Trouble with Signal !

Re: Trouble with Signal !

If you want to eleminate the Motor for just a moment to test...Then all you have to do is:

1) Put the motor on the Satellite you want ( Say Astra or Hotbird or whatever you want) choose the Channel which in the evening you have a good signal.
2) Switch the receiver OFF.
3) Unscrew the 'F' connector of the LNB which goes into the Motor.
4) Unscrew the other 'F' connector of the Motor and before connecting them together you must get a 'F' adaptor so that you can connect the two cables at each end of the Adaptor.
(This 'F' Adaptor has two threads at each end where you can connect two 'F' connectors)

When you have connected the two Connectors together switch your Receiver 'ON' and see the signal level.

I have attached an image of an 'F' Adabter

@alfred_1
oohh i understand you now... you mean the cable from receiver to conect with the LNB, without going to motor...I need to try thi ,thanks ...i inform you when i will try it

Re: Trouble with Signal !

Only a comment, you must know than this type of F double connector have a lot of rate signal/noise, it have lost signal. To try in order to fix an error, is ok, but to join two cables is not appropiate.
Regards.

Its always the normal rule to have a complete cable running from one point to the other.....having said that, I must point out as well that one cannot say that ''this type of 'F' double Connector has a lot of Signal to noise ratio'' it doesn't, because otherwise we can also say that normal 'f' Connectors also have a signal to noise ratio.

What we can say is that there will be a slight attenuation of the signal but not a lot. In fact if one uses one of these double connectors and shields it properly with Amalgamating weather tape and checks the Signal level on his reciever, before and afterwards, he won't see any difference on the level of signal provided that there isn't a long run of cable between Receiver and LNB.

Now another thing one must also remember is that normal 'f' Connectors should be shielded either by a 'rubber cover' or by Amalgamating weather Tape to protect them against the rain and Sun rays.

Re: Trouble with Signal !

That 'F' connector barrel is fine to use in any installation the loss of signal is negligible and you would hardly notice it at all. The suggestion for using this type in this situation is not a permanent fix just to test that the LNB is in fact OK and maybe a problem with alignment.

So alfred_1 is correct this can be used just for testing purposes and it will be removed afterwards, I also agree that a single cable run with no breaks in it are always the preferable method when installing a system

Re: Trouble with Signal !

I am not an englishman, and my english isn`t so good as yours. I understand you are right, but I only wan`t to say that I have a connector to join 2 wires and the signal attenuation is high, so the signal is poor. There is a high lose of signal using this connection, so I only say that to make a try in order to fix a problem is a right connector, but I don´t recommend it to definitve installations.

For me that kind of connection makes you lose too much signal, so it is best to use cables without splices and splice connections also use other cable tv antenna connectors without F, and is better, at least in my case .

I apologize about my english, but I learned english at school, and I mistake sometimes when I post something, I think this not must be a reason to reprimand anybody. I don`t like to use ****** translator, because, translations are worst than my own english. Have you understood what I wanted to warn with the message? OK, double F connector, signal loss.



This is all I wanted to say,I did not want to criticize your solution, only warning signal loss.

Regards.

My dear Satfinder, first of all I am not an Englishman Maltese in fact, and let me assure you that I have no intention of reprimanding anyone, least of all you.

As I stated immediately in my opening paragraph...that it always best to have a complete run of coaxial cable instead of making joints anywhere on the run of cable. That’s an undisputed fact.

All I am stating is that if anybody, by any chance, needs to make use of a 'Male' or' Female' 'F' Connector (properly shielded by Amalgamating weather tape) they won't experience a big loss on the signal but a slight (mostly not even noticeable) signal loss.

I did it temporary once or twice on one of my own Dishes (left it for about a week when I had to move my Dish to another location) and there was absolutely no signal loss at my Receiver end when compared to a complete run of co-axial cable.

I hope this clear the matter conclusively

That 'F' connector barrel is fine to use in any installation the loss of signal is negligible and you would hardly notice it at all. The suggestion for using this type in this situation is not a permanent fix just to test that the LNB is in fact OK and maybe a problem with alignment.

So alfred_1 is correct this can be used just for testing purposes and it will be removed afterwards, I also agree that a single cable run with no breaks in it are always the preferable method when installing a system

Thank you for your understanding my point.

Re: Trouble with Signal !

Well actually I was going to mention it to you that perhaps your 'F' connector might have been defective because you shouldn't have had that big loss.....anyway its good to share our knowledge with one another because that way we share our experiences.

Best Regards my friend.

Re: Trouble with Signal !

Well the best thing is to change it....also check your whole 'extension cable' which you use when moving your Dish .

Re: Trouble with Signal !

between the lnb and the decoder if the calbe is long was helping to a better receipt

Re: Trouble with Signal !

I think is metter of LNB.... now is the same day & night ... no change ...
i inform you what ive done ..

Re: Trouble with Signal !

@Satfinder
i mean for my problem ,trouble with signal !!!
in the beginig i had signal for all frequences at night, now its the same day & night... half of frequences dont have signal :S

[badboy20]

Re: Trouble with Signal !

I have the same problem .
But this problem with losing signal at day,is just with the DM500s ,i have an old receiver and when i conect the old receiver he has signal on the same postion that on DM500s dont have ..hmmm realy strange !
And yes its everyday the same ,on sunrise the signal is week ,at night great signal !!
So i think its not the Lnb or Motor ,how can it works good on other receiver maybe we have installed something wrong ....
and yes if this information you need ,at the first days 2-3 days when i bought the DM500s the signal was good night & day ...
I dont think that is problem that i flashed diferent images ,if is the image problem would be problem and to other users ..

Re: Trouble with Signal !

@Satfinder
Whats a external fan and PC fan if you can tell me ,or can you send me a link how to do that ,you mean my DM has a bug , if it is up to DM i think i can change it for new one ,i have 1 mounth that i bought it !

Re: Trouble with Signal !

These are the kiddies for cooling with temp control to keep things cool I run these with all my kit xbox playstation, sat box and apple tv all in sealed cabinets, the sensor switches the fan on when needed and ramps up the speed when it gets hot keeps my gear at the right temp whatever I am doing.

I think they are about £7-00 well worth it to keep your kit cool..

Re: Trouble with Signal !

i have read that its a problem with the q72 transistor if you ****** it you will find infomation on this.

Re: Trouble with Signal !

check your diseqc device ,,,
do u have problem with other sat?!
