Depends on the application. If you are in an urban area and your customers are within a mile, there will be little difference. With the dropoff, f/b, and no lobes, I'd take this over a standard dual-polarity sector. And since I install in residential areas with aesthetic issues, no shield kits.

I can definitely see situations where these would make sense though, but I think the ones in the 30-60 degree range are probably more interesting than the 90. ________________________________ From: Af [[email protected]] on behalf of Rory Conaway via Af [[email protected]] Sent: Wednesday, October 15, 2014 10:21 AM To: [email protected] Subject: Re: [AFMUG] Rflelements announcement I think the key thing here is the f/b ratio and the pattern. 10dB is fine if you are using DFS frequencies anyway.

So a typical horn is about as good as the best patch array or a smaller parabolic reflector. But they are worse than both in the mechanical sense. The higher the frequency the more practical horns become. From:Stefan Englhardt via Af <mailto:[email protected]> Sent: Wednesday, October 15, 2014 1:51 AM To:[email protected] Subject: [AFMUG] Rflelements announcement This is realy something I did not expect: They announce Systems with Horn antennas. A quite different approach. Their sectors are directional antennas so coverage is not as good as with traditional antennas (Their marketing argues the opposite). But horn antennas should have very low sidelobes, a good FB-Ratio and allow small angles. So it should be possible to make a more dense deployment. What make me scare is the big opening where water and ice may cause damage.
