Introduction to RF Antennas used in Reliance jio Installation project

Introduction to  RF Antennas, RET:

Jio uses the equipments of Samsung company and is manufactured in korea. There are two different type of brands of Antennas:

1. Ace
2. Rosenberger

Further Ace & Rosenberg Antennas are divided into separate Bands as follows

1. Single Band
2. Multi Band
3. Penta Band

Single Band:

      In Single Band the antenna is used only for one frequency band and that is only for 850Mhz, but the port order varies. .

Multi Band:

      In Multi Band the antenna is used only for two frequency bands and that is 1.8Ghz & 2.3Ghz but port order varies.

Penta Band:

      In Penta Band the antenna is used for all three frequency bands and that is 850Mhz, 1.8Ghz & 2.3Ghz but port order varies.

There are 3 Frequency Bands:

1. 850 Mhz  (2G)
2. 1800 Mhz (3G)
3. 2300 Mhz (4G)

Ace Antennas:

SINGLE BAND (850Mhz)

MULTI BAND (1.8Ghz & 2.3Ghz)

Rosenberger Antennas:

SINGLE BAND (850Mhz)

MULTI BAND (1.8Ghz & 2.3Ghz)

RET ( Remote Electrical Tilt):

There are two ways to tilt the antenna:

1. Mechanical Tilt - The coverage area is increased in side direction but reduced in central direction.
2. Electrical Tilt  - The coverage area suffers a uniform reducation in the direction of antenna azimuth, the gain is also reduced uniformly.
