KL7JR describes the antenna in detail: total length of each leg of the antenna is 17 feet long (each 2 inch diameter coil, one per leg, measures about 14 feet of #14 solid insulated wire). I find the solid wire easier to work with and form the coils. I made the coils larger to better utilize the space I had (hmmm will that work?). My windows were of the new high efficiency plastic style which afforded me a lot of glass and not much metal framing to worry about interference. My LDG-100 auto tuner easily tuned 10, 12, ...
