Sigh…Umm.. would it be better to use more than 4 winds? Like maybe 8 or 12 winds?
The radiation resistance of a loop antenna increases by the square of the number of turns, while losses increase in direct proportion to the number of turns. Higher radiation resistance with respect to the losses in a loop antenna improve its performance, so 12 turns would be better than any number of turns less than 12 (other things equal).
Here is a link to some homemade multiturn loop receive antennas http://www.mtmscientific.com/loop.html
If you are not looking at this as a construction project you might consider a “Select A Tenna.” I’m not sure they are still manufactured, but I saw some on EBay http://www.ebay.com/sch/i.html?_kw=select-a-tenna+antenna
