Guide To Select The Right Antenna Mast
March 12,2022
As we know that antenna mast has different types and sizes, such as manual, hydraulic and mechanical antenna mast and 10ft, 30ft, and 40ft antenna mast. So, do you know what need to considerate when choosing the mast?
What Is Antenna Mast?
Antenna mast, often referred to simply as antenna or aerial, is used to receive television signals. It can also be used to receive radio signals, including traditional broadcast stations and amateur or "ham" radio. Since the service life of antenna masts is usually quite long, it is worth taking time to select a quality mast that fits your needs.
Types Of Antenna
According to the nature of the work can be divided into transmitting antenna and receiving antenna.
It can be divided into communication antenna, broadcast antenna, television antenna, radar antenna, etc according to the function.
According to the direction can be divided into omnidirectional antenna and directional antenna.
According to the working wavelength, it can be divided into ultra-long wave antenna, long wave antenna, medium wave antenna, short wave antenna, ultra-short wave antenna, microwave antenna, etc.
According to the structure and working principle, it can be divided into line antenna and plane antenna. The characteristic parameters describing the antenna are the pattern, directivity coefficient, gain, input impedance, radiation efficiency, polarization, and bandwidth.
According to the dimension, it can be divided into two types: one-dimensional antenna and two-dimensional antenna
- One-dimensional antennas: Made up of many wires, either straight lines like those used on cell phones or neat shapes like the old rabbit ears used on television before cables. Monopole and bipolar antennas are the two most basic one-dimensional antennas.
- Two-dimensional antennae: vary from sheet (a square piece of metal), array (a bundle of well-organized two-dimensional patterns), trumpet, dish.
Antennas can be divided into three categories according to the different occasions: handheld antenna, vehicle-mounted antenna and base antenna.
- Hand-held station antenna: is the personal use of hand-held walkie-talkie antenna, common rubber antenna and pull rod antenna two categories.
- Vehicle antenna: refers to the original design of communication antenna installed on the vehicle, the most common application is the most common suction cup antenna. The vehicle antenna structure also has shortened type, quarter wavelength, middle inductance type, eighth-fifth wavelength, double half wavelength antennas and other forms.
- Base station antenna: it plays a very key role in the whole communication system, especially the communication station as the communication hub. The common base station antennas are FRP high-gain antenna, four-ring array antenna (eight-ring array antenna) and directional antenna.
How To Choose Antenna Mast?
One of the most important variables to examine an antenna mast is its gain. This is a number in decibels that measures the sensitivity of the mast and its ability to receive broadcasts. The further away you are from the nearest broadcast tower, the greater the gain you need. In many cases, the gain increases with the physical size of the mast, but this is not a hard and fast rule.
Another variable is directionality or power density. The more directional the mast is, the better it performs where there is a building or hill between the mast and the broadcast tower. One measure of directionality is the Angle of reception: the narrower the better. Another measure is the before and after ratio. The higher the value, the more the mast can receive signals from the right direction without interference from other directions.
Last but not the least, the antenna quality is also a factor to influence the use of antenna mast. Even a good antenna mast will produce poor results if you use a low quality antenna.
In Conclusion
The gain, power density and the quality of antennas are three factors you need to take into consideration when you choose antenna mast. By the way, WESILI has 10ft, 30ft, and 40ft antenna mast for wholesale if you want to buy 10ft antenna mast.
