Ok another question here...  there seems to be some requirements with SCC cable going from the dish to the splitter.. and also from the splitter to the PI....

 

I can get SCC from the dish to the splitter but if I put the PI with the HR 44...  does that cable have to be SCC?

Depends on how long that run is. If it is fairly short, SCC won't matter. If it is fairly long, then it could matter.

 

The whole purpose for SCC is DC voltage/current carrying capacity. If you can get the power inserter at or near the first splitter, then it won't matter after that.

Ok.  the Dish will be 50 ft to the splitter and then i have enough ports to mount the PI right at the splitter..  furthest it would be is 25-30 ft if i mounted it at the HR44

You'll be fine with copper coated in your situation.

 

Even on a much longer run where people here would say you 'must' have SCC, you can easily get away without it if you use more voltage, by replacing the PI-21 the SWM LNB typically uses with a PI-29. That should buy you hundreds of feet. Likely further than you could ever successfully send the satellite signal without amplification.

Ok cool.  I dont know if i have a 21 or 29 but if i dont have a 29 i will pick one up for S&G

With a SWM-16 install..  Is there as much of a requirement to have SCC over CCS going from the SWM to the dish?  I am looking to buy cable for my install and obviously CCS is cheaper...  the PI will be right next to the SWM16 and the distance from the dish to the SWM16 will be about 100ft

SWiM to LNB & PI to SWiM "Should Be" solid copper.

dish to swm and swm to PI should be SCC....its not as important after the SWM..hence the reason they even say you can use your existing RG59 instead of RG6

True "but for" the line(s) between the PI & SWiM.

Ok thanks.    Is there a min distance also from the PI to the SWM16?

If you use the PWR connector [with no RF] there isn't a minimum.

If you use the SWM/PWR, since it has RF, you should keep either a splitter between the two, or 15' of coax.

For 100 feet you'd "probably" be OK. CCS has 4x the resistance that SCC has, but with the tiny LNB current you lose maybe 1.5v on the 18v lines, and fraction of a volt on the lower current 13v lines. In a legacy install where receivers are providing the voltages you had to be more careful about using SCC since some receivers might have already provided low voltages to start with as the power supply aged and became weaker. A SWM16 is likely to provide more accurate voltages so you should have more room to drop a little voltage.

 

Anyway, how much are you really saving buying CCS instead of SCC? Looking at my favorite place to order stuff (summitsource.com) pricing out 500 ft of burial grade cable I see a price of difference of only $45. Less if you don't need to bury (though I assume you do)

Because f pricing when you buy a lot, the pricing isn't enough of a difference to worry abut just grab scc. I think I got 1k feet from solid signal or the perfect vision that DIRECTV uses for only 10% more than ccs.

Dont need burial..   will be install conduit..  the run outside is only 15 ft..  the bulk is tracing around my basement when i get inside.
