Cable tv splitters

Tlg, Cable TV is a very low voltage system. The only way to get a surge big enough to damage equipment thru a cable line is a lightning strike or a downed power line crossing it. Your cable drop is suppost to be grounded at your ground rod before it goes to the splitter to prevent this from happening.

Ozzy, A 300 ft drop is very long. Most peoples drop is 50 ft or less. You already have an amp and still have a bad signal. Sounds like a tough situation. I don't deal with the distribution part so can't realy help there. Sounds like its a new pole or Dish.

As far as how many lines you can have to your house, they only allow one per unit. So if you live in a single family dwelling you can only have one. What riley804 is talking about is running a seperate line from the splitter that is outside. Technically it doesn't matter where you split it as long as the signal is good when it goes into your equipment.

Hi, I am a cable technician. Anytime you split the signal with a 2way splitter you lose 3db. Also the signal is not scrambling. The reason your picture was pixelating is from a weak signal from your coax. If your old splitter was not rated at 5-1000 mhz or more that can affect signal quality. So if you have more splitters than you need remove them. If you need all the cable lines you have then you need an amplifier. If you want to do this yourself make sure the amplifier you buy is rated 5-1000 mhz or more. Also you need to install it before any splitters. It does no good to amplify the signal when it is already weak at the end of the chain. This also has the benefit of boosting the whole system instead of just one jack. I would just have the cable company install the amp for you because they only charge you $50 to do so and you own the amp afterward. Considering the amp will cost you $50 to buy yourself you can't beat it. Also if you have 4 or less outlets and need an amp Comcast will install it for free. I'm not sure what cable company you have but just ask them what their policy is.

Good luck

Having an amplifier installed only applies if you are in a house. If in an apartment it gets more complicated. Also if you don't own the house you will need written premission from the owner to have an amp installed as it requires drilling holes in the house. Sometimes it will be better to have the outlet rewired because the wire may be old RG-59. A tech can find out what is best for your system by useing a signal meter to test signal strength at different points in your system.

Hope this helps.

Another thing to consider is if you install the amp yourself it is possible to have to high of a signal for the internet modem. This is why doing some of this stuff yourself without the right tools and knowledge can be problemattic.
