All: My shacks location makes it difficult to keep ladder line away from other cables that enter the house. Someone suggested I use 2 runs of RG-11 coax in parallel to route the coax inside the house
Tony, How far is it from your rig to the entrance point? How high in frequency do you wish to go? On HF you can run a short distance with coax and then use a 1:1 or 4:1 balum at the outside side of t

P.S. Two lines of RG-11, 75/2=37.5 ohms. Two lines of RG-8, 50/2=25 ohms. Not much of a difference to worry about. the two coaxes are in series, so the effective Z is twice that of the coax you use,
I have 600 ohm homebrew line outside. When it gets to the house, each leg is soldered to the centers of two pieces of 1/2" hardline (spaced about 3" apart), which pass thru the entry port and then ar
