I spoke with Larry and it seems a number of antennas shipped with a radiator 10-12 feet too long. Either measure your radiator to 65 feet and start from there or fold back about 10 feet and see how that affects the swr. If it draws it much closer to spec, then start trimming it in 4 foot increments to sneak up on the correct length. Let me know how it works out. We apologize for the confusion.
