I recently installed an HF station in my coach and am quite pleased with the results. The noise level is low, here in the countryside of south-central NC and DX has been quite easy to work. I was able to use 2 pieces of coax through a hole in the wall under the desk to route the balanced line into the shack. The radio is a Yaesu FT-450D into an MFJ-974HB tuner. The antenna currently is a 125' insulated doublet fed with about 75' of 450-ohm window line hung in the trees at around 35'. I used my longbow to place the antenna support ropes, with decent success. I will have to do something for when we are away from home, but that will come. I may go with a Scorpion screwdriver, with the sturdy steel supports that are used to frame the roof structure of the coach.
