Hi All,

I'm currently considering getting the Humax Freesat HDR box for the bedroom. We currently have Sky+ in the living room, so already have the dish in place with a quad LNB in place (two taken for Sky+ two free).

I would like to check that I am correct in a few things before definitely going down this root.

Am I right in thinking that I will need to run two Coax cables (with screw on f connectors at each end), and if so, where can I get some "dual coax" cable, I've tried search term but it's not what I'm after, the sky cable is two coax joined together, this would look more elegant.

Also, what's the thing that needs to go on the outside of the house, that goes around the cable to prevent the rain/weather from getting in?

I think that's it for now, any help/advice, would be much appreciated.

It's called 'shotgun coax' http://reviews.ebay.co.uk/Which-Coax...00000004566372

and you could use these http://www.screwfix.com/search.do;js...hbutton=submit

Cheers Guys,

I'll make sure to have a look at them once I've decided what to do.

Thanks.

There's also nothing to stop you running two single cables side by side.

I know but if's going to be run up the outside of the wall at the front of the house, I think it'd look tidier (unless is turns out to be stupidly more expensive for Shotgun coax).

Just need to hope that someone I know will have drill and drill bit suitable to go through the wall! Luckily I know someone with a wire/metal detector and also know where all the cabling runs in our house anyway, after the Sky engineer drilled through the power cable to our upstairs lights last year!

Of course there's also the problem that we live in a town house (i.e. 3 floors) so the bedroom is 3 floors up! But I'm sure that's nothing a little stupidity can't over come! lol (I am only joking, I wouldn't do anything stupid to get a cable up that high!)

I think the shotgun twin co-ax is best avoided if possible, see this thread:

Only the thin stuff, you can buy standard sized shotgun cable - but it's obviously not cheap - and I'm not quite sure how you drill a figure eight hole through the wall?

I'm sure the shotgun coax from satcure would be of great quality.

When the Sky man put in the shotgun coax that's currently connected to my dish, he just drilled a hole big enough to stick it through and put some plasticky thing on the outside to stop the rain getting in.

So far my two main concerns are attaching and protected the cable to the wall outside (and attaching it 3 floors up), and then drilling through the wall.

Unless the run was massive I would expect the losses on the stuff sky use is immaterial.

Otherwise we would have a lot of unhappy people out there with poor quality pictures to back this comment up. I would expect it would be more poor quality installation which would be the main culprit.

The main point a cable will make a loss is at any joint / connection to LNB and Saterlitte equipment.

People need to look at the run length and decide from there what are acceptable losses. The longer the run the higher quality the cable needed. But most standard installations will be fine.

Its a while since I have dealt with attentuation losses in cable I will attempt to put my view with the details below.

I take it the main carrier frequencys go from basically 950 TO 2150 MHZ (LNB feeds out) . Below are some spec's.

So basically sky standard cable on a 10m run will loose 3 to nearly 5dBs depending on frequency. How many people have 10 meters of cable ?

To be honest this aint going to hurt. Ok its twice the amount as WF100 but cost against cable run length per losses its agreable. But the longer the run you need to look at the better cable.

Attenuation
Frequency WF100 WF65/CT63 (SKY)
860MHz 18.3 dB/100m 30.0 dB/100m
1000MHz 19.9 dB/100m 32.5 dB/100m
1350MHz 23.4 dB/100m 37.3 dB/100m
1750MHz 27.0 dB/100m 43.2 dB/100m
2150MHz 30.3 dB/100m 48.4 dB/100m
