There is a good ham radio supply house next to the post office at 80th 
and Conser in Overland Park.  The ham radio boys play with everything 
from ULF to light.  While you are there, pick up a copy of the ARRL 
handbook.  It is the most important and useful book I have ever owned.

It will have plans and diagrams to make something that will work in your 
application, plus the proper formulas so you get the right antenna size 
for the exact wavelength you need, and guidance on the proper coax or 
wave guide to use for that frequency range.

I used plans out of the manual one time to make a really neat 
omni-directional 1/4 wave ground plane antenna out of a panel mount 
female coax connector by soldering the correct length lead into the 
center connector, and off of the four holes used for mounting the 
connector to the cabinet.  Connect the coax from your radio, fasten to a 
non-conducting pole and TA-DAAAA . . . .
