New installation, long cable runs!!!!!

Randyleprechaun

Some advice required on the following if anyone would like to give any input.
Thanks

Dwelling house with no existing satellite setup. Line of heavy, tall trees to south and east of dwelling. No signal can be received from any part of house, even using poles etc etc.

Signal can be received from front/side lawn of house. Cable runs from dish to receivers will be up to and very near 100M. Only 2no receivers being installed at present and unsure how many that may become in future, 4no I'd say will be max?????????

Cables to be ran in ducts for as much of length as possible.

Just wondering,

1. Is RG6 good enough or would something else be required over that run length. Would amplifiers or anything be required
2. Would it be better to run 4no cables and use quattro LNB and multiswitch or run 8no and use OCTO LNB, just in case more than 4no receivers ever required or recording facility ever required.


If anyone has any other input, feel free!!!!

Thanks

It depends entirely on your location, the satellite transmission(s) that you desire and the dish size. To drive the signal through 100m of WF100 cable, you'd be well advised to go up a dish size (e.g. from 80cm to 1m).

If by "RG6" you are referring to cheap cable with aluminium foil then I'd advise against it. Sky stopped using it because it doesn't last many years outdoors and because its signal attenuation is somewhat higher than that of WF100.

If a larger dish is out of the question, you'll have to try an equalised gain slope LNB amplifier in each cable, about 40m from the LNB. Waterproof conduit would be a good idea - especially if you decide to use RG6.

Before doing anything fancy, simply lie the cable along the ground and get a signal strength reading. If it's just marginal then WF125 cable will improve it by a couple of dB, without the need for anything else.

hi i can give you good honest advice on this . if you want to do it right then i would use a 80cm dish and i good quality inverto lnb. ---quattro lnb and a triax multiswitch and a triax satellite headend amplifier. this will work fine on a 100mtr cable run no problem . can you put the headend amp in the middle off the cable runs ? the headend amp can be adjusted /balanced very easy to setup -- i am only saying to use triax but you can use other brands if you want ---vision ---antiference ---televes --- etc all vary in price . multiswitch can allow 4---8---16--- 32---50--- connections should you need that many. also i would use good quality copper on copper foam filled RG6 or ct100 or mf100 cable you can buy this in 250 mtr drums. put a scaffold type pole in the ground and concrete it in go about three feet by three feet and it will never move . if you only need four feeds the again use a 80 cm dish and a good quality quad lnb four cable runs and you can by a single satellite in line amplifier for each cable run . satellite signals on a 100mtr cable run will drop off on v/h high bands and v/h low bands but you will find that the signal strength will be ok the signal quality will get low if you can put two 20 mm white conduits into the ground and feed your cable up these to your home this will protect the cable . -- what type off satellite receiver do you want to use freesat type? or sky plus hd ?
any problems and i can help --- professional installer in belfast ---

Your post is very confused. I don't see why conduits should affect the signal quality.

CT100 hasn't been manufactured since 2005.
"RG6" as sold here is always air-spaced dielectric, not foam.

An equalised gain slope amplifier *might* be required in each cable IF the highest frequency multiplexes are badly attenuated but I'd recommend testing without amplifiers, before spending extra money.

Hi
If you can afford it look a Fiber-optic setup, no signal loss issues and no need for external amps ect. You will need two cables to the lnb a fiber cable and run ct100 as your power cable, both could be run in half inch heavy duty hydrodare you can then add as many receivers as you wish in the house.

Good answer - except that CT100 hasn't been manufactured since 2005 and is no longer available. Look for WF100 or TX100.
