Re: 15 Mile - NLOS - Suggestions?
well, at 15 miles, maybe with a telescope.  Seriously, I'm just asking because I don't know. I do know that the earth starts curving at something like six miles so you have to start raising it on both ends to beat that plus you've already got pine tress out the wazoo (highly technical wisp term i understand) that you've got to top also.
I guess I need to find some of that fancy 3d topo software to look at it on the pc first. |

| Well at that distance, your probably only going to be able to just do trial and error. Which would involve climbing a tower(s) and placing radios and antennas. As long as at 100Ft on one or both sides your not going through trees it's possible

Crockett, TX | so, you're saying 2.4ghz might work, given that the trees can be overlooked?
Is there any drawback to placing the first node at 200 or 250 ft? |

The only drawback is that the link will go out in the freezing or wind driven rain and you have to climb up there and fix it, but that is how my links are here in Jville. I have a program called Micropath. It will do the link analysis' that you will need. Shoot me a message and we can discuss it and see if we can make it work for you. |

| Jacksonville huh? I'm in Crockett so you definitely know what I'm talking about. I'll pull up google earth and get strong "guess-timates" of the gps coordinates to let you guys play with. The rural population here is so sparse that it's hard to know which direction to point your antenna. I really need a map showing me where everybody lives. Any good products for something like that? |

Jacksonville, TX | Besides beating the streets, I don't know. You may be well off the head in the direction of Alto and Wells. |

If you are in the Texas Woods, to get a 15 mile shot point to point you'd be best off to start with 900 mhz canopy with a 12 db yagi. You will have to be above the tree tops, and that's at both ends. if you can get up around 300' on the base end the receiver end would only have to be around 50' or so to hit it. if you have your co-ordinates send them to me and I'll email you a comstudy shot so you can see what your terrain is. |
