You're definatly looking at at least 100Ft towers on each end. This was done with out any tree data because RM doesn't do trees well on 100%. No matter what height you have the units at..

I believe this is with 900Mhz 13dBi yagi's at .5 watts which is way over what you can use but I forgot to change it. Nope it's .2, and just under 4 watts EIRP

If you kindly locate the potential tower site, we can easily do Radio Mobile propagation analysis to see what kind of coverage you will get using different tower heights and different foliage assumptions.]]> http://www.dslreports.com/forum/remark,16758338 Tue, 22 Aug 2006 17:13:56 EDT http://www.dslreports.com/forum/remark,16758051 EZ Net La : 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.]]> http://www.dslreports.com/forum/remark,16758051 Tue, 22 Aug 2006 16:33:50 EDT http://www.dslreports.com/forum/remark,16755654 slipstream1 : Besides beating the streets, I don't know.

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?]]> http://www.dslreports.com/forum/remark,16755502 Tue, 22 Aug 2006 09:46:11 EDT http://www.dslreports.com/forum/remark,16755458 slipstream1 : 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.]]> http://www.dslreports.com/forum/remark,16755458 Tue, 22 Aug 2006 09:36:16 EDT http://www.dslreports.com/forum/remark,16755270 harmetp : A 15 mile piece of cat 5 wire works in most of these cases, but this is a wireless forum so we won't go their :D.

Anyway, for most 2.4 and 5.8 gear you really need line of sight, 900 will penetrate more, but it seems (like cell phones in rural areas) that it will penetrate that last wall in a house, but not a forest of trees before the house.

If you have the $, get high enough to get line of sight, otherwise it will be a troublesome link. I have a couple of 10mile links that work great, but their is nothing in the way. When I was setting it up even some dead tree limbs killed the signal.

Hope this helps,

If you don't get high enough on both ends of the link, you can have Fresnel zone problems with the earth's curvature and the trees.

If you don't know what Radio Mobile is or how to use it, you could post the coordinates on here and someone will probably take the time to calculate it for you.]]> http://www.dslreports.com/forum/remark,16755018 Tue, 22 Aug 2006 07:12:04 EDT http://www.dslreports.com/forum/remark,16754232 manshack_one : 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?]]> http://www.dslreports.com/forum/remark,16754232 Tue, 22 Aug 2006 00:51:47 EDT http://www.dslreports.com/forum/remark,16754224 rawgerz : 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

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.]]> http://www.dslreports.com/forum/remark,16754205 Tue, 22 Aug 2006 00:45:36 EDT http://www.dslreports.com/forum/remark,16754187 rawgerz : Your saying, that 100Ft you cannot see the location?
If you can see 95% of the way 2.4 should work. 900 would be more suited at short range maybe 2 miles with more obstructions, like at the most 1/2 of woods, something like that.

The base antenna I can probably get 100 ft in the air. I'll either go rooftop or treetop (if necessary) to get the height required on the other end. It's wooded (heavily in some spots. Will 900mhz equipment be required? What kind of equipment (and at what ballpark price) can this be done with?
