EXC400BN

One of the primary components of an RF communication system is an antenna, and the EXC400BN is a type of radio-frequency antenna. Specifically, it belongs to the unidirectional type antennas, which can be used in a variety of communication systems and applications. This article presents the applications and working principles of the EXC400BN radio-frequency antenna.

Applications

The EXC400BN is a highly versatile antenna that can be used in a variety of applications. It is most commonly used in applications where high-gain directional communication is needed. Typically, these include point-to-point or point-to-multipoint communication applications, such as Wi-Fi, cellular networks, ATV, WIMAX and satellite communication systems. It can also be used for short-range applications, such as two-way radio communication or amateur radio. The EXC400BN’s rugged construction and weatherproofing allow it to perform reliably in various environments.

Working Principle

The EXC400BN employs a two-dipole directional antenna design, which uses two radiating dipole elements. These elements are oriented in a colinear manner, and the antenna is mounted approximately two-thirds of the way up a support tower. The antenna’s beamwidth is typically 10 to 15 degrees, and the gain can reach up to 10 dBi. This allows the EXC400BN to operate at a distance of up to 2 km with 40 Watt of transmit power, or 4 km with 20 Watt of transmit power.

The antenna’s gain is the result of superposition of the radiated fields produced by the two dipole elements. These two elements are electrically separated, and the angled orientation creates an electrical phase shift between them. This shift amplifies the gain of the antenna and causes it to be more directional. The antenna also utilizes a simple low-loss feed line to connect the antenna with the transmitter or receiver, which improves the efficiency of the transmission system.

The EXC400BN is a reliable and cost-effective antenna that is capable of providing high-gain, directional transmissions in a variety of applications. It is a great choice for any radio-frequency communication systems, and its rugged construction and weatherproofing make it suitable for use in a variety of harsh environmental conditions.
