AM Loop Antenna Calculator

Version Adapted for RLC circuits by Marc

Original sources for LC circuit in inches/feet by Bruce Carter, adapted to have more turns .... for Long Wave and experimenting the lower bands ... (I won't say 5000 turns is something I expect you to do, or that it will be practically feasable in terms of conductivity etc)

Just send your postcards/money/shortwave radio's/antenna's (I saw a very nice design with rosewood on eBay) and I'm looking for a cabriolet ...

Standard regulated capacitors are somewhere 9 - 365 pF, so you don't have to change that variable ...

NOTES

  1. Tested and known to work in Safari, Firefox, IE6+, Mozilla 1.3+, Opera 7+, and Slimbrowser 3.51+. Does NOT work in Netscape versions prior to 6!!! Gives garbled output on IE5.2 vMac!!!
  2. Inter-winding capacitance can upset the calculation. If that happens - decrease the number of turns!
