@dsj does that mean I can turn SKY - Mobile back to true north now?

FWIW, here is a picture taken from the field on the west side of my house. The SKY - E Kelso (5075) is on the taller pole (8’ vinyl coated wooden closet rod) and SKY - Mobile (5080) is on the shorter pole (~5’ repurposed fiberglass pole). The ridge of my house runs true north-south which makes for aligning the SKY really easy.
