Sky coming to install *correct set up??*

torrestorres

Sky are coming back to install my Sky box again as it was not installed as I asked 1st time.

Bit complicated this so please bear with me , my home is prewired for multi-room AV and I have ordered a Russound Cav6.6 unit which is in transit to me as we speak.

The installer last time just installed sky as normal as he didn't know what requirements I had requested off the sky agent (was agreed) so he is coming back to change it around for me (nice guy).

I have 4 coax cables in the attic which he will have to connect to the Satelitte Dish, these 4 cables run to the central hub under the stairs (Where my sky box will be placed when the Russound cav6.6 unit arrives), but for the moment im going to be leaving my sky box where it is (Living Room) so we can still watch tv.

So what I've done to prepare for sky installer coming is this.

1. Connected coax plugs on the 4 Coax Cables coming from the attic to under the stairs (Central Hub)
2. The Coax cables running from understairs (central Hub) to Living room (tv point) I've connected coax plugs also.
3. I've connect both cables (going from tv point to central hub and central hub to attic) with a coax joiner.

So what I'm asking is will the sky guy still be able to send the sky signal from dish, down these 4 coax cables (in Attic), through the coax connectors and to the TV point in living room?
Thanks for bearing with me, I just want to ensure all is ok for when he arrives

Well if he is an independant installer he may well do that, but from what ive heard is that sky (Finlays etc) will only install the Sky dish and run their own cable down into the living room (Apparently its all helath and safety)

This is the thing all the cables are there for him, he needs to run nothing just connect the 4 cables in the attic to the dish, i spoke with him on the phone, seemed a nice guy and said it woudn't be a problem.

I've connected the cables attic/understairs to understairs/TV pint with coax connectors, but i don't want it to be a wasted trip for him if i've done it incorrectly.

I just want to ensure that its ok to connect the coax cables like i did so we can continue to watch tv until the russound unit arrives, a week without tv the kids will go crazy

What sort of coax and plugs?

i put these on both ends of coax




and connected them with one like this only in black.

But how are the cables from the attic (inside) going to be connected to the dish (outside)? If you've left enough slack and are happy for them to drill a hole through the facias/soffits then that's fine.

Wrong connectors. Should have used these (f-connectors and barrell):

yeah they are in the attic all right so he just needs to come in through a gap between the attic and facia/soffit.

Are you 100% sure?? i went into a electrical shop and they guy told me there were what i needed, although he didn't seem to know his stuff to much.

Are the F connectors not use to connect coax to the actual sky box?? not used for joining 2 coax cables together

Sorry i should have mentioned at the end of actual TV point i didn't put any connection, so the sky guy could put his own connection (F Connector), i just joined the 2 coax together under the stairs to continue the flow from attic to TV point.

Yes, they are for joining cables too. I used them for FM Radio and TV as the other kind are very poor. F-connectors are the only reliable domestic method of connecting coax, especially for satellite.

The cable carries 22kHz (near audio frequency) and DC to power the receiver at Dish (LNB) which is also switched by change from approx 13V and 18V.

I ONLY use the other sort for back of radio or TV.

Did you get proper cable?

Especially read http://www.wrightsaerials.tv/articles/coax-cable-quality.shtml

The most important aspect is actually interference (cable loss is secondary). The Satellite signal is very strong as it's amplified to a high level at the LNB (block on Dish arm). Without proper screening it interferes with many other things. Also many things such as DECT phone, GSM phone, 3G Phone, Security systems and other things including motors will cause drop out, pixellation and freezing of particular channels due to interference getting into cable.

But the ones i used can also work to??

The cable type in my house is the cable C.

watty

No, those connectors are very erratic for power and low frequencies (22kHz) and high frequencies of Satellite IF (950MHz to 2100MHz). They are not even very good for TV.

You need F-Connectors.

Note there are wide range of "cable C" and Sky won't use even the best of them. Only Cable A and B is suitable for Satellite, especially if there are joins.

TX100, CT100, PF100 etc real satellite grade coax. Sorry.

Oh dear God i could be in trouble so , im gonna call the installer this evening and see what he thinks, i think i'll also pop back into the electrical wholesalers and pick up these F Connectors.

The joining of the cables is only temperary as when my Russound cav comes the coax will be connecting into the Sky Box direct under the stairs and then from the sky box to the Russound cav6.6 unit to distribute to the rooms.

Cheers for you help and time in replying mate

Installers can be experts.

But most Sky Installers know much less than you. They are just trained to bolt dish, align it and run cables. Most are not even technicians.

Unless it's an independent specialist company it's pointless to ask his opinion.

Sky doesn't pay enough per install for qualified Riggers, Technicians or Engineers.

Lol a bit harsh but sadly true...

The installer should have all the correct connections, that he should use.

you would be surprised i used to work for a large sky installation company in ireland, and the guys were given 2 joiners a week yes you read correct... i used to buy my own in bulk as it simply made my job so much more easier and saved time

Op, make sure you throw the installer a few extra yoyos for doing that additional work. Otherwise Sky may hit you with a non-standard installation fee.

I started out with one of the larger Sky installation company's, who eventually stopped supplying us with co-ax connectors and back to back connections to prevent employees from doing extra rooms/nixers on the side.
I started bulk buying my own too.
