Welcome to the hobby Russel! You can use it as is. Keep your runs short. Good quality RG6 has much lower losses than RG-58 and RG-8X, but is lossier than your better 50 OHm coax. It would be better on HF into a resonant antenna. If you can afford better coax, by all means, buy better coax (LMR-400). If you are like me and money is an obstacle, Run whatcha brung! I don't know what your support base is down there, but if you need to feel free email me. firstname.lastname@example.org I'll be moving to Macomb on Oct, 1st, I hope to hear you on the air.
