FM transmitter antennas we made include dipole antenna, dual-dipole antenna, 2-layers dipole antenna, 2 layers dual-dipole antenna and vehicle-mounted antenna. In most case, FM antenna is installed at the top of iron tower in 10 to 300m height. The wind at this height is very strong. As a result, the mechanical vibration of antenna is usually very frequently, whick make it suffers from metal fatigue. The temperature difference, snow, humidity and even the acid snow are also a big problem which will affect the performance and service life of antenna. The installed height of antenna makes the regular maintenance quite difficult. All above reasons highlight the importance of choosing a quality guaranteed FM radio station antenna.
All Allink’s FM and TV broadcast antennas adopt first class stainless steel made by Baosteel group. The good material makes the antenna very durable. It has an outstanding anti-corrosion and anti-fatigue performance.
To choose a right antenna for broadcasting system, many factors need to be taken into consideration. The programme bandwidth, output power of transmitter, height of tower, transmitting coverage area and polarization are the priority factors to be considered. To make the choice of antenna easier, we have a recommendation table introduced how to choose transmitter and antenna based on coverage range in FAQ.
In some cases, one radio station need to broadcast several channels.The bandwidth of one channel is relatively narrow, while the bandwidth of antenna is wide. Therefore, we can use multiplexer to connect one antenna with multi transmitters. It is a rather reasonable way to share the antenna, which will save the whole cost.
