Anli A-300 MU-Nantenna is a basic all-directional UHF antenna with a circular radiation pattern (DN), with high gain comparable to the gain of directional antennas.
The Anli A-300 MU-N base antenna consists of 6 collinear radiating elements interconnected by phase-shifting chokes that compensate for a negative phase shift of 135 degrees (3/8") and they practically do not emit themselves. Due to this, all six elements are powered in series and emit in-phase. By adding up their capacities, the bottom narrows in the vertical plane, while the maximum bottom is perpendicular to the antenna axis.
The antenna body is made of cross-wound three-layer fiberglass and is highly resistant to high wind loads. The antenna is supplied tuned to the range of 400-420 MHz, the adjustment to other ranges is carried out according to the instructions by shortening the emitting elements.
The antenna is powered by a grounded autotransformer. UHF band antennas are supplied with an N connector (socket). The A-300MU-N stationary antenna has been successfully used in the CIS market since 1997.
Advantages of the basic antenna Anli A-300 MU-N:
- High gain.
- The best price/quality ratio.
- Low weight and high wind load.
- Low SWR value in a wide UHF frequency range (400-512 MHz).
- The antenna is convenient for installation on building facades and pipe walls.
- Easy installation and configuration. <lt;li>High quality of execution. The antenna has an extended service life.
A properly assembled Anli A-300 MU-N antenna has the specified parameters and does not require additional configuration. The antenna is connected to the equipment using a feeder of the required length. Laying the feeder along the mast, entering the building and connecting to the equipment must be carried out taking into account lightning protection standards using earthing devices and lightning dischargers. The product does not require any special maintenance. During the operation of the antenna, at least once every six months, it is necessary to visually inspect the condition of the antenna mounts, the fiberglass housing, the feeder and the v/h connectors. In case of mechanical damage, it is necessary to take measures to eliminate them.
Antenna Installation Anli A-300 MU-N:
Nearby objects such as trees, power lines, other antennas, etc. can significantly impair the operation of the product. The antenna is mounted on a mast with a diameter of 30-70 mm and should be installed as high as possible and as far away from surrounding objects as possible. When installed on a building, the antenna must be positioned at least 1/4 wavelength (/4) away from the building wall.
