The Base (Donor) antenna 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:
• The donor antenna should point to the direction of the base station for maximum
input power.
• Install the Donor Antenna at the designated height.
• Verify that the antenna is in the base stations line of sight (raise the antenna if
