1. What it is a dipole antenna ?

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.

2. 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 from88~108 by 1mhzstepping.

2).The dipole is a simple antenna to construct and use, and many of the calculations are quite straight forward.

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).
