Page 10: Installation Location Requirement
Digital Repeater User Manual Installation Location Requirement 1) It is appreciated that the repeater is installed in a cool, dry and ventilated room without erosive gas and smoke and without leakage on its proof. 2) Besides above, a cool and ventilated wall of which sun-proof and waterproof is expected. 3) Besides above, common wall, tower or high pole is ok. - Page 11 Digital Repeater User Manual recommended the donor antenna to be installed in an attic. Testing the signal strength received from donor antenna mounted in site by mobile phone: Please select the top of the building to install the donor antenna if the total floors are less than 7, and must select a place like balcony or platform lower than 7th floor for the donor antenna if the buildings are over 7 floors.
- Page 12 Digital Repeater User Manual In order to avoid interference, please note that the donor antenna should be far away from the following objects. Metal High-voltage line RF antenna High-voltage transformer Repeater is a two-way signal amplifier. So proper isolation between donor antenna and server antenna is necessary in order to avoid self-oscillation.
