Digital/Analog Coax
Just switched from a MH. to a Travel Trailer. Using a Wineguard Playmaker. Coax is probably 5-6 years old. 2-25' lengths joined together with a adapter. Picture is not clear. Is there a difference ...

FIrst, since you are using SAT TV you should have been using good RG-6 all along, Oh the RV makers say "RG_59 won't matter for that short run) but on the average RG-58 has FOUR TIMES the loss of RG-6.. ---snip---
That's because RG-58 is 50ohm.. :)
Opps that was a typo (I said 59 in the part you quoted, but typoed in the other part) I meant to say 59 has, on the average, about 4 times the loss of six.
NOTE: 58 does too but. as you said, different impeadence.
OH, here is a shocker,, Did you know if you have the proper length of cable (An exact half wave or multiple thereof) the cable impedance basically does not matter? Of course odds you will hit a half wave exactly without a lab to measure the length of cable electronically.. Zero or darn close to it.
