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
• Yagi type or similar – 12 to 20 dBi gain, very sharp beam pointed to the BTS.
• Cable and jumper loss is at least 2dB.
• Example of antenna's typical specifications:
Gain: 8 dBd (=10.1 dBi)
VSWR: < 1:5:1
Impedance: 50 ohm
2.1.3 Installation Criteria
NOTE: Verify that the antennas meet requirements described in section 2.1.
Installation requirements:
• Select a location for the Donor antenna and verify that there is enough signal strength at that
location.
• Install the Donor Antenna at the designated height.
• The antenna should point to the direction of the base station for maximum input power.
• Verify that the antenna is in the base stations line of sight (raise the antenna if necessary).
• Install the donor antenna at a higher level (i.e. floor) than the mobile antenna.
