Help needed building an antenna

Im not to ham radio, been licensed since 2005, but my lack of antenna building is not great, My girlfriend and I build a random wire this past weekend, and the height is ok, i think 10-15 feet, with a pully system, No balum at all. Any helping building a 160-6 multi band diople. Any antenna that would work great, with limit space in the city of fond du lac. Thanks for looking and hope i can get some helping understand and helping of building a great antenna.
