Has anyone used Gold SADD56030-DP dual polarity dish, is the gain constant over 5Ghz band and is build quality OK, is the mounting bracket suitable for windy exposed locations, any opinions on this is most welcome.
The Mounting bracket is not strong enough…
Yeah the mounting bracket does appear not to be strong enough, with high wind loading on a exposed high site it will fail.
Jirous have an excellent 29dBi dual polarity dish available, with nice strong brackets. http://en.jirous.com/antenna-5ghz/jrc-29-dx-pr
They also have a 32dBi version but its not on the website yet, email your local distributor for pricing.
Looks good but Frequency range 5,45 - 5,9 GHz, pity it wasn’t 4.9 to 6ghz
We’ve deployed Jirous dishes throughout our network and although the specs say they only go from 5.4 to 5.9 - they operate quite well from 5.1 up to 6 Ghz.
Regarding the wind resistance - our WISP operates in Tornado Alley - Aside from tornadoes - Straight line winds from storms in our area can exceed 80 MPH (129 kph) we have almost two dozen scattered in a 50 mile radius and haven’t had one budge or break.
Others have had the same success…see the replies in this thread - http://forum.ubnt.com/showthread.php?t=41321&highlight=jirous
We deployed this PicoPOP last week using the JRC-24 MIMO dish, a JE-300 enclosure and Ubiquiti 2.4 Omni.
Jirous’ specifications show 5.4 to 5.9…but the access point it’s pointed to is running at 5280. For the curious the AP it’s connected to is an RB-800 with SR71 & UNBT MIMO Sector about 4 miles away.
There are 11 other clients in addition to one the BTest is running to - so you’re seeing PTMP results (notice 72 MB total throughput vs…62 for the client.
In addition the DupleEX series, Jirous has developed a MIMO and EXtreme MIMO series.

Disclaimer: To those that don’t know - We’re Jirous’ distributor in the US. The story is that we also run a WISP and after pleading with our distributors to carry their products in the US and having no luck - we felt other WISP’s deserved to have access to them and started Brink Networks to get the job done.
I would say without any doubt what so ever that the L bracket shown in the pictures would not last the test of time at our location because of consistent turbulent wind and constantly changing direction
