Directional Antennas

The AER550 antenna is…

• 17.5 dBi gain (Max unobstructed range of 1KM)
• Directional
• Parabolic Pole Mount Design Dia 440 x D360mm
• Indirect Connection
• With a 21 deg vertical and horizontal spread

The AER500 antennas have a Female N Type connection so they require a connection cable when used with a product in the VideoMitter range such as the MiniMits.

Wirefree transmission is a superb way to get around difficult on-site issues and adding a pair of antennas to a system can give superb results with “clear line of sight” transmission distances of over 1KM. The Videomitter range of antennas work on frequencies between 2400-2480Mhz and are ideal for use with the wirefree MiniMits video and audio transmitters but can also be used with other compatible devices such as wirefree network equipment.

Antennas are available with direct or indirect connections and in various gains and styles there is a model to suit most installations. Please use our key below to select the right one for your needs. For best results antennas should be bought and fitted in matching pairs with one at each end.

Antenna Gain

Measured in decibels (dBi), the gain of an antenna describes its ability to convert power into radio waves and vice versa depending whether it is used at the transmitting or receiving end of the signal. Depending on the environment, in general the higher the gain the better the performance over long distances.

Antenna’s Directional Ability

Omni: works in all directions and usually in a pole style.

Semi-Directional: often a panel style so easy to fit to a flat wall.

Directional: provides a highly focussed directional signal and tends to be in the satellite dish style known as parabolic and this is more conducive to producing and receiving this type of signal.

Direct or Indirect Connection:

Direct connection antennas are usually smaller in size and connect straight into a socket on your transmitter or other device. They are great for shorter ranges and internal use.

Indirect connection antennas are more flexible but require a lead between the transmitter and the antenna. Although this means the antenna needs mounting independently it offers the flexibility to route the interconnecting lead through the eaves of a building to install the antenna on the outside of the property. In some buildings where metal cladding or foil backed plasterboard can deaden a signal, this can greatly enhance results. This range of antennas have an N socket and leads to connect them to the MiniMits are available in 0.2, 1, 2, 3 and 5m lengths here.
