splitting digital cable using 2 splitters and a 135ft run?

hi, my current digital cable setup right now uses only one HD television. the main line coming into the house goes into a 3-way splitter. the 3.5db goes to the cable modem, one 7db goes to the phone, and the other 7db goes to my living room HD receiver. i bought some rg-6 burial cable to run a cable feed into my garage (this tv is not HD, i just want the digital cable), which will be approx 135ft.

my question is if i tap into the 7db port and split it with a 2ghz 2 way splitter (1 cable to HD receiver in house + 1 cable to digital receiver in garage) will the 135ft run hurt my HD signal on the tv inside the house enough to be noticeable? would there be another way to do this? or is it just the kind of thing i'll have to just do it and see what happens?

thanks for reading, there are lots of questions about cable splitting on here but i didn't really see any with long cable runs involved...

    Your sign splitting success relies upon on the quantity of sign left on your cable after it is going interior the direction of the 1st splitter. i could attempt a 2 or 3 way splitter as an test first and hook one leg right into a television and see in case you have sufficient sign. if your sign is only too susceptible you will desire a plug in amplifer the two put in place in the past or after the 1st splitter. in case you have a stable sign you're stable to bypass with only the splitter. I actual have a 4 way splitter feeding a three way splitter on my cable and nonetheless have a lot of sign without using an amplifier.

    I would put the 2 way splitter on the 3.5db port. If you put it on the 7db port you will cut the signal down to about 10.5db. Then there will be cable loss. But that will only affect the TV at the end of that run. A better option would be to buy a 4way splitter to replace the 3way.

    You need to use a signal amplifier to do a satisfactory job.
