da' grades uh cable and lengths
Yes, the prior poster is very right at what he is saying. It is both signal, strength, voltages, and the ground, or outer jacket of steel multi-stranding and foil; or how much the ground protects external signal ingress, normally a percentage like 70 or better; that determines how good the cable is.
Each application, or use, determines what wire you should use. If I run a motor on a 33" dish, I do not run over 80 feet, because the motor draws from the 18/14 vdc LNBf supply, and when you go longer, it will be problematic as power supplys these days just are not as good as they used to be, and this is what sends the voltages up the wire, and then the wire sends back, or even receives signals in both directions, multiplicity of use it is...
Cable, whether cheap or expensive, has it's problems when running long distances, or when you bury it in the ground and there sits the home of the gopher.
The rule of thumb I always use: The less I need to use, the better. Design the install of your dish to use the least cable you can, setting up the dish mounting as close to the receiver as possible, and as asteticly pleasing as you can to you and your family. Higher is not better, farther is not better, only more challenging to the receiver also, that is, it tests the power supply, the ps chips, the regulators, the capacitors, harder and wears them out faster too...
When I must go long, I protect it. And when you have to go overhead, make it the stronger type (like the one with a ground wire extra [used to be called messenger cable]), when you run it inside the attic, use Plenum (so it will not gas you if fire hits); copper wire is better, but very expensive comparatively, if you can afford it, get it, but protect it well, cause it will fail just like any cabling.
Cable is where problems happen, and normally it is because of mother nature or us; ingressions like rain or water entering a small hole or the connector, in the cable, improper installation of wiring will cause it to break, or for water to enter a device or the home. Do not use a basic stapler, that curves around the cable tight. These actually, when you "hit" a cable, ground out the ground, causing all sorts of probs (like a DISEq not to work), so use insulated by plastic staples or holders "that cradle your cable like a newborn baby" of the type needed, to "protect" your cable from installation woahs...
May the force be with you!
By the way, I absolutely loved the first iPro 2000 I used first and installed another for someone else. First of all, the remote is ivory and deep black, very stylish; and the reciever had autoscan or "magicscan auto switch setup and deploy" for all satellites that were hooked to it, no matter what kind of switch! A first, and I cannot quite remem, oh ya, it was made to be programmed over the internet, or network setup too, another first of its kind; very innovative...just what it is made for, you'll have to find out that from someone else, because it is not tolerated here...
