Topband: Common mode current and QRN on 160m

I have built up a simple switch box to use on 160m which reduces the QRN a bit on the band so that I can see the weaker stations out there. My noise level is usually s9 and am going to try a 1:1 current balun at the antenna feed point which is a 45mm dia 6m high pole bottom fed. I have about 15 - 20 radials in to fit my garden 30ft x 30ft, but neeed to improve my reception and the QRN. Any suggestions on how to cut the local "smog" other than what I am trying. The pole is mounted abot 3ft away from the garden corner ( not ideal ), but it has to be there. I was thinking about another antenna for receive such as a pendant or such like mounted above the roof and use a small rotator with preamp, that should reduce the QRN even further
