SWR is very high and it seems to be not adjustable to the same 1:1 of the first antenna. Why? Different diameters of conductors, different dielectric relationships, that is why. This leads to different dimensions for the same resonance. Larger conductors resonate at lower frequencies (or at shorter lengths for same frequency). More dielectic also shortens resonant length. Just how much, is for you to discover through experimentation. 73's Richard Clark, KB7QHC |
