Stormy season Preparedness 2009

Slide 2

Rain Fade Rain, snow or even rain-filled mists passing overhead can decrease the power of the approaching signs. This outcomes in FREEZING or NO PICTURE. Exuberant deluges can bring down the level of the approaching Ku-band satellite flag fundamentally; this may extremely debase the nature of the signs or even interfere with gathering altogether. As in the precipitation or rain filled mists, the nature of the flag begins diminishing. On the off chance that the following is not at pinnacle, the flag will be lost quickly. Most extreme pinnacle following will diminish the time length of "NO SIGNAL" amid precipitation.

Slide 3

Rain Fade - To Counter Act... To Counteract Track the radio wire to crest level with Signal Strength (force) & Signal Quality (BER,MER) & Skew to greatest level. Impact of Noise on Digital Systems (Gradually Poorer Quality/MER) 7.0 dB MER half Quality 9 dB MER 70% Quality 6 dB MER 25% Quality 14 dB MER 99% Quality No change No Signal Freezing The photo stays same from 14 dB MER to 9 dB MER. It begins solidifying at 7 dB MER & at 6 dB MER there is No Signal. This demonstrates the following must be done till pinnacle MER/Signal Quality is accomplished for a specific dish reception apparatus.

Slide 4

Objective At the finish of this session we will comprehend the - Importance of Signal Strength. Significance of Signal Quality/MER/BER. Significance of SKEW. Wellbeing focuses.

Slide 5

Important Points for Installations Track the Dish Antenna with most extreme Signal Strength (force) & Signal Quality (MER/BER). Do SKEW with most extreme care to accomplish greatest flag quality (MER/BER) for every one of the transponders. Affirm the readings of the considerable number of transponders to crest. Every one of the Bolts, Screws, Nuts ought to be fixed to greatest level. Over fixing ought to be stayed away from. Take after the Look Angle Chart for all the three edges Azimuth Angle, Elevation Angle (Inclination Angle) & Polarization (Skew) for the specific territory. Lean toward divider mounting for greatest establishments & check the divider thickness before establishments. Pole ought to be dependably in 90° wrt flat plane (Ground). Check the pinnacle following by squeezing every one of the four sides of reflector one after one & see that the readings ought not increment. It ought to abatement when squeezed.

Slide 6

Important Points for Installations Put all the fundamental circles to the links any place required to stay away from water entrance in the STB. Sharp edges to be anticipated with twofold sided tapes settled to the link. Keep away from link steering through moist territories. Utilize Sealant at all the through openings in the divider to stop water entrance, link cuts, creepy crawlies migrations and so forth. Sat meter ought to be full charged before any establishments. All F-connectors ought to be settled according to our standards just as it might bring about no video for a few channels. As we are taking a shot at extraordinary high recurrence so connectorization must be done accurately. Link ties, P-clasps to be appropriately settled to the links. No over fixing of the link ties & P-clasps to be done on the link. Legitimate ventilation for STB to be checked before introducing it.

Skew Angle Setting-Sharp Universal Single LNBF The LNBF (Universal Sharp make) has markings on the top. There are, say 9 divisions on each agree with an inside point checking amidst the LNBF. Every division compares to 5 degrees estimation The divisions must be balanced by the polarization given. For eg. Mumbai\'s Polarization is - 43.00 deg, so we need to set at 8.2(approx) division of the LNBF with the inside purpose of the LNBF Clamp. Focus Point of LNBF CLAMP Center Point of LNBF Clamp - 43 degree for Mumbai

Slide 9

Skew Angle Setting-MTI Universal Single LNBF The LNBF (Universal MTI-Reliance make) has markings on the top. There are say, 5 divisions on each agree with an inside point checking amidst the LNBF. Every division relates to 5 degrees estimation The divisions must be balanced by the polarization given. For eg. Mumbai\'s Polarization is - 43.00 deg, so we need to set at 8.2(approx) division of the LNBF with the middle purpose of the LNBF Clamp. Focus Point of LNBF CLAMP - 43 degree for Mumbai Center Point of LNBF Clamp

Slide 10

Skew Angle Setting-MTI Universal Single LNBF The LNBF (Universal MTI-Reliance make) has markings on the top. There are say, 5 divisions on each favor an inside point checking amidst the LNBF. Every division relates to 5 degrees estimation The divisions must be balanced by the polarization given. For eg. Mumbai\'s Polarization is - 43.00 deg, so we need to set at 8.2(approx) division of the LNBF with the inside purpose of the LNBF Clamp. LNBF CLAMP Center Point of LNBF - 43 degree for Mumbai Center Point of LNBF Clamp

Slide 11

Skew Angle Setting-X Power Universal Single LNBF The LNBF (Universal X Power make) has markings on the top. There are say, 8 divisions on each agree with an inside point stamping amidst the LNBF. Every division relates to 5 degrees estimation The divisions must be balanced by the polarization given. For eg. Mumbai\'s Polarization is - 43.00 deg, so we need to set at 8.2(approx) division of the LNBF with the inside purpose of the LNBF Clamp. Focus Point of LNBF CLAMP Center Point (Ref) of LNBF Clamp - 43 degree for Mumbai

Slide 12

Importance of SKEW is the MOST vital conformity for following in BIG TV. As we are utilizing two polarities (Vertical & Horizontal), so SKEW must be done unequivocally. Track the satellite (MEASAT-3) with Transponder 16(12523MHz, Vertical high) in the first place with most extreme flag quality & flag quality (MER/BER). Next move to Transponder 22 (12683MHz, Horizontal high) & track to most extreme flag quality & flag quality (MER/BER). In both the circumstance the SKEW ought to be done correctly. While we alter TP22 to greatest Quality (MER/BER) by Skewing, we have to backpedal to TP16 at the end of the day & check the Quality (MER/BER). In this circumstance we will get a low flag Quality (MER/BER) on TP16 than what we have followed at first. Presently again we need to conform the SKEW to such a degree where we will get a most extreme flag quality (MER/BER) for both TP16 & TP22.

Slide 13

Importance of Skew For Eg. Introductory SKEW of TP 16, MER=14dB Initial SKEW of TP 22, MER=13.2dB (Here in TP 16 MER goes to 13dB) Final SKEW of TP 16, MER=13.8dB Final SKEW of TP 22, MER =12.9dB Check every one of the transponders readings for most extreme flag quality (power) & flag quality (MER/BER).
