Here is what I'm looking for.. I will be on very flat ground, with little obstructions (trees, buildings, etc.). I would like to know what the best setup would be. I'm thinking very high gain external antenna, very low loss coax, and a higher power wifi card for a laptop and/or or router. Please let me know what you think is the best, and where to get the equipment for the best price. I know I could spend Thousands of dollars, but I know we have more then a few baggers who have done this before. Please know, in winter, sub zero temps, blowing snow, etc. Thanks.
