Wireless saorview transmission?

Healy Rae Permit Holder

I would like to know if there is a way to transmit a saorview signal from one house to another, i cannot connect houses with a cable due to a main road in between the 2, houses are 100 metres apart and no obstruction, mountain edge just hindering one house, every avenue explored and cannot get good solid signal, freezing alot, the other house has good signal no freezing, an experienced tv and sat engineer has exhausted all ideas to get signal, i know saorsat is an option but would like tv3 and 3e. If there were an option without being too expensive that would be great thanks.

What type of 'main road' is it?
Farmers often have electric fence cables going across rural roads to their land on the other side of the road.

running a cable is easiest option if you can go across the road and its just 100 meters. You would need cable TV isolator at the cable ends to block any AC power current from flowing on it

It would be possible to setup a tv server in one house and connect from the other house via wifi. It would work expensive if your starting from scratch though.

I like the sounds of that idea, what is a tv server?
I uses wifi for internet its a router that has a 3 dongle plugged into it, running a cable is 100% not possible its a secondary road. The other house dont have internet but i could buy a ready to go dongle and router to get them wifi too.

No way under the road for a cable? Say a drain or something?

There is a stream but i would need to go out my way, the biggest problem would be burying the cable, i would be digging up lawns, a concrete drive, a tarmac drive on other house and breaking footpaths then, sky digital would be the solution then i say if i am faced with that.

A tv server is basically a computer with a tv tuner in it. I have an old laptop in my house with a tv tuner, I can then watch tv on my smart tv, laptop phone etc.

Something like this might be easier to setup: http://www.silicondust.com/products/hdhomerun/hdhomerun-dt-united-kingdom/

You would then need to setup a wireless link between the 2 houses.

I had a thought today i could put an aerial in the shed of the house where the saorview works, i can run wire along boundry and under road via stream which is piped, i can follow up my own boundry, i could stand a pole and string it to house then, have my own machine so pole be no prob, this run would increase to 150 metres approx, i could put wire into hydradire, is this new distance too much?

Ronnie Raygun

No cable run is too long if you have a good quality signal at the aerial. The right cable type will minimise losses, & amplification can make up any shortfall.

Cable losses generally decrease with larger cable diameter (& cost) e.g. bog-standard PVC sheath "100" type cable could be €50 for 100m (signal loss ~17dB per 100m in the middle of the TV band), "125" cable €100 for 100m (~13dB loss), "165" €150 (~10dB loss). Seems to be an improvement of about 3dB for each size up, 3dB being a doubling of signal power. Presumably, direct-burial sheath would be more expensive.

Regarding a wireless link, it could be done. Unless you are willing to spend a lot it will be standard definition, not HD. There are two main frequencies for wireless video, 2.4 and 5Ghz. Wifi already uses 2.4 so probably best to use 5Ghz, although some wifi also uses 5Ghz.

You can only send one channel at a time, so you need a way of sending back remote control signals. The cheap senders in argos etc. will not give enough range.

I would suggest something like this:
http://www.aitech.com/products/media-extender-digital.htm
but you would probably need to mount both units outdoors with line of sight. Ideally you would attach a better antenna to the receiver to increase the range and reliability.

On the far end you would need a Saorview box, and then mount the transmitter beside it, to relay one channel back. I can search for more local suppliers if you want. There are some Irish suppliers selling "farmer cams" or "lambing cams" that send video back from a remote camera this way.

Quality will not be perfect, but it's actually quite good when set up correctly.

Thanks very much for that info, we had a calving camera system altered to give us the old analogue system before which worked well unfortunately the man that engineered it passed away and it gave up, i dont know what kind of a set up it is, could it be fixed and set to pick up and transmit saorview?

zg3409

The issue with calving transmitters is that they cannot send back remote control signals the opposite way. Off the shelf units have a infra red eye, which sends back a signal, normally on a different frequency, which is then received and then converted back into an infra red signal, to change the channel up and down.

Normally calf transmitters do not have this option.

Apogee

Digisender are another brand that sell long-range wireless TV extenders, along with Remote Control relay.

Maplin stock that brand if you want a look, but no doubt you could buy cheaper elsewhere on the net.

The second unit works using the mains wiring, so probably no good for connecting distant houses.

The first unit looks promising, but beware it is 2.4Ghz, the same frequency as Wifi, so you would need to keep any wifi units (access points and laptops) as far away as possible. If a 5Ghz version was available it would prove more reliable long term.

It does seem to offer what you want. It comes with 12M of cable on each end so it may be possible to mount the boxes inside and stick up the aerial outside.

Would these senders only work in 1 tele? The wifi issue is unfortunate too, you would think they would use a higher or lower value?

