 Hi, I'm Mr. T with R of Elements and I will introduce the symmetrical horn antennas designed for 5 GHz unlicensed band. Symmetrical horn antennas solve the biggest issues in the unlicensed bands, the out of R of noise, system loss and network scalability. All you need to assemble and install these antennas is a 5mm Allen key and 30mm wrench. We offer 7 symmetrical horn antennas with beam widths from 30 to 90 degrees and gain from 9.6 to 18.4 dBi. All the following RF features are valid for each one of them. As the name suggests, the radiation pattern of symmetrical horns has the same beam width in azimuth and elevation. There is only one main lobe and zero side lobes, meaning the average beam efficiency across all our symmetrical horns is 93%, which is important for excellent noise rejection. If you want to know more about beam efficiency you can check our short video by clicking the link in the corner or in the video description. The maximum gain is stable over the whole useful bandwidth, so the signal strength is constant regardless of the frequency channel used. Also the rest of the radiation pattern is stable over the whole useful spectrum, providing high coverage stability and reliability, especially for the CPEs at the edges of the sector. The horizontal and vertical radiation patterns are identical, which is yet another addition to the reliability of the symmetrical horn performance on both radio channels. Symmetrical horns feature twistboard, our proprietary wave-god connector that minimizes the RF power loss occurring between a radio and the antenna. Thanks to these favorable properties of symmetrical horns, you can collocate many more sectors compared to the traditional sector antenna technology, saving you money for the tower rental fees and thanks to the lack of side lobes, the neighboring sectors do not interfere with each other and let you get the most out of each access point radio. The performance stability and seven different beam widths and gains of symmetrical horns make them a superb antenna toolset for wireless coverage planning. Anything between dense narrow sectors to wide low density ones is possible. The adjustable down tilt of the horns lets you fine-tune the coverage and noise conditions. Whether it's adopting the coverage or putting up new sectors, there is absolutely no limit to the network scalability with symmetrical horns. It only depends on your need for the overall throughput. Thanks to the extra elevation beam width, symmetrical horns easily cover the null zone at the site. The coverage is reliable regardless of the landscape type, showing their strength, especially in the mountainous regions effortlessly covering the deep valleys. Our symmetrical horns are very robust. They are made of UV-resistant plastic, die cast, stamped and extruded aluminium. They have stainless steel hardware for long lasting durability in all kinds of climates. The main bolts have a black coloured surface coating, protecting them from seizing, extending the durability of the bracket. Symmetrical horns are lightweight, have a wide working temperature range and have a beautiful matte finish. And at the edge of the antenna is a water drain hole, so any condensed water simply leaks out. The installation of symmetrical horns is super easy. But before you start, make sure you know on which side of the pole you will be installing it on. Every symmetrical horn is pre-assembled to be installed on the left side of the pole. If you want to install it on the right side of the pole, flip the position of the bracket so the water drain hole is facing down once the antenna is installed. Also, if the pole diameter is larger than 49mm, flip the bracket for the best result. Once the antenna is up and aimed in the right direction, you can install the radio. It's extremely easy, since twist port lets you do that within a few seconds by a simple twist and lock movement done with one hand. With the twist port interface, the radio is connected and mounted all at once. How cool is that? With symmetrical horns, you can grow smart, reject noise and save spectrum.
