Daniel, what kind of range do you get with 4’ antennas at 24GHz? Rory

SAF has their Integra 24GHz FCC certified with 4ft antennas even.

Just Canada or other places.

I also suspect that high perf dishes would allow for channel re-use without sync. I really can't do 24ghz more than 3 miles in any case, so it's pretty rare that we're using any of these things to start with. So I don't have as much experience with that as some of you do, and maybe my opinion is not well informed.

Which is probably about the same pricing as the Stratalink, although ~half the speed being that it's only 256QAM. Neither of these seem reasonable to me when the AF24 exists. Yeah, the AF24 uses the whole 200MHz, but at least you can sync them. On 10/15/2015 1:44 PM, Bill Prince wrote: Yes. Midwest maximum rain rates are way up there. Looking back in our records, our AF24 (not HD) have lost ~~ 3 dBm during our last real rain event last December. These are 2.25 mile links. bp <part15sbs{at}gmail{dot}com> On 10/15/2015 11:38 AM, Eric Kuhnke wrote: The funny thing about the pacific northwest is that it's only ITU rain zone D. We get constant rain and drizzle and grey skies that causes acceptable fades (like, an 18 GHz link that normally sites at -37 with no rain will hang out at -49 for days at a time), but major downpour events are relatively rare. It's the mm/hour... If I recall correctly some locations that are less famously rainy such as Baltimore or Chicago actually have more frequent high mm/hour rain events than Seattle. Thus a link designed to be at max capacity for five nines will be shorter in Chicago than in Portland or Seattle.

For the last 4 years we haven't even gotten that. I know of a couple situations that are getting almost 10 miles on a AF24HD. bp <part15sbs{at}gmail{dot}com> On 10/15/2015 11:31 AM, Eric Kuhnke wrote: 5.5 miles is probably asking too much, I would use it at a max of 5-6 km in a Pacific Northwest rain zone. ________________________________ [Avast logo]<https://www.avast.com/antivirus> This email has been checked for viruses by Avast antivirus software. www.avast.com<https://www.avast.com/antivirus>
