It is just a 10 acre farm, but it is also a teaching school so they have more IT needs than they might otherwise.
They just ran a little less than 300ft of direct bury Cat6 cable which terminates at a pole that has 120v service available. He is going to have an enclosure built and his thought was to just put a consumer grade access point in it, and the 2 campers (Both are older with that thin metal shell) which are about 75 and 125 feet away.
My thought was that with putting the AP in an enclosure, and then trying to gain access within the campers, signal could be really hurt.
I thought a quick way to improve signal would be to use an AP with an Omni mounted outside the enclosure. I've personally mounted outdoor rated gear such as Cisco Aironet, and I've definitely installed my fair share of consumer wireless devices, but I've never tried to something like this on a budget.
Any thoughts? Ideally I'm looking for a specific AP and compatible antenna and overall just a confirmation of my recommendation.
