In heavier rain zones, being able to use dishes as small as 3 ft in 6 GHz has been a game changer. Back when FCC minimum was 6 ft dish, that was not feasible on many sites, due to structural issues or tower rent. Rain fade much less of an issue at 6 GHz, but need to watch out for multipath similar to 5 GHz.

If you can design for ACM and rain fade, yes. I know the typical afmug purchase considers them too pricey but there are lots of high quality, dual polarity 4' and 6' size 18 GHz dishes. I would not be excessively scared of 15 miles at 18 GHz with big dishes. On Wed, Feb 8, 2017 at 5:42 PM, Mike Hammett <af...@ics-il.net <mailto:af...@ics-il.net> > wrote: Not a chance at 18.

I need to be able to get 500Mbps at about 15 miles. Is that possible with either of these? What kind of real world speeds can I expect out of these and what channel size do I need to license to get those speeds? Is there something else I should consider? What brand/model radios and dishes, what other frequencies for easier licensing, etc? It would be great to be able to get a gig that distance, but I'm trying to be realistic and get just what I really need to start with. No legal advice please, just your experience with it and any knowledge you'd be able/willing to share with the licensing of these frequencies. Thank you, Brett A Mansfield
