  1. Here is our webinar "RF elements Noise Rejection 101" done in cooperation with Streakwave on 10/18/2016. Below you will find all unanswered questions from that webinar. Questions and Answers: Can I have two 5GHz radios on the same channel (such as channel 100), 5 feet apart, faced in two different directions? Vertical separation vs. Horizontal separation? How many db down vs. Traditional sector? 5 feet apart shall work fine Would you have an example of what the signal strengths would be comparing the different sectors? Traditional sector I'm shooting for 60's, so I would suspect the signal would be better with less power Our Symmetrical Horn antennas have very precise radiation angle so the drop of the signal outside the main lobe is very steep: So not in every case you will see higher signal strengths. In those cases you will see possibly lower signal strength but more stable modulations rates. Are antenna patterns for Radio Mobile available? Find your antenna, than go to the download page and pick "antenna files" http://www.rfelements.com/products/wireless-broadband/symmetrical-horn-antennas/download/antenna-files Are there any plans to make antennas in 3GHz? We are looking into many new frequencies. So does your antennas have a built in RF armor? Horns? For gods sake no! Their radiation properties do not require additional shields. Ok, i have a question regarding the horn antennas, using ubiquiti radios , what would be the selection that i have to do on the antenna list that the radio has? Use the closest gain / radiation angle that is available Horns are only 5GHz? Yes, full band Hi, what about wind survivability? We just went thru a hurricane matthew. Our current sectors survived the CAT4 winds. Some dishes like UBNT rust at the edges. Our antennas are made of aluminum and stainless steel. Our horn antennas are very compact, wind survival shall be better than some towers. What is the quality and survivability Built like a tank. Only reported damage was a few radomes damaged by really heavy hailstones. And yes, they will not survive a 100 feet drop What makes the symmetrical antennas better than using an isolator radome on a standard antenna? Horns are better because the radiation pattern has no side lobes, only one main lobe of radiation. It does not require an isolator - there is nothing to isolate to/from. The fact that other antennas require them should tell you everything. How does the antenna work in NLOS (near-line of sight) for 5ghz. Is it for pure LOS or can we get some NLOS from it? Our antennas are for 5GHz so the same laws of physics apply. It may be better in NLOS, but you will have to test if its better for you. Is there a space for the GPS puck for the Cambium epmp GPS synch aps? No. You will have to mount the GPS antenna on the tower or your mast or a mount. Are those mounting hardware stainless steel or galvanized materials? Handle salt air They are all Aluminum and Stainless Steel. We do not use any galvanized materials. How do the fresnel zones compare with the regular parabolic antennas? Fresnel zones depend only on frequency and the distance between radios. It does not have anything to do with the type of antenna so the fresnel zones will be the same. Can the horn be use for wifi hotspot? If you run a 5GHz wifi network, then yes its possible. We do not recommend the use of high gain AP antenna for wifi hotspots. What is max distance to install the UltraDish? Many things in the equation. Please use the link calculator Can Ultrahorn fit on Cambium products? Any twistport adaptor can fit any twistport antenna. At the moment we have twistport adaptor for epmp1000. Check: http://www.rfelements.com/products/wireless-broadband/twistport-adaptors/twistport-adaptor/ Plans for other freq's for horn? We are looking at many new frequencies. We use RF carrier class sectors, with rockets M5 inside RF shields. On the same tower, ... How close can we have them together? You should always seek as much separation as possible. Our Carrier class sectors are great for co-location. If we were to replace a 60° or 90° sector say by Cambium epmp series. What would be the equivalent antenna to look for? We are looking for a 60° to be installed on the same tower leg but pointing say due west. We use link planner and am concerned about the distance to calculate the distance. Though we are looking at about 3miles. For 3 miles - pick whatever beam width suits you. Do you have a link calculator? No. As many people would probably like it, we will think about doing one. Will you consider it helpful? Given the "Hard 30º, 60º, 90º" characteristics of your Symmetrical Horn antenna. Are there any guides as to how to mount install these? You have a few degrees before the edge drops off. If you have to precise coverage we would suggest you use 40deg Horns in place of 30’s or 70deg Horns in place of 60’s for example so you have space for overlap. Do you have any 900 MHz antennas? No
