Avocent manual Emerge HGA51G-DIR30Directional Antenna, Additional Information

The following will help you install your directional antenna easily. Should you require further assistance, please contact Avocent Technical Support.

Additional Information

Emerge extenders feature an intelligent dual antenna system, in which the antenna with the strongest receive signal becomes the active antenna for transmission while the other becomes passive. For this reason the directional antenna, due to its increased sensitivity, will become the active transmission antenna when environmental conditions are static. Under such conditions there is no reason to install multiple directional antennas on a single device. Transient environmental conditions, however, as might occur in a warehouse in which boxes are routinely stacked and moved, can impair the signal of the active antenna, resulting in activation of the passive antenna. Under these shifting conditions, it might be advantageous to install two directional antennas on a single Emerge

Emerge HGA51G-DIR30 directional antennas are compatible with each other as well as with omni-directional antennas. It is recommended to install at least one directional antenna on both the transmitter and receiver because the receiver’s acknowledgements must be properly received by the transmitter.

The directional antenna achieves extended range by concentrating its radiated power in a narrow (approximately 30 degree) arc. Therefore, care must be taken to ensure that all receivers paired with a transmitter are located within the 30 degree arc of its directional antenna.

Because a directional signal is focused into a relatively narrow arc, it is easily blocked by

objects such as steel beams, HVAC ducts and re-bar. For this reason, care must be taken to avoid obstructions in the signal path. Moving the transmitter or receiver a few feet may improve performance significantly.

The HGA51G-DIR30 antenna is designed to provide 8 dB of gain within the 5.150 – 5.825 GHz UNII bands.
