How to put three satellites on one cableHow to distribute a wide band signal

The three satellites we are using

101° 110° 119°

101°Satellite

• Has 32 transponders• Each 24 MHz wide• Circular polarity• 16 right hand 13Volt Odd Transponders• 16 left hand 18 Volt Even Transponders• Transmit at 12.1 GHz to 12.7 GHz

110°Satellite

• Has 3 transponders numbers 8, 10, and 12• Each 24 MHz wide• Circular polarity• 3 left hand 18 Volt Even Transponders• Transmit at 12.1 GHz to 12.7 GHz

• Has 11 transponders numbers 22-32• Each 24 MHz wide• Circular polarity• 5 right hand 13Volt Odd Transponders• 6 left hand 18 Volt Even Transponders• Transmit at 12.1 GHz to 12.7 GHz

119°Satellite

The LNB

• Dual output LNB

• Down converted frequency 950 MHz to 1450 MHz

• Polarity selected by13 or 18 volts

• One needed per satellite (no Sat C Kit or LNB)

Data Return Path

The 101°bird is located from 950 MHz to 2025 MHz which includes both polarities

The 110° & 119° birds are located between 250 MHz & 830 MHz

Local Digital Broadcast

5 30/54 250 830/862/950 1450/1525 2025

Channels 2-6 54 to 90 MHz

Channels 7-13 174 to 216 MHz

That gives us room for 12 local digital broadcast channels

Satellite Usage for DirecTV®

• Ku-band 10.7GHz to 14.5GHz

• Ka-band 17.3GHz to 31.0GHz

Formulas

• dBm to dBmv 0 dBm = 48.75 dBmv• Input threshold of IRD- -55 to –35 dBm• RG-6 cable loss-9.34dB per 100 feet at 2Ghz• RG-59 cable loss-11.67dB per 100 feet at 2

Ghz• RG-11 cable loss –6.36dB per 100 feet at 2

Ghz

FormulasLoop resistance

E=I x RE=voltage loss through cable runI=current being drawn through cable (in Amperes)R=loop resistance x cable length (in feet)

Example: Loop resistance of RG6 cable is .04 ohms per foot. RG11 is .02 ohms per ft. LNB uses .3 amp of current.

Operating voltage of LNB is 11-14V for right hand polarity 15.5-21V for left hand polarity

Formulas• Loop resistance exercise• How much voltage is lost through 300 feet of RG6? • I=.3 Amp draw of LNB (300 mA)• R=.04 (loop resistance of RG6)x300 (length of cable

in feet)• E= (.3) x (.04 x 300) or E=3.6 volts• If we start with 18 volts for the left hand polarity and

we lose 3.6 volts, the result is 14.4 volts reaching the LNB. We need 15.5 volts for the left hand polarity to work, so the 18 volt side will only deliver the right hand polarity. NO LEFT HAND POLARITY!!!

Cable Facts

450 MHz

950 MHz

1450 MHz

2050 MHz

Things that affect signal in cable are sharp bends, staples, cable ties, etc.

Amplification

General rules

One of the most often mistakes is overloading the input to a amplifier. To figure out how much signal you can put into a amplifier you do the following:

Output – gain = input

Amplification

Typically you can find the output and gain for the amplifier from the manufacturers specifications.

By overloading the input to a amplifier you will corrupt the data and the entire system will be down.
