Having only one cable is a real bonus. It's unlikely that 25' is the actual limit of service but if it were, moving to RG6 quad shield or RG11 would likely allow you to place the antenna at a much farther distance.
What I post is my 2 cents and nothing more. Please don't read anything into my post that's not there. If you disagree, that's OK.
Can't we all just get along?
