In an ATU (AMU) we have caps and coils, same with many antennas that need a coil or an L match.
In some of the worst matches that people use an ATU for what can be the ranges of internal coil losses in dB ?
As an example of a very inefficient match I have a 160m band antenna 11m of vertical wire, it is a coil of a bout 38 turns on a 6 inch pipe. I am going to guess that the coil losses might be 12-15dB loss or possibly more. I estimate 100W in will probably produce about 5W radiated. A good coil match example can be that of a 5/8 wave or a 1/2 wave CB vertical antenna.
Does anyone have some ranges of potential coil losses in dB that could be expected matching difficult loads.
