ COIL FOR CRYSTAL RADIO SETS
FREE SHIPPING WITHIN US - AKA Spider web coil – Two 1N34A diodes included, and mounting bolt, nuts, FREE!
Free Shipping within US. This is a Diamond-weave crystal radio coil hand wound by myself with 660/46 litz wire. The design is sometimes mistaken as a spider-web coil but since it has no internal spokes, it is called a diamond-weave.

. See photos. Wooden stands are shown for demonstration purposes only and is not included.
There are no forms, this air-wound coil is held together with Q-Dope and sprayed with clear acrylic to strengthen the coil.  Lead length is approximately 6-inches, and pre-soldered. This coil wound using a 15-pin former, a 36% increase over an 11-pin former, meaning more crossovers for better inductance performance, less inner capacitance.
A 3.0-inch nylon screw and 3 nylon nuts are provided to mount the coil on your set
. Coil measured for proper inductance using an AADE L/C Meter IIB precision meter. See photos.
Coil Dimensions:
Coil ID:           1.8750-inches
Coil OD:         5.20-inches
Coil width:      .3750-inches
Inductance:     280.0uH
This coil is new and sold as-is. Prices charged depend wholly on the cost of wire used, and postage costs. WØHII Coils are always well packed in its own plastic container, with bubble wrap bag and shipped within the US for free via USPS Priority Mail.
