225MHz-400MHz Weather-Resistant Wideband Log-Periodic Antenna

The Model ZD2254 225MHz-400MHz log-periodic antenna developed by ZDTECH is a professional communication antenna with stable performance and adaptability to multiple scenarios. Its frequency coverage range is accurately positioned from 225MHz to 400MHz, with a gain of more than 6dBi; the maximum gain can reach 7.6dBi to 8.8dBi at different operating frequencies. The 3dB beam width ranges from 60° to 125°, and the E-plane and H-plane 3dB beam widths show precise adaptation characteristics with frequency changes. For example, at 225MHz, the E-plane 3dB beam width is 67° and the H-plane is 111°, while at 400MHz, the E-plane is 60° and the H-plane is 89°, enabling efficient coverage of the target signal area.

The antenna is made of high-durability Alufer material, with an army green coating on the surface, which not only has good structural strength but also can adapt to complex environments. Its overall dimensions are 1270mm×770mm×146mm, and it achieves stable installation through an installation panel, compatible with N/L29 type connectors to meet the connection needs of different devices. In terms of performance parameters, its typical standing wave ratio is 1.5, the maximum power capacity reaches 100W/800W, the operating temperature range is -55℃ to +75℃, and the storage temperature range is extended to -65℃ to +85℃. Even in extreme environments such as low temperature and high temperature, it can maintain stable communication, making it suitable for scenarios with high requirements on antenna reliability and weather resistance.
