Electric Sleeve Dipole Antenna

The electric sleeve dipole antenna adopts a symmetrical vibrator design, the directional pattern is symmetrical in azimuth, and a single-section or multi-section choke coil design is used to reduce the influence of the coupling current on the surface of the cable on the pattern.

The antenna covers the frequency range 0.3-6G, the standing wave performance is good, and the gain is flat. It has good electromagnetic performance, low loss and high efficiency, low cross polarization, azimuth plane symmetry within ± 0.1dB, conforming to CTIA standard. Good mechanical properties, light and firm. The meticulous structural design, the clamp position of uniform size, the consistent distance between the antenna phase center and the connector, are easy to install.
