Nope. They are much more complex than antennas that make use of radials.

I worry a bit that the Ubiquiti omnis I think are only spec’d down to 5.4. We tried an International NBE-M5-19 set to to a different region code (Czech Republic) to get an idea what the performance would be once the FW came out, and could only get about –70 at 1700 feet with the 10 dBi omni on the M5 Rocket. Yes, it works, but that’s not going to be very robust, and that’s only 1/3 of a mile.

I question whether that’s really a 10 dBi antenna though, the range has been disappointing.

The site is currently 2.4 FSK and an omni with 7 degrees downtilt, but the 2.4 interference has become too bad. I have been trying to use Rockets in U-NII-1 with the Ubiquiti 10 dBi omni, but the range is really poor plus I’m tired of waiting for the SOON firmware for the Beams. I also see home routers now coming preset to use channels 36-48 by default (which makes sense), so U-NII-1 may not stay quiet in town.

And has anyone used either of them? My experience with 5 GHz dual pol omnis has been disappointing, I'm wondering if these bigger, more expensive omnis deliver better performance. 11 dBi isn't much if you can lose 3-5 dB at certain azimuths, another few dB depending on frequency, and another 3 dB at zero elevation due to 4 degrees electrical downtilt with an 8 degree beamwidth. For $600+ and 6 inches diameter, I'd expect it to wash and wax my car.
