I used to know but have forgotten.
What is the longest cable run for a Diknet receiver to be specific on B3V 3100.
I will be using good quality RG6. I know they recommend about 100' but I know you can go longer. Think I could use 250' and still get both polarities?
For about $20.00 you purchase an inline booster. There are powered and self powered using the receiver power to the LNB.
...and they suck.Quote:

Dynas,
The problem is voltage drop in long runs not signal.
I tried an online voltage calculator at 250' found here:
250' should be OK according to it, considering an LNB only consumes about 250mAHTML Code:https://videos.cctvcamerapros.com/voltage-drop-calculator
And what does the voltage drop result in?If you're talking legacy lnb, good luck with 250 feet.Quote:

but alot less than RG6
I think if you use a Dish Pro LNB you can go 200 feet.
Your correct Jedi, with DP+ LNB's and Dish/BEV OEM receivers you can go up to 200 feet, I have gone as far as 350 feet by putting a DP44 switch at mid point of the run. (worked fine)Quote:

Also legacy systems (systems that use a DC voltage to switch between H and V transponders) are limited to about 100 feet, (a bit more with better high quality coax) anymore and the DC voltage drop at the LNB may affect the DC voltage switching in the LNB and you could miss out on some transponders.(+13 volts DC= Vertical, +18 = Horizontal)
In all, RG-6 quad coax rated out to 3 GHz with a pure copper center conductor is the best way to setup any satellite system.
There are cheaper coaxes out there but some are only good out to 1 GHz, these types are for cable TV or off air TV, not too good for the newer type DP+ LNB's that can go out to 2.2 GHz on the high band.
And some use a copper plated steel center conductor, this type is OK but the DC voltage drop is higher then the coax with a pure copper center core.
So if having signal problems then check you coax, it should be swept to 2.5 GHz or rated out to 3 GHz if using the newer style DP+ (DPP) type LNB's.
