Sounds like RF current on the shield when on the antenna and not on the
dummy load. I suggest a 1:1 UNUN balun between the amp and the antenna.
I've had good success with a product from The Wireman being model #8232.
Certainly worth a try.

Subject: [TenTec] Built in SWR meter bannans
I have a Tec Tec Auto Coupler that is turned off and a Ten Tec Hercules II
at full power. The SWR bridges in side the equipment reads well over SWR
over 3:1 on certain bands while my BIRD Watt meter read 2:1.
ALL SWR meters is at 1:1 into a dummy load so that rules out the BIRD is
whacked.
This problem seams to mainly happen on 160M however I have seen it do this
on different bands with other antennas in the past.
Are the diodes going into saturation? I am going BANNAS with this issue.
