for 25 feet, 15 dB for 50 feet, and 26 dB for 100 feet. Once connected and with the receiver on, conﬁrm

that the blue light on the front of the antenna is lit. Walk-test the area after the antennas are placed to

make sure that it is properly covered without interference or dropouts.

Note, As the RF signal travels through the cable to the antenna distribution system, there will be some

loss of signal level, which at greater lengths and with higher loss cables can be signiﬁcant. With an

active antenna that provides additional gain, set it to the proper ampliﬁcation for the cable length, and

try not to exceed 100 feet (30 meters) of cable.

Omnidirectional antennas are best applied when the users will be transmitting from a wider area – in

front, to the sides, and even behind the antenna. Directional antennas provide greater signal strength

at the front of the antenna, and greater rejection of the signal at the rear – in the case of the P180,

a cardioid coverage pattern of approximately 90 degrees with a rolloff to the sides. Use them when

the users are in a more conﬁned area or not roaming as much. They can also be used to minimize an

interfering signal source by facing the back of the antenna toward the interferer and the front toward

the transmitters.

Problem Solution

Little or No Antenna

Signal at Receiver

XD-AD8 not turned on.

Antennas not connected to XD-AD8.

Antenna cable is too long, incorrect impedance, defective or is not a low-loss type.

Gain setting on remote antenna set at improper level.

ANTENNA SELECT switch not set to connected antennas.

BNC-to-BNC cables not attached between XD-AD8 and receivers, or loose

connection.

Connections between XD-AD8 and receivers mixed up; make sure each receiver has a

connection from the antenna A and antenna B block.

Antennas not in line-of-sight with receivers, or at too great a distance.

Incorrect channel settings between transmitters and receivers.

Receivers Not Being

XD-AD8 not turned on.

Power distribution cable not plugged in or loose.

Receiver power switch not turned on.

Range or Interference

Issues

Move antennas away from potential interfering sources such as WiFi routers, computers,

and other 2.4 GHz equipment.

Move the antennas closer to the location where the transmitters are being used, or raise

so that they are in line-of-sight
