Between 50-80GHz, oxygen attenuates the EM spectrum significantly more than water. Not to say that it doesn’t contribute at all to fade, but at 300 meters you’d probably only ever go down if Poseiden himself took offense to your client.

I just read an article claiming that the atmospheric attenuation at 60ghz is so great that at any range where 60ghz will operate the rain fade is insignificant. ------ Original Message ------ From: "Carl Peterson" <[email protected]> To: "[email protected]" <[email protected]> Sent: 10/19/2017 2:58:56 PM Subject: Re: [AFMUG] IgniteNet Metrolinq Yes, and the LR brackets. They should just drop the regular bracket and make everyone order the decent ones.

Very happy with them. The mounts they come with are trash. Get the “long range” brackets and alignment scope.

Have any of you tried IgniteNet? Has it been reliable for you? I don't actually need a gigabit in this case, I just need it to be up. -- Carl Peterson PORT NETWORKS 401 E Pratt St, Ste 2553 Baltimore, MD 21202 (410) 637-3707
