Many companies sell a 24db gain antenna for 2.4 ghz. I bought several from a florida company about 5 years ago for $75 each. They worked great and we never had a noise problem with the vhf or uhf repeaters at the site, although we left all of the transmitters on the ground and ran coax to the dishes at 150 ft. Links where 1-13 miles in varios directions with great signal. Amazing ERP with 1 watt and 24 db gain

The Internet company guy was ready to say it just couldn't be done for his location and distance. He asked the guy to come back the next day for one more try. In the mean time, he hauled an 8 ft satellite TV dish up the ham tower. pointed it in the right direction and then hung the internet link antenna at the feed point. next day the internet tech took one look and said it will never work because you have the link antenna pointed the wrong way. My friend said humor me and give it a shot. Much to the techs amazement the signal was plenty strong and he was able to finish setting up the internet connection. So finally getting to the point, find a surplus satellite dish and maybe you can get enough signal at a lower height to get enough separation between the 2.4 GHz system and the repeater.
