How tall can a 2.4GHz of antennal go on a mast for a maximum coverage. I got the card 350mW and 15dbi antennal.
Greetings!
If it is Line Of Sight, a satellite with a good antenna in geosychronous orbit would be ok.
Maybe that was a little tongue-in-cheek. You can put it too high. You really need to evaluate your required coverage with the antenna pattern and location.
It largely depends on the what type of antenna is being used (i.e. sector, directional, etc), and where the desired coverage area is. These variables will help to determine how high up the antenna needs to be mounted. As SurferTim mentioned, if you put it up too high, or don’t use the correct tilt, you may actually ‘shoot’ over (or short of) your desired target.
Yea! thanks. Am using and Omni-Directional antennal (15db) . How do i calculate my maximum converage?
A 15dBi omni will have a ‘pancake’ like radiation pattern.. e.g it will be very flat, meaning that if you mount it up high, the signal may go ‘over’ the clients you’re trying to hit (in a typical WISP PtMP setup). Also, omni’s tend to perform quite poorly in high-noise environments because they’re receiving noise from 360deg.
Assuming a low noise environment, and a client on the other end with similar power/antenna gain… you could easily do 10-15 miles LOS.
There are very few applications in which an omni of this type will perform well in a real world situation. Depending on your application, you may want to reconsider your choice of antennas, and use a few sector antennas.
OOOO Sufertim, If he was to put in up in Geosynchronysm range, I would feel bad for his clients 21,000 Miles away from earth Tisk Tisk Hope he likes latency 
Mikrotik + good signal = Good pings :-p (Way off topic, but i found it funny… dont know why) -Jordan
I realized point to point link 35 km with RB133 + R52H + panel 19 db. (perfect LOS)
On 802.11b was very stable, and CCQ was 100/100. signal strenght was -83 and troughput was 8 Mbps.
It has worked very fine for 6 mounths.
Bye - oveda
Is it possible to have 8mbps in a 11mbps band (i mean half of that)? 
thats funny…
