Stock Room Antenna Placement Issues
When selecting the location of the antennae in the Stock Room, be aware of unique
problems that exist only in the stock room. The problems are caused by the high metal
shelves with inventory stacked to the ceiling, narrow pathways, conduit installed on the
roof girders, roof girders not in the ideal location for the antenna placement, the location of
the inventory, the location of liquids and other issues.
The inventory in the Stock Room is in constant change. Most of the inventory will be on
shelves but many times it will be stacked on the floor or on the conveyor belt. This is an
issue with beverages and other liquids. For example beverages are normally stacked
near the “roll-up” receiving door. But because this is a fast moving item it may not be
there during your installation and you could place Rx-16 over the location where the store
normally keeps beverages and this would prevent Rx-16 from working correctly.
A good rule of thumb on the placement of the antennae in the stock room is to place each
antenna at the locations recommend in this manual, but make sure the antenna location is
centrally located over the natural walking path in that area that is free from potential
obstructions. This minimizes the possibility the store will place inventory under the
antenna and the other natural obstructions that exist in the stock room that would effect
the antennae performance.
Remember never place antennae over shelves (metal or wood), liquids, the trash
compactor and other natural obstructions; it should always be over an open area on the
floor. Never let the antennae or the coaxial cable touch conduit or other cables on the roof
girder. This could damage the antenna.
There are exceptions when Rx-15 and Rx-16 may have to be suspended from the roof
girder to avoid contact with other cables and conduit on the roof girder or if a pipe is
obstructing the line of sight from the antenna to the floor. Never suspend Tx-4 from a roof
girder. It must be mounted to the roof girder.
If you have any questions, concerns or issues with the location of the antennae in the
Stock Room contact the Help Desk immediately.
