16’ dish From: Mathew Howard Sent: Tuesday, May 16, 2017 10:18 AM To: af Subject: Re: [AFMUG] Does anyone have a 28-34dBi 2.4GHz 2x2 MIMO antenna
Yeah, but what if it doesn't work with the 8' dish? once you have some kind of a link in place, it's pretty easy to get a good idea of what's going to happen when you get bigger dishes on there.

I would want to put up some kind of a test link before I went there, even if it was just a pair of PowerBeams.

If they won’t let me put a 1 or 2’ dish on the tower they run to get extra bandwidth to the school (7 T1’s for 300 kids) or the medical clinic (2 T-1’s), I’m thinking they aren’t going to let me cut down or trim a mile of trees. Everytime I proposed something I was answered with “we have a plan, just be patient”. Not really my strong suit. This plan involves towers but nobody knows who gets awarded or when. So, 2.4GHz through a mile of trees, here I come. I thought of the 2’ dish and see what happens but I don’t want to have to pay tower climbers so do this twice. I’m going to do the 8’ dish on the tower and 2’ dish on the roof. Once I see those numbers, I can make adjustments on the roof. Biggest issue is AF2 through trees. I’m thinking that I’m bringing up a pair of ePMP 2.4GHz radios also to compare. I’m also considering putting up a Cambium 450i 900MHz as backup with a Yagi.

I have asked them to remove trees in a microwave path before and they had no problem doing it. Gino A.

Similar to how they say the AF24 can go up to 10miles, which is effectively bs, the max 99.99% availability reliable range is 3-4 miles almost anywhere on earth that a substantial number of those radios coild be installed.

I can't quite tell if UBNT over states their gain, L-Com understates their gain, or if there is another fundamental difference, but the L-Com 900mm dish is only rated at 25 dBi. I have not used it, but I've been happy with their 400mm unit. http://www.l-com.com/wireless-antenna-24-ghz-dual-polarized-dpd-series-parabolic-dish-antennas -Chris On Sun, May 14, 2017 at 5:22 PM, Eric Kuhnke <[email protected]> wrote: I have not seen one that is anywhere near reasonably priced and can be equipped with a (first party or third party) side shield/radome kit.
