Completed my coaxial dipole (1/4 wave center conductor, and 1/4 wave shield wrapped back over the jacket like a sleeve) and taped it up in the window. Was receiving planes out to about 60 miles using the 5 ft of coax, Not bad. Got my 50' of LMR400 with N connectors today. Mounted the antenna inside a 1/2 piece of PVC tube and sealed both ends, stuck it up on the peak of the roof at 30', and connected the coax. Went back inside, and already I am getting planes out to 150 miles or so, and the antenna is just laying on the roof at the moment. Think this will save me some money.
