I have a dipole antenna in the attic. I had the same problems on a few bands, but not all. I added a 1:1 choke balun in the feedline and it removed the problem for me.
It sounds like RF is not getting back into the shack, and a choke balun placed at the antenna will fix that.

After a maintanance on my antenna when I connect HRD to my Laptop I face this problem on 10 MTS Only
The software gets disconnect when I tune the ntenna with my LDG AT-1000 Pro autotuner. This happens only on 10 mts. SWR is well below 1:1.5
I tried my best to locate the problem but could not succed.? Is it a RF leakage if so what can be dome I tried few ferrite beeds along all the doubted cables but of no use
My antenna set up is Inv V with l600 ohms adder line feeder connected to 6:1 Balun and then to CMC balun and to rig
What can be the reason ? what is the remady ?
