I received my new Heathkit catalog today, in which there appeared a new product: a fairly low-cost VLF converter kit. I would appreciate references/suggestions as to a suitable receiving antenna for VLF (10-500 KHz). I understand that loop antennas are popular. Thanks! Bruce (K1FFX)

My favorite antenna for general tuning around on VLF, LF and HF is an active whip antenna (untuned). It is basically a J-FET follower direct coupled into a PNP. My whip is about 3 feet long (anything much longer and I get broadcast overload). I once tried a large untuned shielded loop by throwing a length of RG-58 coax over the house roof. The ends were brought in a window and properly connected to the rcvr. This antenna worked quite well, too. Bob, K9EUI
