Wireless system

[courghan]

Hi, I was wondering if anyone knows if it is possible to transmit the signal from the dish to the decoder with a wireless signal. I am renting a place so I can't wire it.

Thanks a lot!

No, you need to be able to transmit 13/18 volts and 22Khz tone controls to the LNB, then four different bands/polarities of signal back to the receiver, not possible.

There are cable connectors which will fit under a door or window.

Cool, I didn't know! Do you know who does sell these connectors in Ireland or the UK??

....just for curiosity, to be possible to the wireless, would you need an actual sat transmitter attache to the dish??

Thanks again!!

No, it really isn't possible, there are hundreds of people living in fringe reception areas where they require huge dishes and would benefit from a wireless solution.

Don't you have a local satellite dealer, Maplin or a B&Q warehouse - eBay?

The German Lidl system came with one picture here don't know if the UK/Irish one was the same.

Damn !

Curses !!!!

Just spent 10 minutes looking for that very piccy and couldn't remember where it was O-Ha

Anyway it is not possible to transmit voltage and current in that way given the present state of technology. Guess the flat coax is the next best thing

You can get them from

If you live in Dublin, Crumlin area. The do a mail job too. Or you can try Zintec in Greenhills rd.

Rolfw, wouldn't it be possible to hook the LNB up to an external power supply of a 13/18 Volt switch and somehow remotely control this and then get the TV signals back to the reciver? When returning the TV signal another signal could "tell" the receiver what voltage was used on the LNB so the V/H polarisation would be correct...

Well it isn't only H/V switching, but also High/Low, so whilst I guess that if someone threw enough money at a solution and had power available at the dish, then they could work something out, but it would be very expensive.

Better and cheaper to build a littl insulated box for the receiver and use a video sender to transmit the digibox output back to the house.

There was a wireless solution I saw at Mediacast some time ago, but at that time it only dealt with H/V and did this by shifting the polarity to a higher frequency and then using point to point microwave, the slave unit accepting a standard LNB cable and down converting the required polarity. Whether it would be feasible to do it with high and low as well is a different matter.

Thats right, we did just that at a sight where we could not get the signal because of a rather high mountain. So get this:

Distance to dish: ca 3.7km. At the dishsite a plastic box for mains electrics 80x80x40cm. Inside this box a digital receiver,powered by 12V,a 95A Car Batterie and a 12V Videosender System with receiver for the infrared remote. The Antenna of this 2.4Ghz System got replaced by a 75cm prime focus parabol and a microwave antenna where the LNB used to be.(self made). Also at the site the normal dish,1.2m motorised via diseqe and a 50W solarpanel to power the whole thing.

At the receiving end again a parabol with microwave antenna connected to the receiver of the videosender system and of course the remote.

It works perfectly well and is also, after moving the receiving antenna and reallining the system,not interfearing anymore with our 1Gb Broadband, also coming wireless over 5.5km, but thats another story.

The things you have to do, living in the hills...........

wireless sat link .......

The normal way would be to site the sat receiver close to the dish, then use a videosender to relay picture, and also remotely control the sat receiver from some distance away.

For distances over 40m (ish), you can get special 2.4 Ghz yagi antenna and booster amps, but i'm not sure if that's legal in the UK .....
