Fmuser DP100 Exclusive Half Wave FM Dipole Antenna High gain outdoor Dipole antenna 88 to 108mhz for FM Transmitter up to 150w. Frequency range : 88108 MHz (1MHz stepping).

Input Impedance Impedance : 50 ohm. Horizontal 3dB Beam Width : 360 ° Vertical 3dB Beam Width : 73 °. Height: 990mm Radiating Element Material:Aluminum Alloy.

Connect antenna first, then connect the power supply, otherwise, transmitter will be burned out. When setting the antenna, the "Sky" end should be face up, "Ground" should be face down. This package contains an 8 meter coaxial feeder cable, we will send cable with BNC connector. If you have special requirements, please contact customer service.

1 High quality 8 meter coxial cable with BNC interface. What it is 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. 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.

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