A dipole antenna is a radio antenna that can be made of aluminum, copper, and bronze tube with a center-fed driven element. It consists of two metal conductors of rod, oriented parallel and collinear with each other (in line with each other), with a small space between them.

The dipole antenna is a particularly important form of RF antenna which is very widely used for radio transmitting and receiving applications. The dipole is often used on its own as an RF antenna, but it also forms the essential element in many other types of RF antenna. As such it is the possibly the most important form of RF antenna.

A half-wave dipole antenna means the length of this dipole antenna is equal to a half-wavelength at the frequency of operation.

Why do we recommend this dipole antenna?

1).The half-wave dipole is very clear and easy for frequency adjustation, there are scales on the side bar of the antenna from which you can adjust the frequency from 88~108 by 1 MHz stepping. 2).The dipole is a simple antenna to construct and use, and many of the calculations are quite straightforward.
3.) The radiation pattern and high gain of dipole:
Radiation pattern of a half-wave dipole antenna, scale is linear.

The Gain of a half-wave dipole (same as above). The scale is in dBi (decibels over isotropic).

The cable supports:
The frequency 0-12G
Note: 1/2 what does it mean?
Is the outer diameter of the metallic shield of the feeder units of inches, regardless of the inner core and coaxial .1 / 2 refers to the outer diameter of the metal shield is 1.27 cm feeder 7/8 refers to the feeder outer diameter of the metallic shield is 2.22 cm, the outer insulation is not including.

Depending on the wireless transmission of electromagnetic waves in the frequency in the feeder, the attenuation of the signal intensity is different. For example: the electromagnetic frequency: 890 — 920M, attenuation at 1/2 feeder is: 7.5 – 7 .7dB/100 meters. 7/8 feeder attenuation of approximately: 4.2 – 4 .5/100 meters.
