Where to put inline amlifier

[momi]

Hello there,


great forum....

I have a dish with main reflector and sub-reflector with 9 LNBs, 9x1 Diseqc switch and DreamBox dm800se....so I was wondering where to put inline power amplifier:

1. after diseqc switch and before dreambox ?
2. or to use 9 inline power amplifiers after LNBs and before Diseqc switch?

My cable run is over 50 m.



Thank you!!

The best place to put an inline amplifier is in the trash... LOL! I am almost serious!!!

150 feet of good quality coax cable should not need an amplifier.

A proper dish size, good quality fittings and quad shield RG6 coax cable is all you really need. In most cases an inline amplifier will actually degrade your signal quality.

Thanks dude,

but my cable run is a lot more than 150 feet, and i have some diseqc that has a significat loss...any good amplifier...? a selective one?

I have never got one of those in-line amps to improve anything. Most of the time it would make things worse.

I agree, inline amps are a waste of time and money, from my experience. Also, Brian (SatellieAV) is not just some dude, he is a dealer (been in the business for quite awhile) and you can pretty much take his advice to the bank.

How long of cable run? What type of coax?

What size dish and satellites that you are fixed on?

Why do you believe that the system needs amplifiers?

Inline amps are best installed near the LNBF, but I have only used for 100+ meter runs when there were little other options without significantly spend big $$$$.

Some are better than others and have cleaner amplification, but I don't think there is much difference in the cheaper ones that you find online or in local electronic retailers. Inline amps are really the last option that you should try.

Maybe consider a better switch? Some have very clean amplifiers for near zero insertion loss.
