The Rocket M5’s seem to vary the power output about 21dBm based on the modulation rate which makes it difficult to determine what’s happening. And the NanoBridge’s do that above 18dBm since they are lower power and based on bench tests that I’ve seen, power output numbers might be optimistic. I got suspicious when I compared a Powerbridge-25 to a Rocket M5 with the 30dBi antenna and the Powerbridge was slightly better on a 10 mile shot. Since my Jirrous antennas are on AF5x radios, I’m more comfortable with my guesses but they are just that.

But anyway, I just tested it on various channels, and I'm not seeing any significant difference on 5.2ghz. on 5225, It was 1-2 db weaker than what I saw on 5735, but 5840 was slightly weaker than 5225, so I'm not sure how much that means... none of the channels are particularly clean (this link normally lives in the DFS band).

In 5.2GHz, my gut-o-meter says they are probably down about 5 dBi.

This is what they said. I think once translated into English it says they'll have new versions of their antennas with similar performance to what they have now that supports lower 5 GHz in a few months. ----- Mike Hammett Intelligent Computing Solutions http://www.ics-il.com [http://www.ics-il.com/images/fbicon.png]<https://www.facebook.com/ICSIL>[http://www.ics-il.com/images/googleicon.png]<https://plus.google.com/+IntelligentComputingSolutionsDeKalb>[http://www.ics-il.com/images/linkedinicon.png]<https://www.linkedin.com/company/intelligent-computing-solutions>[http://www.ics-il.com/images/twittericon.png]<https://twitter.com/ICSIL> Midwest Internet Exchange http://www.midwest-ix.com [http://www.ics-il.com/images/fbicon.png]<https://www.facebook.com/mdwestix>[http://www.ics-il.com/images/linkedinicon.png]<https://www.linkedin.com/company/midwest-internet-exchange>[http://www.ics-il.com/images/twittericon.png]<https://twitter.com/mdwestix> ________________________________ From: "Wi-Fi Jirous" <[email protected]<mailto:[email protected]>> To: "Mike Hammett" <[email protected]<mailto:[email protected]>> Sent: Tuesday, May 5, 2015 9:24:17 AM Subject: Wi-Fi Jirous Hi Mike, thank you for your mail. We plan prepare new revision of our parabolic antennas - what will cower the wide range of 5 GHz frq. in similar prerformance as the declared range now - inmediately, after we will have built our new measurement equipment, what is now in process of synchronisation of software electronic and mechanical parts. This solution help us be more flexible by developing of antennas in future. The launch of measurements on this new equipment is estimated in few months. Thank you, that youre interested in our products and have a nice day, Csaba
