You will need a broadband omni. Not probably V pol. Slant pol would pick up both. Omni slant pols are not easy to make. Nor are H pol omnis. Broadband H pol omni could be especially difficult.
I guess an array of bow ties combined could do the H pol and a double cone or a disk cone could do the V. What are others using for this?

Whats the price per unit built? Could afmug do a small money drive to fund a production run and get us access to some of them free sensors <insert "yall got any more of them sensors" gif here>? speaking of money drives, is it time for a mailing list funding drive?

The RTL-SDR dongle used on our sensors has a limited frequency range between 24 and 1766MHz. This is already pretty good, but more interesting bands can be found above this limit. For this purpose, we have created an extension board that enables us to scan frequencies up to 6GHz which includes common ISM bands with lots of applications. Where does one get such extension board? ----- Mike Hammett Intelligent Computing Solutions Midwest Internet Exchange The Brothers WISP -------------------------------------------------------------------------- From: "Brian Webster" <[email protected]> To: "AnimalFarm Microwave Users Group" <[email protected]> Sent: Friday, December 6, 2019 10:24:31 AM Subject: [AFMUG] Live Spectrum sensing network open source project Some time ago I learned about this project. It is basically a network of software defined radios listening to the RF spectrum and reporting back to a central database. I think it would be cool if every WISP could build one of these devices (cheap pi and RTL-SDR dongles) and place them on each of their tower sites. The project is bigger outside of the US so if the WISP industry could get a critical mass of sensors deployed, it could turn in to a real time spectrum use map and data tool. Matt Larsen has always pined about how the cellular carriers have been spectrum hoarding. A system like this could actually prove it. Imagine being able to map all the areas where there is absolutely nothing going on in the spectrum they hold! Being able to argue these points with real time data gathered over time could be huge. This might also allow organizations like WISPA to argue for more opportunist use of underutilized spectrum, especially in rural markets. The reality of the US spectrum policy has always been about what is needed in the top NFL cites. Remember that about 92% of the US population lives in only 8% of the land area. Let’s mobilize an effort to make better use of spectrum over the whole county. The FCC is already on their way to doing this, the databases are in place, what is lacking is the widespread sensor networks. https://electrosense.org/ Thank You, Brian Webster www.wirelessmapping.com www.Broadband-Mapping.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com ---------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com -------------------------------------------------------------------------------- -- AF mailing list [email protected] http://af.afmug.com/mailman/listinfo/af_af.afmug.com
