if its a decent brand of cable with good connectors its probably not worth
shortening it. you will reduce the loss by about 50%, but the loss is
probably low enough that it doesn't matter anyway.

At the second house in the country,my TV antenna,which is in the attic, is
working fairly well but I wonder if shortening the cable from the present
50
feet to the 20 feet I really need will help.The present cable has very
professional fittings at each end since it was sold as a unit .
I have a crimper and fittings
