MMDS Set-up Complete Beginner

I assume then you have also performed a reset and scan again after the flash...

 

First of all this site has some great reading and thanks to all especially senior members
Hope someone can answer my question.
trying to setup eurovox tx for a friend. he has the old jerrold box which seems to be pickin up analogue channels. he is getting a couple but some are scrambled.
he is not sure how long the aerial is there.
how would i know if he had a downconverter on the aeriel?
would you have to replace the whole aerial or just add a downconverter to it?
I suppose i could bring my box and power supply and test but could this do any damage to it?
any help greatly appreciated

 

Your friend get no analogue mmds channels without a downconverter at the aerial. Beside that there should be a powerinserter which feed the downconverter with power.

 

Which is the best aerial to use with Starview 3?? What is the order of connections from the box to the aerial with downconverter?? All help would be great. Cheers

 

The box and ariel you select are independent decisions.

You need a working ariel (with downconverter + power inserter). You also need a suitable box DVB-C or DVB-T (Cable or Terrestrial).

If you are on Ch0ru$ MMDS, you need a terrestrial box (eg. eurovox tx, dreambox 600t, the box-t). If you are on NTHell MMDS you will need a cable box (e.g. starview 3).

The ariel generally has the downconverter installed on it. The coaxial cable screws into the downconverter and is fed down to your TV room. In your TV room, you will have a device which plugs into the mains. This device is the power inserter and will have an input (from antenna) and output (to TV or Box). When you connect the coaxial from the ariel into this, it sends power back up to the ariel and receives the signal from the downconverter. The output from the power inserter is then connected to your receiver (dreambox, starview, eurovox etc.).

 

Hi All

I have an EYEtv hybrid usb connected to MMDS i can scan from the eyetv software and receive all the channels on my pc but they are encrypted is there any way to decrypt the channels on the PC??

 

hi guys,

there seems to be a lot of people looking for the downcoverters that cho**s supply. Just got off the phone with the American divison of Transystem ( the company that supplys the downconverters to cho**s) and they sell indavidual units for $28 plus p&p...
hope this helps...

 

In Mayo N*L are using cable boxes. What downconverter range is used and where can these be sourced.

I could be wrong on this, but I think you don't need the downconvertor for N*L mmds, I am sure I saw a thread about this recently, and I think the downconvertor was the reason you needed a TX box for Ch@@us mmds but not for N*L mmds. But this a bit technical for me so don't take it as gospel!!

 

You need a downconverter for any form of mmds.
The signal is being transmitted through the air at ~2.5Ghz.
The grid picks it up then its downconverted to a lower frequency range so as it can travel through coaxial cable without major loss.
A 2.5Ghz signal wont travel far through coax cable without huge loss and reflection.
The downconverted frequency range is formed by subtracting an intermediate frequency IF from the input frequency.
This lower frequency spectrum is then fed to the set top box which can decode it.
The actual signal contains data coded in different formats.
Chorus MMDS uses the DVB-T transmission format while NTL MMDS uses the DVB-C format,that is why different receivers are used.

 

Anybody know the network number for NTL mmds for input to a sagem box (cable) to receive RTE etc . Box is asking for this and the frequency and symbol rate. I know the symbol rate and the starting freq of my aerial.

How do I get in contact with the Transystem guys. Do you have a code number for the aerial I need to rec C*****s.

 

google "transystem downconverter" click the first result (not the sponsored links) on that page the first downconverter is the one we use "AiDC+ Integrated MMDS Downconverter" click the "contact us" button at the top of the page. then under the U.S.A heading use the telephone number for the east coast divison. when your talking to him he will tell you that the downconverters are made in ireland just tell him that dosent matter that you would like to go ahead and order one anyway...

Hope this helped...

 

I live in a Ch***s MMDS area, we had an old chorus aerial(moon shape)from many years ago which I reinstalled on the roof at the weekend, using the Box-t and power supply from s&c I could get no signal on the auto-scan or on any of the frequencies mentioned on here. As the box-t works fine in my brothers house with Ch***s MMDS subscription I am putting it down to the downconverter on the old aerial being busted. I have ordered the downconverter recommended on here. Am I missing anything or if I replace the downconverter, should I be good to go ?

 

@ wiseguy25
Thanks

 

you can buy down converters in Ireland google "downconverter Ireland"

 

Wonder who owns that site must check whois. Just checked bit pricey and they actually give their name,address and phone number.

Not unusual but with the CC cracking down on those selling MMDS equipment stating that it can be used on "other" boxes isnt very wise.
