Receiver not finding sattelite , Switching from round18" to 3LN HD Dish

[kilingiros]

Hi, I currently have sattelite reception to the box using my 18" round dish. Using RG6 cable that is already wired and working . Switching over to oval 3LNB for HD service. . No signal at receiver. House is wired with RG6 cable. Checked meter reading at garage (thats about half way to receiver) and meter readings are diminshed.Checked readings at receiver an nothing. Dish and transponder are brand new. How can it be that 18" sattelite works but new dish does not through same cable line? Please help!!!

to Satelliteguys!

What type of receiver are you using? Which dish and lnb? Can you find a number on the lnb?

I'll get the receiver number tonight, but why am I not getting a signal at the point where the cable goe into the reciever?

At this point I have no idea. What are you using to measure the signal?

[h=1]I'm using ACUTRAC III Plus Ka Hi/Lo Ku Satellite Signal Tracking Meter[/h]

Use the recvr meter and see what you get, you said you switched to a 3lnb oval ?
You'll need a Slimline dish3 or 5 if you want HD.

I'm using Slimline5, cannot pick up any signal using receivers meter

Slimline 5, NOT a SWM, correct .... if its a Swm, its looking for the Power Inserter, if not a Swm, you get no signal on any sats, probably an alignment issue, btw, how long is the run from the Dish to rhe recvr ?

Did you replace the mast with a 2" one? Is is plumb? This is important!

 

[kilingiros]

Yes its a slimline5. Its about 100 feet (2 X 50) run of RG6. The mast is the new 2" one and its plumb. I get SAT signals at the dish but when I connect the cable to the reciever, there is no signal at the opposit end (receiver end). When I check the signal strenght at about the 50 foot mark (that where theres a coupler) the signal is diminished. The cable I'm trying to use is the one that works fine with the older 18" round dish. Seems to me that if one dish can make the entire length of the cable, the other one should as well, right?

Apparently not! Ka signals (hd) don't work as well across long cable lengths as the ku (sd) signals do. Generally 125 is the practical limit. It sounds like there may be an issue with the cable. Can you replace it with one single piece? Does the lnb have one output or four? If one, you need a power inserter. I think that's the real issue here.

 

[kilingiros]

Four outputs, is there a booster I can put inline?:shocked

Replacing the canle is my last option one all otrher are exhausted since the cabel is already wired behind the walls.......Shouldnt I still be able to ket ku(sd) signal anyway?

Sorry about the spelling, fat fingers!

Replacing the cable is my last option once all others are exhausted since the cable is already wired behind the walls.......Should'nt I still be able to get ku(sd) signal anyway

Yes you should. Since it's not a swm lnb, I am suspicious of the lnb itself, or maybe still the cable. Can you run a new cable from the dish inside? That would eliminate it as the problem and point to the lnb. Is there a model number on the lnb?

 

[Jimbo]

You say you have signal at the dish, but nothing at the recvr ?
Is that with the meter or the recvr meter ?
Sounds like your picking up the wrong Sat.

Yes that is correct, signal at disk (on the roof), no signal at opposite ent of cable (basement). That's usiing the Acutrac III meter, not the recvr meter.

I too though it migfht be the LNB so I purchase a new one with same results. Sorry, I do not have a model number...............

Ar this point I would start with a NEW piece of Coax and make sure the connectors are in good shape.

I'm going to do that this weekend, run a "test" line from the dish directly to the tuner, see what happens......
