Here is a list of the transponders
What frequencies does Foxtel Satellite currently use?
ie: what frequencies (range) are used across the coaxial cable that goes from the dish to the decoder?
Look Here -> |
Here is a list of the transponders
As above, all Ku-Band
So would that suggest around 11,700 MHz through 12,400 MHz?
Edit:
Just looked at 2 amplifiers that are used on a Foxtel satellite service (1 on each of the 2 cables from roof to mdf, before the cables connect to a 4 way splitter that then goes to each of the 4 units) and the amplifiers say they are 47-2,400 MHz.
So what frequencies does sat Foxtel use?

did we miss read the question
ie: what frequencies (range) are used across the coaxial cable that goes from the dish to the decoder?
the answer has to be 950mhz to 2.1ghz ???? cant be anything else ???
I think the OP is a curious 'Newbie' because of his reference to 'Foxtel' satellites when its OPTUS who provide the service and companies like Foxtel and many others rent the facility.
Back when Austar still existed, all sorts of stories abounded that you couldnt receive their Satellite signal outside their serviced area and there were 2 completely separate transmissions for each company.
Dont confuse my comment with 'Beaming' as thats done to get the best possible signal to a given area but it all still comes from the one Satellite.
Both Companies were using different encryption systems along with different programming but beyond that, it was all carried by the Optus owned satellites along with a myriad of other material.
Think of it like the terrestrial FM Radio band, you have a number of Stations (Transmitters) operating between 88 and 108 Mhz and that is all picked up by the antenna and fed down into the Tuner for you to select what 'channel' you want to hear.
An LNB incorporates an antenna to receive the signal, and a broadband amp to send it down the cable to the receiver.
The exception to the above would be that used in Radio Astronomy where the antenna is designed to be highly sensitive to a narrow or single frequency as would be any amplification used.
It really doesnt matter what sort of antenna you use or how the received signal is fed to a receiver because a little or a lot of the whole known RF band, 200khz to ??Ghz is picked up and its up to the Tuner etc to ignore what is of no use to you.
I stand unequivicably behind everything I say , I just dont ever remember saying it !!
An LNB incorporates an antenna to receive the signal, and a broadband amp to send it down the cable to the receiver.
and a mixer of course and the local oscillator in the lnb to give the output to the broadband amp to send down the coax at 950- 2100mhz
950- 2100mhz.
Yes, that 'range' is the downconverted frequencies from the LNB.
regularusername, you've started several threads asking about frequencies.
It might be helpful if you explain exactly why you need all this info.
What are you hoping to achieve?
but would that take away the fun ???? hahaha mtv
Thanks for the info.
I will start a thread asking questions about what Im trying to acheive now that I know the frequencies.
For the record I am a telecommunications technician that has a project involving a building that has Sat, FTA and about to get NBN HFC. Will explain in much more detail in new thread.
Edit:
What frequencies does NBN HFC use (from the incoming cable into the premise to the Arris modem)?

You've mentioned you're a telecommunications technician, but how much experience and test gear do you have for SMATV and MATV distribution systems?
