Antenna Wire Inside Grounded EMT AC8UR on 10/3/20
Two antenna wires are connected to RG8X inside a jbox mounted to the side of an aluminum sided house. The jbox is 6ft above the ground. A vertical 10ft EMT pipe is connected to the jbox. The pipe is grounded because it is adjacent to a power line running vertically to the 2nd floor and put a lot of noise in the antenna. The wires exit the EMT 16ft above ground and are tied off to two trees in the yard unfortunately at only about 75 deg apart, a sort of lateral V. HOA issues so can't be real obtrusive.

The question is how to treat the 10ft sections of wire antenna inside the grounded EMT. The antenna wires are connected together inside the jbox, tie to RG8 at that point, and probably cross more than once inside the EMT. I assume it is to be treated as a type of plain feeder line and not part of the antenna. Better results with direct connect to RG8 rather than via balun. Any advice here?
