[Lowfer] L.F. LOOPS

[rick]

Hi all,
 I was just looking for opinions on feedlines for small loop antennas.I built a 3 ft square loop with about 24 turns .I plan to to tune it from  about 160 -500 khz. It wil be placed outdoors.I havent decided how to feed it yet.Should I link couple or direct couple it?Should I coax feed it or use twisted pair.? I have some nice 22 ga. shielded twisted pair.
 I will also be remote tuning it using varicaps.
 Any input would be greatly appreciated.I have read too many loop articles recently only to become more confused!

                              Thanks
