Shielded loops are needed only when a small loop is used for
direction-finding purposes. It is then an angle-measuring instrument.

Shields serve no useful purpose on ordinary receiving and transmitting
loops. They reduce efficiency. All that is needed is a bare loop
conductor.

For multi-turn receiving loops download program RJELOOP3

For transmitting magloops download program MAGLOOP4 from website
below. Download in a few seconds and run immediately.
