My landlord doesn't allow for outdoor antennas. I need to improve my reception. At a later date I hope to have a window mount antenna with suction cups on the window. I need some ideas for the right coax at 850-860MHZ frequencies. I need a 25 foot run with one end having a SMA-F connector and a SMA-M on the other end. It can't be solid core like standard RG-58.
