6 Sparekostnader Tips for å kjøpe en FM-radiostasjonsantenne
FM radio station antenna is one of the most important and expensive transmission equipment for your FM radio station. It can save you a lot of time and effort and maintenance costs if you can choose a durable FM broadcast antenna with good performance.
It is very important, especially for RF beginners. However, they need a buying guide to help them filter out the most important buying information about the FM broadcast transmitter antenna.
Fortunately, we will provide you with the 6 most important buying tips to notice, to help you buy the FM radio station antenna at the best prices. Let's get started!
You need to choose the best type of FM broadcast antennas with different characteristics based on different applications. Generally speaking, FM broadcast transmitter antennas come in the following common types:
Monopole FM antenna - It works best for narrow ranges and can be collapsable. It is usually used in low power FM radio transmitters and vehicles.
Dipole FM antenna - It is one of the most popular types used in FM radio station antennas. It has a wide frequency band and it can radiate in all directions.
Yagi FM antenna - The Yagi antenna is a type of high gain antenna. It is ideal for applications that require long-range one-way radio signals transmission, such as Studio Transmitter Link which needs to transmit for a long way.
Sirkulært polarisert antenne - It allows both vertically and horizontally polarized receiving antennas to be able to receive radio signals.
Of course, directionality is very important. You need to be clear about the purpose of your FM radio station.
If you want to transmit your radio broadcasting programs to the surrounding audience, then you probably need an omnidirectional antenna, such as a dipole FM antenna, or a combination of several directional FM broadcast antennas together.
And if your FM radio station is used to transmit radio signals in one direction like Studio Transmitter Link, then there is no doubt that you need a directional FM radio station antenna, such as a Yagi FM antenna.
Higher gain means that your FM broadcast antenna concentrates the radio signal in a more limited space, which leads to the stronger radio signal strength. It also means that the gain and directionality are related, and increasing gain may sacrifice a certain range of radiation.
There are many ways to improve gain, such as increasing the number of FM radio station antennas or replacing them with the FM broadcast antennas with higher gain. It depends on the characteristics of the radio broadcast signals you need.
In terms of bandwidth, there are two types of antennas: wide band FM antenna and tuned FM antenna.
The wide band FM antennas have a fixed bandwidth of about 20MHz and work well in all 20MHz of the FM band. And it can work well in the bandwidth.
Tuned FM antennas are adapted only in a small band around the frequency to which it was tuned. And it can't work retaining the same performance in the bandwidth.
Broadband FM antennas are always preferable to tuned ones even if they cost more.
Polarization refers to the direction of the electromagnetic field generated by the FM radio station antenna, and it is divided into vertical and horizontal polarization. The polarization direction of the receiving antenna and the transmitting antenna should be matched in order to have a good communication effect. Therefore, the choice of polarization depends on the local situation.
If you are not sure which polarization is the better choice, you can choose a circularly polarized antenna, which has both vertical polarization and horizontal polarization, but the reception effect with the receiving antenna will be halved, because the radio signal power will be divided equally in two directions.
The best brand can guarantee the high quality of their products, such as FMUSER, and not only that, you can also get their quality services and products at the most reasonable price, reducing your purchase and other costs and allowing you to focus more on the FM radio station operation work.
Let's summarize how to choose the best FM radio station antenna:
Typer - Choose different FM broadcast transmitter antenna types according to the application scenario
retnings - It depends on the purpose of signal transmission.
Gevinst - It depends on the radio signals characteristics you want.
Båndbredde - The wider the better, as much as possible for the FM signal.
Polarisering - Make sure that the radios can receive your broadcasting programs well.
Based on these 6 buying tips, even if you are an RF beginner, you can find the best FM radio station antenna, and improve the radio station signals to the best.
