Installation Manual
iSiteC BTS3601C CDMA Base Station
I. Facility requirements
The support on which the directional antenna is installed should be extended out
l
of the platform for at least 0.5m. Proper support length of the omni antenna should
be determined to meet the requirements for the horizontal diversity distance (over
4.5m) between two antennae.
The diameter of the holding support on which the antenna is installed should be
l
60mm~114mm. The length (generally, omni antenna: 1m; directional antenna: 3m)
of it should be determined according to the antenna type and sizes.
A square platform(3m % 3m) should be established 3m above the ground with the
l
bearer capability more than 500kg. And a sun-shading shed should be established
3m above the platform.
A 2m holding support should be fixed to the tower body vertically above the
l
platform so as to install BTS3601C, IAFB, etc. The number of supports is
determined by the number of BTS3601Cs, and the diameter of each support
should be 60mm~114mm.
