The GE 73290 only 4.5dB not very good
There two RCA 10dB Video Signal Amplifier 1-Port and 4-Port it dose good job well as my next door neighbor 1 Port ver of it

I found many similar products in my search, but none of them are the product you were describing in the quote below.

No unlike a single splitter which lower your dB a distribution amp bring back into standerd 7.5dB amplification per port

If the amplifier provides 8 dB of amplification per port, it will increase the signal strength by 8 dB. That is not the same thing as bringing the signal strength back up to 7.5 dB. (Yes I know splitting the signal 4 ways causes a 7 dB loss. 8 - 7 = 1 dB gain.) Plus, they are all 4 port models, not two port models. As such, they will cost more and colt4523 will also need F-termination caps for the unused ports.

[Edit]Not all distribution amps have the same amplification per port and there are plenty that do not balance the splitting loss and output gain that closely. Many of the two-port distribution amplifiers I saw had a 10 to 12 dB gain per port. 10 dB gain - 3.5 dB loss from the split = a 6.5 dB gain.

[Edit 2]I keep getting interrupted. Something else to consider, if the signal really is noisy, the noise will be amplified as well, and amplifiers can add to the noise themselves.

2-Port are out there but not alway idea to use as they must made for Cable Modem and long run and reg splitter
For all I know a 2-Port maybe the better option to go in he case but better be safe the sorry then later.

(Yes I know splitting the signal 4 ways causes a 7 dB loss.)

That reason why I pick 4-port is lower 7/8db output that on top input db.
Keep mind the splitting in side Distribution Amplifier as cuases a loss with in it as well.
-10 dBmV is quite grainy.
0 dBmV is ever-so-slightly noisy.
+12/15 dBmV is near-perfect.
+20 dBmV overloading some TV tuner front ends.
BOTTOM LINE: You want back to around +10 to 15.
Thoses Outgoing RF modulation tuner db output are uselly under power and can become even woste with splitter just like VCR do which like only +5 to 7db output if if that hasn't change.

@SHS At one point you agree that splitting the signal from the DTA with no amplification should still work OK. Then, you say the signal must be brought up to 7.5 dB. Now the signal has to be amplified to +10dBmV to +15dBmV to be perfect. Given your usual inability to write clearly in English, I strongly suspect you are quoting things in the above post that you found on the Internet, without providing a link for context. Do us a favor and provide a reference.

@ colt4523 Ignore this side discussion on amplification for the time being. Unless someone installs cable TV or satellite in people's homes for a living they are probably not going to have the necessary equipment to test signal levels and noise levels available to them. All ordinary people can do is troubleshoot.

If the picture improves dramatically when you remove some thing(s), that tells you that an item that you removed is likely the cause of problem. As a first step, just remove the splitter and the cable connecting the splitter to the HVR 1950. All the cables between the DTA and the HVR-1950 need to be tested separately, without using the splitter. If all the cables perform well connecting the DTA to the HVR-1950, then the splitter likely introduced the problem. ...but that does not guarantee that amplification is needed. There is also a possibility that the splitter might simply be defective.

Yes I agree
It more like just a cheap one, But sometime that not that alway case.
Satellite is all new Ball game thank god it lot eazy vs what we 10 years ago I install all own stuff

At one time I use to install cable line min years in Boise, Idaho in 90's for a few years that just what I recall sorry you know never been good at grammer stuff, it not some as if I was talk to you on a phone.

colt4523 should post a sample of his "noise". Maybe all he's seeing is interlace comb artifacts. In any case, seeing the noise helps diagnose the problem.
