always be possible for a number of reasons. First, interference or propagation
problems may mean that not all antenna slots are available all the time. Second,
a beltpack constantly searches for the best antenna signal, and may frequently
switch antennas. To make this transmission seamless, a beltpack maintains the
connection to its current antenna until it is confident that the new antenna is
functioning well. Therefore, for a short period of time during this transition, a
single beltpack can occupy slots on more than one antenna.
This means that for zones likely to need coverage for up to five or more beltpacks
simultaneously it is recommended that a second antenna is installed. Similarly,
for good coverage for nine or more beltpacks simultaneously, a third antenna may
be required. See Figure 2-3 Antenna/beltpack capacity.
3.4.5 Conditions affecting coverage areas
The environment in which a system is located affects the coverage area for any
particular beltpack/antenna combination. The presence of walls, floors, ceilings,
trees, shrubbery, people, and numerous other items may affect the coverage
zone. Metallic objects, safety doors, lighting equipment, and bodies of water may
possibly block transmission. Also, the presence of other control systems in the
area. These factors must be taken into consideration when planning the
installation.
See 2.1.3 Using multiple Base stations in the same radio frequency (RF) space for
more information on multiple Base station systems.
3.4.6 Surveying a site in standalone (rigging) mode
You might need to scope a site (check the range and performance of an antenna)
without connecting to a Base station. To do this, a beltpack and antenna can be
put into standalone or rigging mode.
To put a beltpack and antenna into standalone mode:
Make sure you have to hand:
A beltpack
A transceiver/antenna
A DC in XLR (male) power connector for the antenna.
Access to a power socket.
8) Connect the power to the transceiver/antenna and at the same time
press the black mode button on the base of the antenna.
This puts the antenna in standalone mode, and opens it for pairing to a
beltpack.
