OF84005-FNF is a type of RF antenna which is a specialized device used for transmitting and receiving radio frequency signals in the range of 30 MHz to 450 MHz. They are designed in such a way that they can efficiently transmit and receive signals without causing attenuation and insertion losses. For the purpose of providing excellent communication and networking performance, they are highly directional and powerful.

The antenna is made of a radome, a radiator, and a reflector. The radome is the protective shell that protects the internal antenna parts from dust and other airborne particles. The radiator is the portion responsible for generating and receiving the radio frequency signals by using a dipole element or lattice elements. The reflector, on the other hand, is a section that captures more signals and prevents their reflection toward the desired direction. As such, the reflector enhances the signal transmit power and reception sensitivity.

OF84005-FNF is a low-profile, wideband directional antenna that covers the frequency bands from 30 MHz to 450 MHz. It transmits and receives signals in the vertical and horizontal planes with an excellent radiation pattern and gain of 8.4dBi. Its design features an antenna radiation element that is integrated with an aluminum alloy reflector, thus making it a lightweight and portable antenna for indoor and outdoor applications. Its small size also makes it ideal for use in mobile applications such as portable radios, wireless communication, and Point-to-Point links.

The radio signals that the OF84005-FNF antenna transmits and receives depend on its working principle. The antenna works by using the electromagnetic field created by the oscillations of the electromagnetic waves that it emits. The antenna converts the electrical signals to radio signals, which it then transmits through the air according to the frequency of the oscillations. Upon reaching the other end, the signal is received and converted back into the electrical signals using a receiver.

The OF84005-FNF antenna is versatile and powerful enough to be used in many different fields. It can be used in industrial, military, public safety, and commercial applications. It can also be used for point-to-point communication links, radio broadcast, and in automated applications such as machine-to-machine communication. It is an ideal choice for applications that require directional and wideband coverage of radio frequencies.