Apogee

AFAIK, only the top-end HD digisender supports up to 4x receivers if you look at the manual. However, if you have multiple TVs and want to watch RTE1 on one, and RTE2 on another, then wireless senders are no good. You might need to contact Digisender to verify this.

Frankly you would be far better off trying to run a length of cable from your neighbour's location to your house. Less cost, more flexibility and better all around.

Alternatively, consider a standalone mast for your own aerial on your own site - is there anyway you could test an aerial at higher elevation (attached to a crane perhaps????)?

They only send one channel of TV, so yes. You could possibly wire the output to two TVs but they would need to watch the same channel. However in your setup I assume you are getting the UK channels via a dish, so this system would only be for the Saorview channels. You also said the interference only happens from time to time depending on wind strength and direction etc so it's a quick fix rather than a complete professional setup. I assume the cost benefit factor is just "cheaper than a basic Sky sub"

Regarding the wifi and a higher or lower value, 2.4 and 5Ghz are the only options and both are used by Wifi.

I think now at this stage of the game ill sign up to sky for a year, getting close to xmas and need some viewing for the xmas, thanks to everyone who replied and their help, is there any sign of rte and tv3 becoming available on the internet, i see the bbcs and itvs and even dave on some app my friend has on his ipad.

Why not fit a TV aerial for Irish TV and Dish for Freesat?
Sky is over €260 a year minimum and 92% of what people watch on it is free.

Watching TV over the Internet is rubbish quality compared to an Aerial and uses up your data allowance very rapidly.

I cannot get saorview, my neighbour across the road can, i was wondering was there a cheap way in sending the signal across to me wireless preferred because going with a wire be awkward.

Why are you asking the same question in the thread you already started for this?

I can't believe that. You need an installer that understands aerials. I can almost believe it's true sometimes for Satellite. Hardly ever for DTT.

Anyway you can run coax up to 200m easily with suitable amplifier at aerial.

Even Saorsat + Freesat works out cheaper than Sky in a couple of years, though no TV3 or 3e, but in a couple of years they may be gone anyway.

I did read the first post.

I am not telling lies or making up stories, if you had read the first post you would have read that i had a professional tv engineer out and he is very experienced in his job and he definitely understand aerials as you put it.
I am getting a deal on sky for a year as i dont mind paying it, i will go down the route of laying a pipe next year now.
I know what saorsat is, i did say in my first post too that i would like tv3 and 3e and as you said they are not on saorsat

watty

Unless you are an expert you can't tell if the local TV installer is an expert.

I wasn't doubting your honesty. But my experience is that many people in Business have a tenuous grip on theory and can't cope with jobs that are not routine and use shoddy materials.

There is little to no inspection & regulation. Even things that have regulators it's a joke!

Indeed Watty i am not an expert TV installer, if i were an expert TV installer i would be in a position to TV/SAT work, this is why i get professionals to do jobs for me, i take some offence to your comment on questioning the expertise of the TV engineer i employed as he is a good friend of my family.
Now to address the question what is an expert?
Referencing to oxford dictionary an expert - Noun - a person who is very knowledgeable about or skilful in a particular area.
The engineer has a city and guilds qualification as a TV/SAT engineer, so he has a qualification which would deem him knowledgeable and skilful so we can deduce he is an expert, from looking at the materials he has used in jobs i have seen he uses Triax dishes, Inverto dishes, Triax and Walker receivers, now maybe some expert could cast an opinion are these reputable materials or shoddy as you say.
It would appear you have issues with people who think they are experts, i fail to see the relevance of you bringing it up, maybe you should start a thread on that and debate it, i appreciate and thanked the other people who have contributed to this thread i fail to appreciate your posts.

I find it hard to believe you can get neither Saorview or Saorsat, surely one is an option?

pegasuspub

yes it is possible to transmit a saorview signal from one house to another,however it is expensive to do as you need to change both incoming multiplexes from mullaghanish frequencies to two new frequencies and then transmit these new frequencies to your house,this prevents any interference to any house using the original frequencies,converting these multiplexes without de3grading them costs a fair bit of money and so makes it unviable for a single house,if there were a number of houses to benefit from it then the cost would be more favourable,i would advise you to explore all chances of getting a direct signal,even with a very long cable at some location on your property,
such self help transmission schemes were used in analogue days and can still work on digital provided good quality channelized gear is used.i must point out that to transmit at uhf is illegal however

If so, what makes TV3 so desirable? Go with a Saorsat/FTA combo and you'll not miss anything (other than Vinny B and some poor documentaries about travellers), TV3 itself offers little. You may even get UTV on Saorsat before long.
