Dan,
What you were doing was clearly loading the transmatch, as the arcing
indicated! There are two positions on Tee tuner circuits as this was, for a
swr dip, and one is more tuner loss than the other. And many Tee circuit
tuners sold today, do not have enough capacitance or inductance to get
optimum LC ratios, and thus good Q on the lowest couple of bands, or very
short antennas for a given frequency. Used properly, a Transmatch should
have no noticeable loss to your signal. Sometimes, it is the choice of a
particular antenna and the particular and inadequate transmatch.
There is a lot of merit in getting as good a match at the antenna to feeder
as you can, unless you are using open wire or ladder lines that are suited
to operate with high SWR on the line and still be low loss. Coax, though,
really does not work well with high SWR over 3:1. It is lossy when
mismatched, and very sensitive to line length.
