Screw External Flach Dach High Gain 4g Puck Antenna With Door Loop Cable

Outdoor PUCK 4G LTE Screw External Flach Antennen Dach Antenna With Door Loop Cable

Antenna installation For outdoor antennas, lightning protection equipment needs to be added between the antenna and the wireless AP; for directional antennas, pay attention to the direction that the front of the antenna faces the remote site; the antenna should be installed as high as possible, between the antenna and the site as much as possible Meet the visual distance (visible to the naked eye, avoid obstacles in the middle).

Electrical Characteristics:

The connection between the antenna and the feeder is called the input or feed point of the antenna. For wire antennas, the ratio of the voltage to the current at the input of the antenna is called the input impedance of the antenna. Regarding mouth-type antennas, the voltage standing wave ratio on the feeder is often used to indicate the impedance characteristics of the antenna. Generally, the input impedance of an antenna is a complex number, the real part is called the input resistance, which is indicated by Ri; the imaginary part is called the input reactance, which is indicated by Xi. The input power Pi of the antenna can be marked as where |Ii| is the peak current at the input of the antenna; R is the radiation resistance with the input current as the reference, where Pr is the radiated power of the antenna; R0 is the ohm with the input current as the reference A section of the loss resistor carries a uniform current and the length l is much smaller than the working wavelength λ of the ambition dipole antenna called the current element.

Its radiation resistance Rr is very small, and the input reactance of the antenna represents the power stored in the near field of the antenna. The antenna whose electrical specification is much smaller than the operating wavelength has a large input reactance. For example, a short dipole antenna has a large capacitive reactance; an electric small loop antenna has a large inductive reactance. The input impedance of the half-wave oscillator with a very small diameter is about 73.1+j42.5 ohms. In practice, in order to facilitate matching, it is generally hoped that the input reactance of the symmetrical vibrator is zero, and the length of the vibrator at this time is called the resonance length. The length of the resonant half-wave oscillator is slightly shorter than the half-wavelength in free space, and it is generally estimated to be shortened by 5% in engineering. The input impedance of the resonant half-wave oscillator is about 70 ohms.
