Hey guys, I am planning my new shack in the side room off the living room. I have an existing Star Duster copy about 20ft up on the corner of my detached garage with 100ft of LMR 400. About 50ft of coax is zig zagged and attached to the rafters. If I were to run coax to the new shack, it would be right around 250ft between the garage and the house so maybe 300ft of coax total. Would this be too far and would I be better off putting a pole up the back of the house so it can be closer? Any and all replies welcome. Thanks!
