Meet the *MIMO EX* and *DuplEX *series of 5GHz dual polarity dishes from Jirous. The only series of 5GHz dual polarity dishes that approach current* ETSI "Class 2"* specifications. "Class 2" antenna designs provide improvements in several areas, including: - *Throughput* - *Stability* - *Distance* *WISPA Members use the coupon code below to* *Get 25% Off your first order!* [image: JRC 29 MIMO EX]<http://www.brinknetworks.com/jirous-jrc-29-ex-mimo/?utm_source=WISPA_Mailing_List&utm_medium=Email&utm_campaign=MAY_2012> <http://www.brinknetworks.com/jirous-jrc-29-ex-mimo/><http://www.brinknetworks.com/5-8-ghz-dual-polarity-parabolic-dishes/?utm_source=WISPA_Mailing_List&utm_medium=Email&utm_campaign=MAY_2012> [image: hr1] [image: screenshot2]<http://www.brinknetworks.com/jirous-jrc-29-ex-mimo/?utm_source=WISPA_Mailing_List&utm_medium=Email&utm_campaign=MAY_2012> *Additional "Armor" NOT Required* It's true that expensive aftermarket "Armor" may provide much needed side-lobe suppression - unfortunately *It doesn't improve front to back (F/B) ratios*. In addition to the side lobe suppressing collar, or shroud, Jirous MIMO EX and DuplEX dishes have *F/B Ratios in excess of 43dB. Compare this to the popular "Class 1" model's F/B Ratio of only 32dB*!

Jirous feed horns are precision-machined works of art, engineered to deliver superior radiation efficiency. The advanced design of the DuplEX feed horn (shown above) allows it to achieve *53dB port-to-port cross polarity isolation.* [image: hr1] *Ideal for those tough Ubiquiti™ PTP Links* [image: hr1] With optional RP-SMA connectors Jirous dishes provide an excellent solution for those crowded co-location spaces.

However, as the deployment of unlicensed 5GHz equipment continues to proliferate, the interference-prone frequency characteristics of "Class 1" antennas expose essential backhaul links to slowdowns and costly downtime. Brink Networks is committed to helping wireless network operators get the most out of their networks. Helping operators be aware of the *European Telecommunications Standards Institute (ETSI) *antenna design specifications is a significant step in the right direction. The specifications' exact wordings can be found using the links below - In summary: - "Class 1" specification is intended for antennas that are designed to operate in environments where there is a "*low interference potential."* - "Class 2" specification is intended for antennas that are designed to operate in environments where there is a *"high interference potential."* The most *significant difference* between "Class 1" and "Class 2" antenna requirements is the* suppression of close-in side lobes.* The rectangular azimuth ("E" plane) plot below demonstrates the differences in side lobe characteristics between competing "Class 1" antenna designs and the JRC 29 EX MIMO antenna.
