I have worked in the area for roughly bout 6 years and here are some tips
I can share with you:
1. Get to know your equipment in the headend
a. lead amp, combiner, channel modulaters, splitters, cable line, taps, power supply, power inverter.
Train yourself in how each works and how they deliver the signal to the home
TV or internet
Cable line is like the old days of rabbits ears where the TV tower would fire off a electric voltage in the air for your rabbit ears to convert the signal to a picture
The same voltage is there however its sealed in the line(750.500) as that is why its important to maintain the line often as Cold weather and other possible problem can be there which will hamper the delivery in affect your business
There are alot of RF signals in the air which can affect the delivery of the signal airplanes, walkie talkies, microwave, ham radio etc even the earth core can affect your signal
as cable uses same techno- radio frequency (RF)
you need to use good shielded splitters to prevent these problems as much as you can
Proper splitter balances out the signal as to much power from the tap can sometimes burn out your color guns on your TV or heat up your modem adapter and burn it out
------------------------------------------------------------------------------------------
Splitters cut back outlet you need to apply the proper ones and do a bit math in how much cut back there is to get the best delivery this is also adding the amount of cable being used
delivery of the internet/cell phone/Tv will be impacted if lines are not maintained
example: look at the hydro guy he walks and looks at lines checks them
as cable tech you have to follow suit to prevent problems get a head of the game
remember the voltage is the one that delivers the signal. The longer the run
power can be weaker. Its like a garden hose. hose gives off 10 gallons
den its sprouted in lots of ways still its 10 gallons however balance and tuning is the secert to get the best flow out of the 10 gallons to get the max out of the amount you only have
thats what cable is
Other wise you will spend big bucks on a tech and money goes out as the goal should be to have the money to stay in your community so you can get new equipment when needed so your business can grow
however true to fact there will be times you will need a seasoned vet in this area but only when needed
The end drop should have a splitter grounded properly attached to the areas selected with a grounding block perhaps to a hydro mast
split the RG 6 cable to areas where you wanna add the connections (TV, Modem)
And make your sure all connectors are sealed crimped tightly
The internet in the headroom is connected to the combiner which also in turn
goes through the cable line
That is the send
Now the return
The power condition of the drop line and connectors can have a impact and create a considerable amount of noise heading back which in turn will affect the internet or cell phone.
And not using the reccomended splitter plays a role in the whole scene.
The damaged line 500.750 also plays a role in the send and return
This will in turn help understand about tuning the amps if you can relate to these concepts as I noted
Think of your head room/headend as a radio dial
