If your listening is concentrated in just that one band, you may wish to consider a dedicated antena, such as a dipole. Running it away from the house (such as between two trees) and feeding with coax and a balun should reduce pickup of local noise sources from inside the house. A folded dipole (made with 300 ohm twin lead) may offer even lower local QRM pickup, but you'll want to use a 4:1 balun in that case.
