I would make it a bit longer then 3 quaters and then bring to resonance with 
the serial capacitor. \that will make the impeadance higher and improve 
efficiency of the antenna somewhat. MMANA is a good tool for modeling and 
understanding what is going on.

    Roy, K6XK, is right. The only function of the horizontal wire is to 
bring the antenna to resonance. The antenna is basically a short vertical 
radiator loaded by the horizontal wire, and the minimum total wire length 
needed to bring it to resonance is a quarter wavelength. The next length 
that works is three-quarter wavelength, not full wavelength.

    Keep it simple!
