I have a sponsor for my team that helped my set up Kilowattnet at the UTC Regional. They provided me with antennas to provide good coverage to the entire event. I had some 15dBi Panel antennas and some 12dBi Omnidirectionals. I hooked them to some D-Link Access Points and they blasted the area. If you guys need any high-gain equipment, I will be willing to talk to my sponsor and see if I could you guys some equipment on loan. I am willing to help you guys with equipment and administration.
Check out my Sponsor's catalog,

I look forward to helping you guys!
