Reference my earlier post, my 80M dipole shows a 1:1 SWR at ~3800. With
the 238 in BYPASS the SWR shown on the external meter is 4:1. Antenna is
fed with ~75 ft of RG-213. The tuner will easily match this load at 3550.
In looking at my "tuning chart" this configuration will attain a match on
all bands except 160M.
