Advice Needed Length of LNB arm

[daro2096]

Am slightly bored and want to know the answer to this question:

How long is the LNB arm on a 85cm dish roughly? Need to know to know how much 4 lnb cable to buy for going from lnb to diseqc switches.

Need to know to know how much 4 lnb cable to buy for going from lnb to diseqc switches.

It depends where you intend to put Diseqc switch. I think that 5 meters of cable would be enough to do cabling around antenna.

 

[daro2096]

From LNB to back of dish. There would be 4 quad LNBs using all 4 outputs on each.

 

[RimaNTSS]

There would be 4 quad LNBs using all 4 outputs on each.

Than 4 x 5m = 20m
Plus, do not forget about 4 cables from dish to your 4 receivers.

 

[daro2096]

That seems a lot.

 

[RimaNTSS]

Yes, but there no wireless solutions to get system work.

 

[daro2096]

True. So the length of the LNB arm on a 85cm dish is 5 metres long? The cable I intend to buy(maybes) has 4 cables inside a bigger cable.

 

[RimaNTSS]

So the length of the LNB arm on a 85cm dish is 5 metres long?

Did I say so? 5 metres is for 4 runs of cable. LNB arm is less than a metre. You better buy more cable and have some left over after installation instead of going to shop to buy another 2,3 metres

I just buy cable (WF100) on 100m reels then I stock up again when they start getting low...

4 Quad output LNB's on one dish, that's a lot of connections to do, a lot of coax hanging in the air and more things to go wrong.

Just use 4 cables to 4 single output LNB's and use a multi switch, you can get 4x4 multi switches, (or an 8x4 if you have the old legacy style LNB's) then you only have the 4 single coaxes coming in from the LNB's (or 8 depending on the LNB used) and 4 single coaxes running out to your receivers.

One switch, less coax, less connectors equals less things to go wrong.

I want to be able to record one channel and watch another. Maybes another from another satellite.

 

[RimaNTSS]

To record one and watch another channel not necessary to install Quad LNBs, it could be easily done with Twin LNBs.

 

[daro2096]

True but if they were quads I could record 4 channels plus.

 

[RimaNTSS]

But in the beginning you were talking about one channel watching and another one recording
By using quads, you certainly can do simultaneous recording of 4 different channel on 4 different receivers or one receiver with 4 tuners.

Motorize the dish

Motorize the dish

But then I couldn't record from two or more satellites.

 

[RimaNTSS]

BTW, OCTO LNBs also available. With those possible to do 8 simultaneous recordings/watchings

As you have "" No setup at present ""
You have to get a basic setup first to build on.

I have just moved house. That is why I have no setup at present.
