Lou:
I am indeed taking the SWR readings with the meter between the rig and the
antenna, but I don't have an LDG TW1. I am using a talking SWR meter that
originally was made by a guy named Remy Simmard out of Quebec, Canada.
When I connect the SWR meter, one side of the meter module is connected to
the rig, while the other side is connected to the antenna.
When the antenna is tuned using the internal auto-tuner, this SWR stays
about the same, although the actual meter on the rig reads 1.1 to 1,
probably because of the internal tuning that was just done by the
auto-tuner.
