HOW TO DISTRIBUTE CABLE TV CONNECTION TO TV



WHEN WE GET FINAL SIGNAL AFTER CONTROL ROOM 200 MTR AHED CONNECT A ANATHER AMPLIFIER FOR RESON, GET BETTER SIGNAL FROM 200MTR WIRE LOSSES.
OUT PUT FROM FIRST AMPLIFIER GAIN =90 DB , SLOPE = 95 DB
AFTER 200 MTR THIS CABLE LOSS ABOUT GAIN 20= DB, SLOPE = 25 DB
SO RESULT WE GET NOW GAIN- 90 DB-20 DB = 70 DB
                                                SLOPE- 95 DB- 25 DB =70 DB
NOW HOW TO INCRESE THIS SIGNAL GAIN
THIS INPUT GIVE TO NEW ONE AMPLIFIER
AND ADJUST THIS GAIN SLOPE CONTROL UNTIL OUT PUT
                                                                GAIN – 90 DB, SLOPE – 95 DB
AFTER THIS, THIS PROCESS WILL CONTINUE FOR EVER
MEANS EVERY 200 MTR DISTANCE CONNECT A AMPLIFIER
AND GAIN SLOPE ADJUST LIKE UPPER METHOD
