Take you rf calculator out an put in 50mw into a 2.2 dbi omni, then put a 26dbi dish 7 miles away with perfect line of sight. Okay, click the 'calculate' button. Got any signal left? If you don't have a good antenna and output signal on BOTH ends, you'll get nada. That was the point. That was the answer to the original question. All this stuff about 70 mile links is fine, but it's irrelevant.
Can it be done with a dish like this? http://www.seti.org/image/dish_delivery.jpg Ask the cia, they probably know. Ken Jason Slagle wrote:

Try again and thank you for playing. Links over miles happen every day. I have done on several occasions a 9 mile link over lake erie - one end is a 13.5db yagi on a 100mw card, the other end is a 12db patch or omni on a 500mw output. Works just fine.. Plenty of WISP's will disagree with your "1/2 mile" theory - they seem to deploy 2.4ghz 15 miles with 22db grids. 7 miles away if the antenna is in line of site with a strong receive gain is going to be fairly easy.
