If the transmitter is to be wall-mounted, 

allow sufficient clearance for the curved 
antenna face to swivel freely in all directions.

 

Repeat steps 2 through 5 for the receiver. 

For best results, position the wireless extenders 
so they are on the same horizontal plane.

 

Using the signal strength LEDs for 

guidance, swivel the curved face of transmitter 
antenna head toward the directional antenna on 
the receiver.

The HGA51G-DIR30 directional antenna is 
an accessory for Emerge wireless extenders, 
which are factory-equipped with omni-
directional antennas. Directional antennas 
provide extended range operation by focusing 
the energy of radio waves into an intensified 
directional beam. Extended distance operation 
requires installation of at least one directional 
antenna onto a transmitter and one onto a 
receiver. Installation of two antennas per unit 
will guard against signal blockage but will not 
increase transmission distance.

 If your wireless extenders are not already 
properly placed and connected to audio, video, 
power and control sources, then please refer 
the appropriate product documentation before 
proceeding with the instructions provided in 
this document.

 Facing the product, remove the omni-

directional antenna from the left-hand antenna 
jack on both the transmitter and receiver. 
The antennas loosen from the antenna jack 
by turning the knurled fastener in a counter-
clockwise manner.

 

Select either directional antenna and 

extend the assembly such that its connector 

arm and antenna shaft are parallel with each other at 
the knuckle joint.

 

Engage the center socket of the antenna 

connector arm onto the center pin of the transmitter 
antenna jack. Turn the knurled fastener clockwise 
until finger tight to secure the antenna.

 

If the transmitter is to be shelf or rack mounted, 

raise the antenna head such that the antenna 
shaft is pointed upward and perpendicular to the 
connector arm at the knuckle joint. This motion 
requires proper alignment of the knuckle joint, 
which can be accomplished by rotating the antenna 
shaft. Once vertical, swivel the curved antenna face 
toward the intended receiver.
