How can I buy a cheap FM radio station antenna?
FM radio antenna is one of the most important and expensive transmission equipment for FM radio stations. If you can choose a durable and good performance FM radio antenna, you can save a lot of time and effort and maintenance costs, RS-RADIO brings you FM radio antenna deals.
This is very important, especially for RF beginners. However, they need a buying guide to help them filter out the most important buying information about FM broadcast transmitting antennas.
Luckily, we're going to give you six of the most important buying tips to help you get the best deal on an FM radio station antenna. Let's get started!
Type of FM broadcast
You need to choose the best FM broadcast antenna type with different characteristics for different applications. Generally speaking, there are several common types of FM broadcast transmitting antennas:
Monopole FM antenna - It is best for narrow ranges and can be folded. It is commonly used in low power FM radio transmitters and vehicles.
Dipole FM antenna - It is one of the most commonly used types of FM radio station antenna. It has a wide frequency band and can radiate in all directions.
Yagi FM antenna - Yagi antenna is a high gain antenna. It is ideal for applications that require long distance one-way radio signal transmission, such as Studio Transmitter Link that requires long distance transmission.
Circularly polarized antenna - It allows both vertical and horizontally polarized receiving antennas to receive radio signals.
FM broadcast directionality
Of course, directionality is important. You need to know the purpose of your FM radio station.
If you want to transmit your radio broadcast to a nearby audience, then you may need an omnidirectional antenna, such as a dipole FM antenna, or a combination of several directional FM broadcast antennas.
And if your FM station is designed to transmit radio signals in one direction, as Studio Transmitter Link is, then you undoubtedly need a directional FM radio antenna, such as an Yagi FM antenna.
Higher gain means that your FM broadcast antenna concentrates the radio signal in a more limited space, resulting in stronger radio signal strength. This also means that gain and directivity are related, and increasing gain may sacrifice a certain range of radiation.
There are many ways to improve the gain, such as increasing the number of FM radio antennas or switching to FM broadcast antennas with higher gain. This depends on the characteristics of the radio broadcast signal you need.
Bandwidth is important!!
In terms of bandwidth, there are two types of antennas: broadband FM antennas and tuned FM antennas.
Wideband FM antennas have a fixed bandwidth of about 20MHz and can operate properly in all 20MHz of the FM band. And it works well in bandwidth.
Tuned FM antennas are only suitable for small bands near their tuned frequency. And it can't maintain the same performance in 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 antenna, which is divided into vertical polarization and horizontal polarization. The polarization direction of the receiving antenna and the transmitting antenna should be matched to obtain good communication effect. Therefore, the choice of polarization mode depends on the local situation.
If you're not sure which polarization is better, you can choose a circularly polarized antenna, which has both vertical and horizontal polarization, but the receiving antenna's reception efficiency is halved because the radio signal power is evenly divided in both directions.
Good FM radio manufacturer
The best brands can guarantee the high quality of their products, such as FMUSER. Not only that, but you can also get their excellent services and products at the most reasonable prices, reducing your procurement costs and making you more focused on the work of FM station operations.
Let's summarize how to choose the best FM radio antenna:
Type: Select different FM broadcast antenna types based on application scenarios
Directionality - depends on the purpose of the signal transmission.
Gain - This depends on the characteristics of the radio signal you want.
Bandwidth - The wider the better, as many FM signals as possible.
Polarization - Make sure the radio can receive your broadcast well.
Based on these 6 purchasing tips, even if you are an RF beginner, you can find the best FM radio antenna and improve the radio signal to its best condition.
