Example of “A” and “B” antennas with antenna cable kit conguraon.
The ClearOne DIALOG 20 Wireless Microphone System is a compact, feature-
rich, and complete 2-Channel Wireless Microphone System built on the 2.4
GHz RF band and ulizing spread spectrum, frequency-hopping technologies
to deliver a simple-to-use, robust, and secure wireless microphone system.
The system consists of a Receiver with two, built-in, passive antennas. When
using a ClearOne Antenna Cable Kit, the antennas can be extended to either
10’ or 25’ lengths in either direcon easily accommodang most conference
requirements and room types. These Plenum-rated antennas adhere to most
municipal re codes, and therefore, they can be extended inside ceiling crawl
spaces for discreet installaon. The available transmiers include: Boundary
tabletop, Gooseneck podium, Handheld and Beltpack.

DIALOG 20 Receivers come with two, Plenum-rated, dipole antennas.
• Mount the antennas on the front of the receiver using a non-conducve
adhesive on the threads of the Female TNC Connector.
• Tilt the antennas slightly outward.
DIALOG 20 Antenna Cable Kits are available in two lengths.
The DIALOG 20 Antenna Cable kit can be used to extend the passive,
Plenum-rated, dipole antennas that are included with the DIALOG 20
Receiver.

open behind hollow wall (Fig. 5; not necessary
for thick or solid walls).
Do not hammer nail or screwdriver.
7Remove the nail or screwdriver.
8Repeat steps 4 - 7 for the second anchor.
To avoid interference, only one anchor should be
installed vercally.

using two (2) wood screws (B) (Fig 6).
Do not overghten screws.
Hollow wall anchors (D) may be used as wedge
anchors in walls thicker than 3/4” or as expan-
sion anchors in solid walls.

Mount antenna over-head and within line of site to
transmiers. The dipole antenna’s recepon is strongest
at the sides of the antenna with a null point at the p.
Therefore, it is best to lt the antenna so that the side faces
the transmiers.
• Wall Mount (Fig. 8).
• Ceiling Mount (Fig. 9, 10, 11).
• Ceiling Mount RX with PoE to CONVERGE® Pro 2
or Beamforming Mic Array 2 (Fig. 11).
• AV Rack Mount (Fig. 12).
Separaon distance of antennas should be a minimum of
2’ (.) and maximum of 30’ (.).

Receiver and secure by using a non-conducve adhesive on the
threads of the Female TNC Connector.
Aach TNC panel mount connector (C) and secure both the
antenna and the extension cable (E) to the antenna extension
bracket (A) by using a non-conducve adhesive on the threads
of both sides of the TNC Panel Mount Connector (Fig. 8).

Professional installaon is required. Installer is responsible for securing antennas with
a non-conducve adhesive and ensuring mounng hardware is appropriate to their
parcular installaon.
