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 DIGImini 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.
ATTENTION!!
•
The installer is held accountable for implementing the rules required for deployment.
