Anyone else seeing a problem with H-20 receivers not pulling in decent signal strength? I've had a number of customers doing upgrades from D-10 or D-11 to H-20. The D-11 is pulling 90+ at the on-screen signal meter across the board. After replacing the D-11 with an H-20, the signal strength is showing 50-60 on the screen. It's not a switch problem, or a siting issue. I'm just seeing consistent signal drop with the H-20. H-10's don't have any problems like this. Just wondering if it's me or junk equipment.
