I have been out of radio for a long, long, time. Over the years all my equipment has disappeared. A few days ago I obtained a Yaesu FT857D. In trying to get it going I realized I have no antennas no coax no.. Nothing. A guy did give me some RG-14A/U a good 12v marine battery and I did have a charger. The coax is in good condition and I can find some wire to make an antenna. Is this coax worth finding connectors for and using? I suspect it came off an old microwave system? Would it work on 2 meters, 440 or HF? Should I just dump it and get something else? Open to suggestions? Again I have been out of radio for a very long time.
