Which way should the resonant frequency go as the height above ground is increased for a 40 meter rotatable linear loaded diopole. If the swr is 2.0 to 1 at 7200 with the length set for 7200 10 feet

Van: A similar question was asked here a few years ago regarding tuning a tribander close to ground. The concensus of opinion and experience, I believe, was that the resonant freq would increase as t

Ten feet is a bit low for tuning. A 40 meter dipole tuned at 15-20 feet will resonate about 10-15 KHz higher at 78 feet. Keith WD5DXL Which way should the resonant frequency go as the height above gr
