cable joining

[theblueirish]

happy new year to you all,

i have a problem installing a dish in my mates house, we cant change the cable going down the conduit, its brown 50ohm cable and wont budge so we cant pull it through. it is also cut short where it comes out behind the tv, so another join has to go in there.

what is the best solution for this, i have tried running 75 ohm coax and joining it using a barrel connector, i am getting sever loss in this and some transponders flicker from 74% down to 30%.

will the signal carry if i use 50olm cable and join it?

any help greatly appreciated,

use proper satellite cable is the best action , preferably with no joins at all

f connector barrels will join the cables , but if the cable is cr@p then no amount of barrels or soldering can change that

my advice , find a way to get proper sat coax like ct100 or ct125 from the lnb to the receiver , nothing else comes close

happy new year m8

thanks for the reply,
unfortunately we have no choice the cable wont budge and i cant get down the wall i agree with you 100% about the joins but its a bad situation.

if its a cavity wall , go down that like I did

75ohmc to 50 ohms to 75 ohms, loads of missmatches and signal loss.
I suspect that the 50ohm brown cable is single screened so not ideal for carrying sat signals.

even brown tv coax should be 73 ohm
and not 50 ohm
