When it comes to choosing antennas for meeting room full-screen segment signal jammers, there are two options available: directional antennas and omnidirectional antennas. To determine which type is suitable, it’s important to understand the characteristics of each.
Omnidirectional antennas, as the name implies, radiate signals in all directions on the horizontal plane. They are easy to assemble and do not require precise technical considerations regarding installation angles. These antennas are commonly used in full-screen segment signal jammers when the device is positioned close to the ground and needs to cover a large area. They are cost-effective and typically have a gain value below 9dB. The coverage pattern of an omnidirectional antenna resembles the outline of an apple.
On the other hand, directional antennas are used in full-screen segment signal jammers when the objective is to shield a specific area with a long signal transmission distance, a small coverage area, and a high density of targets. These antennas have a focused coverage area that resembles a cone or a sound horn shape. In comparison to omnidirectional antennas, directional antennas provide a stronger signal in a particular direction. They have a bowl-shaped front surface that transmits signals, while the rear surface blocks and reflects signals, enhancing the strength of the transmitted signal in the front.
In the context of conference rooms, full-screen segment signal jammers are typically installed in the front, rear, left, and right sections of the room, strategically positioned for maximum effectiveness. Therefore, when utilizing a full-screen segment cell phone signal jammer in a conference room, a directional antenna can be employed to concentrate interference in the frontal direction, thereby increasing the distance over which interference occurs.
