The fixed Model 90 antenna is optimized for the UHF 470 to 862 MHz frequency band. Its nominal gain is 8 to 12 dBi with a circular omnidirectional radiation pattern. Standard input impedance is 50 ohms with an N-Female connection port. Voltage Standing Wave Ratio VSWR is guaranteed below 1.5 across the entire operating band. The main structure consists of a fiberglass rod reinforced with a UV-resistant polyurethane coating. Total antenna height is 120 cm with a reflector diameter of 45 cm. Resonant elements are made from 6061 alloy aluminum with an epoxy coating. This antenna can receive DVB-T/T2 digital signals with a minimum signal level of -95 dBm. It withstands wind speeds up to 150 km/h. The operational temperature range is -40 to +85 degrees Celsius.
The antenna structure comprises an 8-element vertical collinear array design. Central feed is accomplished with an integrated 1:1 balun to reduce common-mode noise. A circular aluminum ground plane with a 60 cm diameter focuses the waves. The mounting base is made of 3 mm thick hot-dip galvanized steel for strength. Connectors are waterproof with an IP67 rating for outdoor environments. The antenna operates without an active Low-Noise Amplifier LNA. This design eliminates power consumption and increases reliability. Installed antenna weight is 4.2 kg. It is suitable for fixed installation on masts, rooftops, or walls at a 90-degree angle. The default included cable is a 2-meter low-loss RG-213 coaxial cable.You can order and buy Fix 90 Antenna from Iran by contacting us through whatsaap and email.

Installing and Adjusting a Fixed Antenna
Installing a fixed antenna requires adherence to safety principles and technical precision. First, select an unobstructed installation site with a direct line of sight to the transmission tower. The antenna mount must be securely fixed to a stable wall or roof using appropriate screws and wall plugs. Mount the antenna reflector on the base and secure it with dedicated clamps. Connect quality coaxial cable RG6 from the antenna to the TV input and use a waterproof drip loop at the antenna connection. Align the antenna direction precisely towards the tower using a compass and tighten it with a suitable wrench. After connection, run the Digital TV Auto Scan menu on your TV. If reception is poor, optimize the antennas angle and height using a local broadcast map. Perform a signal strength test via the TV menu. Checking connections, insulation, and lightning arrestors is essential for safety and longevity. For areas with very weak signals, using a high-gain antenna and a powerful amplifier is recommended.
