    Take a SO-239 chassis mount female coaxial connector and solder four lengths of coat hanger wire to the base after crimping them to the empty screw holes. Take a fifth piece of coat hanger wire and solder it to the center conductor. This makes a simple groundplane. Plug a PL-259 male coax connector into this and the other end ot your rig and you're all set.

    The lengths of the coat hanger wires should be 5/8 or 1/4 wavelengths of the operating frequency. Mount the antenna on a broom handle and stick it on the roof.

    This is the first antenna I ever had.  Made it exactly as you stated and it worked great.  Used it for simplex and packet.

    Figured out the length using the formula L=234/f
    However, getting a coat hanger to solider to the so 239 is interesting.. did get it .. only the center of the so 239 broke off still enough there if I can get a connect or over it and couple it to the coat hanger element.

    i think i will place a piece of rubber tubing a couple inches long over the center end of the so 239 for reninforcement .. any body have any other thoughts on this ?

    this is the first antenna i have ever built hope it works. I will be trying to key a repeater that is about 10 miles from me as well as simplex ..

    on long wire antennas: see my article in the september 2001 cq magazine on a simple 160 meter inverted-v antenna which can easily be turned into a sloper v-beam for 40 through 10 meters.  kd6gn
