The following guidelines apply to the requirements described in 

page 65 and 

 on page 67:

Perform electrical measurements at room temperature (+20°C to +26°C) 
unless otherwise specified

For main and diversity path antennas, make sure the antennas (including 
contact device, coaxial cable, connectors, and matching circuit with no more 
than six components, if required) have nominal impedances of 50 



 across 

supported frequency bands.

All tests (except isolation / correlation coefficient) —Test the main or diversity 
antenna with the other antenna terminated.

Omni-directional in azimuth

-45

> 0 dB

Vertical linear polarization is 
sufficient.

> -6 dBi (preferably > -3 dBi)

Gv and Gh are measured and 
averaged over -45

Maximum gain and uniform 
coverage in the high elevation 
angle and zenith.

Gain in azimuth plane is not 
desired.

> -5 dBi

> 10 dB in all uplink bands

< 2.5:1

Any other than LHCP (left-hand 
circular polarized) is acceptable.
