I've converted a satellite dish into a WiFi antenna and it seems to be working pretty well, but it presently has a foot long cable running from the little double diamond antenna head to the router. This isn't terribly practical for permanent installation! Here's my question: normal LMR-400 coax for a WiFi antenna seems really expensive. Is it possible to use some other type of coax, such as RG-6 that is cheaper and more readily available as an alternative?
