Generally 3' dishes, but when that fails, I ask what could be changed and not even 6' SHP dishes would meet the interference objectives.

I've only had luck getting 2x 11 GHz links anywhere from a N-S link in western Kane County to links over in Will County and the whole area between. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com ----- Original Message ----- From: "Ken Hohhof" <[email protected]> To: [email protected] Sent: Monday, February 16, 2015 11:25:05 AM Subject: Re: [AFMUG] 2 - 5 mile links Define “here”. Aurora may be difficult, but not DeKalb. Also depends on direction, height, and beamwidth. Earth curvature is your friend. I have 6 links in 11 GHz and have never had a problem with frequency coordination. It is frustrating though when you see a PCN from a carrier or utility for an 11 GHz link that is only 1 or 2 miles.

Depending on frequency coordination, antenna size constraints, and desire to use common equipment across your network. 23 GHz licensed is allowed higher EIRP than 24 GHz UL and will go farther, so at 2 miles I would definitely consider it. But like someone said, run the numbers. And assume historical rain data may be optimistic, unless you are a climate change denier. We seem to have several 100 year storms per year now.
