2.4. FLEXBEAMER® Installation Instructions
2.4.1. General Array Installation Instructions
We recommend using a 3”-4.5” diameter pole for the FLEXBEAMER® System installation. The
figures later in this section illustrate the installed FLEXBEAMER® units, showing the Tx and Rx
cables connections.
The RF coaxial cables connecting the BAU FLEXBEAMER® and the RAC can be of any 3/8” or ½”
diameter low loss type. These cables carry DC Current and RF signals from the RAC to the BAU and
FLEXBEAMER®. Since the FLEXBEAMER® include the Power amplifier and the LNA, the losses
on these cables can be high without affecting the overall performance. Thus , these cables can be as long
as 100 meters .
Sealing and weatherproofing of RF connector is of prime importance to assure good electrical contact
for many years, minimizing DC loss and passive RF inter-modulation effects. Thus, special care should
be taken with the RF connectors sealing and weatherproofing especially at the FLEXBEAMER® input
connectors that are exposed to extreme environmental conditions. Common sealing practice should be
used.
For sealing instructions, refer, for example, to Andrews weatherproofing recommendations with 3M
TM
Cold Shrink
TM
Weatherproofing Kit, or an equivalent sealing method.
Before installing the FLEXBEAMER® unit, note that each FLEXBEAMER® and BAU has a Tag
attached to it. After installation remove the tag keep it and log this info in the system manual book. This
tag carries the BEAMER
®
modules address.(This address is the serial number of each BEAMER
®
unit as appears on the module label nearby the Rx connector).You will need these IDs later, for system
configuration setup.
2.4.2. Unpacking
Unpack the units and verify that there are no mechanical damages to any of the parts of the
FLEXBEAMER® units.
