5 Common Aerial Types
In order to receive images as well as data, it is necessary to invest in a good antennae or aerial. The aerial type that you install will greatly influence the picture quality, sound clarity, and also transmission of data. Since inception, many types of aerials have found their way into the market. In fact, more-and-more are being discovered as the days go by. The following are some of the most common types:
1. Yagi Aerial
This is considered as the standard type of antennae and is quite common. The aerial consists of a number of spiky elements that range from 10 to 18 in number. They are connected to a rod that is also attached to a reflector. It is a directional type of aerial meaning that it picks the signal by facing the direction of the source. A type that has more or longer spikes will have better reception.
2. Digital High Gain Aerial
This is a more advanced form of the yagi type of aerial. It features many spiky elements with some digital models having as many as 100 elements. The aerial may also come with two reflectors instead of one. Due to its design the aerial is mainly used in regions that have weak signal, or when high quality imagery or reception is required. Digital High Gain can receive either selected frequencies or wideband.
3. Grid Aerial
Grid aerials are also quite common. They feature a sort of mesh that captures the frequencies or signals. Usually, it is used for analogue reception where very high resolution or picture clarity is not really needed. Unfortunately, it is not suitable for Freeview reception. The aerial type is most suitable in areas that have strong signal receptions. For better reception people replace the Grid aerial with a high gain Yagi antennae that is suited for digital reception.
4. Indoor Aerial
Indoor aerials come in smaller sizes compared to the outdoor antennas. They are mainly mounted on the device, next to it or nearby. The aerial is effective in areas where the signal strength is strong. This includes; high-rise buildings, areas near the transmitter, or where there are no obstacles along the signal path. Indoor aerials do not generally offer good Free-view receptions. In order to improve the signal reception the aerial can be connected to a boaster.
5. Loft Mounted Aerial
Loft mounted aerial is also another form of outdoor antennae. It is mainly used to receive analogue signal and is mounted on the roof. The aerial doesn’t offer very reliable Free-view reception because the plumbing or roof tiles may interfere ith the signal quality. To avoid the loss or weakening of the signal a satellite-grade cable is used to connect the antennae to the device.
Having the best quality aerial doesn’t necessarily mean you will have the best reception. Your television, camera, radio or any other related accessory will work best if the right type is used. When installing an aerial or antennae it is vital to consider a number of factors. First, it should be placed at the right location. Second, it should be suitable for the device in hand. Third, the aerial type should meet the industry requirements.
