Some pictures of the RF elements A Symmetrical horn and it’s components.
We recently headed up a job for a client of installing some RF elements horns, Cambium ePMP, and Baicells LTE for a client. One of the gems of this job was the frame the client designed for the job. We can’t take credit for this. We just think it’s cool. Some of these pictures were taken during construction, thus post clean-up.
The frame is truly an example of how WISPs are stepping up their installs to become more standardized and carrier-grade. It costs some money but is worth it in the end.

Due to the frequency challenges, we decided to upgrade the dishes to RF Elements Ultra Horns.
If you recall our spectrum looked like this before.
After the horns. While not a night and day difference you will notice several improvements across the band. Less red and yellow on the scan and sharper drop-offs. We saw the most improvement in the 5160 area and the 5720 ranges. And this is with the horns pointed right at the source of most of the 5GHZ noise. Not much you can do if you are pointed right at the noise.
What did this mean for the link? It meant we were able to find a 200 meg increase because we were able to obtain better modulation on the link.
So while we were not able to filter out all of the noise we wanted, we were able to increase our MCS rates on a very noisy link to increase bandwidth and increase the reliability of the link. Before the horns, the MCS rates would be in a constant state of flux dealing with noise.
Downlink RSSI: -59
Antennas: RF elements Ultra Horns
Downlink Ratio set to 75/25
Question: Why are you not using channel bonding?
A)Having some reliability issues with channel bonding at the moment on the 550 platform.
Question: What was the link like before the horns?
