Thank you for the new reports.

Attempted to trim tree branches on my property.
No improvement on RF 12 reception.

Replaced baluns twice on the 2 stacked y10-7-13s resulted in improvement on RF 7.
Still no lock on RF 12.
Silicondust needs signal quality of 50% or better to lock.

HDhomeRun Config
RF 12
ss 75%
sq 43%

As experiment I converted my vertically stacked Y10-7-13 to a horizontal layout using saw horse next to
antenna mount.
Trial and error horizontal distance between the antennas.

11.1 (RF 12) finally locks with horizontal layout.
Silicon Dust
ss 81%
sq 60%

RF 12 right at digital cliff.
Over time the best spot on roof for RF 12 changed. I may need a separate location and mount for RF 12 longer term :<
Considerable improvement with horizontal array, but you are still behind a hill.

Thank you for the useful conversion chart. Just for fun, I have added dBm values in a Sandbox post.
