Antenna Installation Requirements
This chapter provides information on the specifications of the donor and service antennas
suitable for operation with this repeater, on the installation requirements of the antennas
and on the Repeater installation site and cable requirements.
ATTENTION!!
The BSR-3308 models described in this manual have been approved by Industry Canada
to operate with the antenna types listed below with the maximum permissible gain and
required antenna impedance for each antenna
type indicated. Antenna types not included
in this list, having a gain greater than the maximum gain indicated for that type, are
strictly prohibited for use with this device.
Le présent émetteur radio (identifier le dispositif par son numéro de certification ou son
numéro de modèle s'il fait partie du matériel de catégorie I) a été approuvé par Industrie
Canada pour fonctionner avec les types d'antenne énumérés ci-dessous et ayant un gain
admissible maximal et l'impédance requise pour chaque type d'antenne. Les types
d'antenne non inclus dans cette liste, ou dont le gain est supérieur au gain maximal
indiqué, sont strictement interdits pour l'exploitation de l'émetteur.
2.1 Base (Donor) Antenna Requirements
The Base (Donor) antenna is usually installed outdoors and is either a directional antenna
such as a Yagi or a Panel antenna.
2.1.1 Required Antenna Information
You will require the following antenna information
•
Antenna type and characteristics
•
Height
•
Length and type of coaxial cable required for connecting the Donor antenna to the
Repeater and the attenuation.
2.1.2 Donor Antenna Specifications
•
Max DONOR antenna gain (dBi) = 37 – (27dbi - cable losses in dbi).
•
Very sharp beam pointed to the BTS.
•
Minimum cable and jumper loss = 2dB.
2.1.3 Installation Criteria
Installation requirements:
•
Verify the Donor antenna location provides a line-of-sight to the Base Station and
maximum input power.
•
Install the Donor Antenna at the designated height.
•
Install the donor antenna at a higher level (i.e. floor) than the mobile antenna.
•
Must be installed at a minimum distance of 30 cm for indoor applications from any
personnel within the area.
