That is what I use. I use it nearly exclusively for my complete station. Have to use crimp on connecters because it has aluminum shield. If it gives me any mismatch I just trim the length. Remember if the feed line is cut to an electrical half length the input impedance equals the output impedance. The stuff I use I purchase from a local hardware store. It is sold for satellite TV hookup and is rated for up 2.5 GHZ. Cost locally is about .10 cents a foot. Just do not try and use high power while transmitting with it.
