Topband: Best small space antennas

[Jim Miller Waco Texas WB5OXQ]

With limited space what is the best antenna for 160?  The only room available 
is a 130X50' area.  Ground radials will be nearly impossable to put in large 
enough to be of much value.  1/4 wave antenna tried, very narrowband and 
interfeared with every receiving device in a block.  I may just be out of luck.
