From some of the statements and questions about my favorite no-tuner matching system, I gather that some people don't understand the benefit of being able to change the length of the ladder line to achieve minimum SWR. Fortunately, one doesn't have to understand how it works - just that it does work. Before continuing with my no-tuner 39 foot rotatable dipole for 30m-6m, maybe a matching example would help. The 39 ft dipole wire is resonant on 12 MHz but that is irrelevant. It's equivalent to a 1/2WL dipole on 30m and 20m and behaves like a EDZ on 10m where it is 1.2WL long. It is fed with 48 feet of "300" ohm ladder line plus whatever selectable length of loops are switched in by the Ladder Line Length Selector (LLLS). For this illustration, we will switch in zero to eight feet so the feedline will vary from 48 feet to 56 feet. The following graphic illustrates what happens between 12m and 6m when we vary the length of the feedline. To avoid making the graph too busy, the measurements use only the even lengths but odd lengths are also possible. We should choose 7 ft for 12m, zero ft for 10m, and any length for 6m depending on what part of the band we are on. Please note that as we step from zero to seven feet on the LLLS, the same dip in SWR moves from 10m to 12m. A selection of two feet will result in minimum SWR on the CB band. Please feel free to comment and/or ask questions about this method of matching.
