Ah, I see. So far, we've nod had any issues, but with the addition of my HF rig at 50W or so, it was trying to forestall issues.

For what it's worth, our antennas are on opposite ends of the house. I got my FT840, and he's using an Icom 746. He's a tech, so only 10M HF for him (until I motivate him enough to go test out).
