1. Low-Frequency Antenna: 315mhz/433mhz Wireless Data Transmission/Wireless Monitoring/Wireless Meter Reading Antenna,2. Development And Production Of Communication Equipment Such As Navigation Antennas, Power Splitters/-Arresters, Signal Boosters And Other Devices3. Barrel Antenna 5g Industrial Router Micro-Base Station Antenna4. Installation : This Product Is A Directional Wall-Mounted Antenna With Strong Signal Reception And Strong Directivity. The Higher The Gain, The More Signals Are Gathered, And The Higher The Angle Requirements Are. However, This Antenna Radiates Directional Antenna Rather Than Omnidirectional Antenna Radiation. The Antenna Needs To Adjust The Position And Direction Of The Antenna'S Reception (Transmission) To Achieve Better Results.5. Directional Antenna Usage Environment: It Is Best Not To Be Blocked By Objects Between The Directional Antenna Signal And The Receiver. The Fewer Obstacles, The Better. Align The Antenna With The Signal Source. The Higher The Receiving Location, The Better, And The Climate Must Not Have Tides.
