Hi,

I've recently bought a sony bravia with freeview and got an UHF aerial installed a few days ago.
The new tv is upstairs while the tv with sky is downstairs. Before getting the new tv i had a video sender box downstairs transmitting a uhf sky signal (i think).

So with the rabbit ears upstairs i could tune to find whatever channel was on sky downstairs this has worked fine for quite some time.
However with the UHF aerial on the roof, the signal from the video sender is either vhf or too weak to reach the aerial.

Would getting one of these work? http://www.dse.co.nz/dse.shop/4b9850c901a91cdc2740c0a87f3b06e7/Product/View/L0200

Cheers

Yes it will work but I'd advise against getting a 2.4GHz model. I bought one once and the interference is too great. everything from the microwave, the cordless phone, garage door opener uses 2.4GHz.

what I did was return the unit and paid extra for a 5.8GHz model (from Jaycar)

It sends your remote control signal too which is good but it is only SD... It has directional antennae which are useful and the signal goes through walls no prb but does break up if someone walks through the beam (but only while they walk through it)

I only have a big old CRT in my bedroom so its good for that but if you have a 720 or 1080 TV Id suggest an HD sender.

Last I asked the UHF senders were not legal when we looked at importing some of them. FM transmitters have a specific GURL to cover them, nothing like that exists for UHF, so now you are not using it you are not breaking the law ;)

Forget the 2.4GHz ones, 5.8 is becoming just as bad as people are driven to go to it so they can get something that works, but there are more channels so its a little better.

But they will only do composite video, which looks rather crap when you are used to HD.

IMO run cables for HD, anything else is just a comprimise.

Yeah the current video sender was probably bought in the early 2000's can't remember where i got it. So i'm looking at getting a 5.8ghz transmitter and 2 receivers and if i understand this right, the IR extender means i can use the sky remote upstairs by pointing it at the av sender?

Not sure if it's still an issue but I found the IR remote sender aspect of an AV sender I had once worked for everything apart from SKY. There was a known issue that the type of signal the SKY box used was not easy for the IR senders to work with.

Anyway, I'd have to agree with richms comments above. The AV senders are close on rubbish in my experience but it might work for you. Just seriously make sure you can return if/when you need to. Running some cables (even straight rca composite+audio) will give you the same and probably better results.

These AV senders are rubbish. My neighbour has one and it changes our channel as well as his. Annoying when watching family movie with the kids and he decides to go porn channel surfing! We have to go along for the ride.

There are ones that have codes for the IR repeater part of them to stop that happening.

You in apartments? THats the only way I can see that the IR control would reach between households.

Not in apartments, two separate houses. Approx. 20 metres from his sender to our Mysky box. Don't these things work on RF?

Yes, but 20m between houses is quite an achievement for them. The digitors from DSE have the code selector on them. I dont know how it works exactly, but it doesnt change teh freq of them, as I was hoping to cascade a couple to get the range I needed to go from upstairs to downstairs and then out to the shed.

Also, it only started happening when he got SkyHDi. He had the sender before then and it didn't affect us.

Should be good till dual band accesspoints become dirt cheap, then we will see a repeat of the 2.4GHz fiasco. I am suprised there isnt more stuff moving to it. I think the variances of the bands around the globe are stopping it to a degree.

Me, I am using my not very legal 1.2GHz camera's sender to get video out to the shed. Noone using that since there is stuff all gear for it around. :)

I have a 2.4Ghz video sender that I got from DSE in the early 2000s (not the model they currently sell - a Gigaair 2020 from memory). The signal is only composite, and there is some degradation compared to what I would get if I ran a cable. It doesn't get used that often, but is perfect for late night rugby matches in the middle of winter - I can watch it cozy in my bed rather than going downstairs at 2am. While the picture degradation is noticible, it remains watchable. At only $69, and given that you can return it if it doesn't work adequately, there isn't much to lose from chancing the purchase.
