OTHER Is RG-6 required for fta?

[M-2 Hydra]

Im am working on my travel trailer and want to run coaxial cable for a FTA Ku dish and need to know if there is any advantage to RG-6 or if any coaxial cable will work.
Any info is appreciated

I am running coaxial in my travel trailer for a FTA Ku dish and want to know if i can use any old coaxial cable or if there is any advantage to RG-6 coaxial cable. Any info is appreciated!

Yes, it needs to be good quality RG-6. Any coax will not work as the impedance could be wrong. This will greatly attenuate the signal. Your cable needs to be 75 ohm. Also, this is just not being used solely for receiving a signal. There is also voltage being sent up the coax to power the LNB(f). There is smaller cheaper 75 ohm coax, such as RG-59. However, not at all recommended to be used for this application. Also, the smaller coax will have greater attenuation once again.
So, stick with RG-6. Decent RG-6 coax cable is not too expensive and you will save yourself a lot of headache.

I remember early on I didn't have enough cable to get from my yard to the basement window - I threw in some RG-59. Stuff was breaking up all of the time no matter how much I tried to point the dish.

A few days later I traded the small portion of 59 with RG-6. Night and day.

Do you know if any splitters or those combine one cable to another cable adapter will obstruct the signal at all because i want to run it to two places in my trailer and dont want to weaken my signal if i can help it. And does 75 ohm mean the resistance between the inner copper core to the outside ground or just from one end to another? I was a bit confused on that part

75 ohms is the reactance (not resistance) from the inner core to the outer shield at RF frequency.

The DC resistance between the core and outer shield is near infinite.

Just get RG6 and you will be good to go. I got mine in bulk 500 foot rolls at Home Depot.

There are no splitters like you are thinking of. Each receiver location will need a separate cable connection to the LNB(F) on the dish.
