3.3.2 Mounting the QTM-24ANT-C
Safety
The QTM-24ANT-C antenna has been designed to attach to and hang from
standard ceiling panel runners. To prevent personal injury or equipment
damage, the antenna must be securely mounted per the following instruc-
tions. The QTM-24ANT-C should be professionally installed.
Location
The location at which the QTM-24ANT-C is mounted is very important.
Objects such as metal columns, walls, etc. will reduce efficiency. Best perfor-
mance is achieved when transmit and receive antennas are mounted at the
same height, and in a direct line of sight with no obstructions. If this is not
possible, and reception is poor, it is a good idea to try a few different mount-
ing positions to optimize reception.
Mounting
The QTM-24ANT-C is suitable for use indoors or outside. The antenna
bracket fits ceiling support runners 13/15” to 1-1/4” (2.1 to 3.2 cm) wide.
To install the antenna, follow the steps below:
(1) Loosen the 1/4-20 hex nut and position the antenna mount over the
support runner. (See Figure 3.3.2.1).
(2) Squeeze the bracket firmly onto the runner (hand-pressure is adequate)
and tighten the hex nut securely as shown in Figure 3.3.2.2
(3) Carefully screw the antenna onto the 1/4-20 screw (lightly hand-
tighten) as shown in Figure 3.3.2.2
(4) Secure coaxial cable along the support runner using tape or cable ties.
If a different mount is used, limit the depth it is threaded into the mounting
hole to .35 inches (.9 cm). For outdoor mounting, install the antenna with the
threaded hole down.
