Hostap plus omni antenna

Hi the list,

Mix two kinds of antennas with a splitter :
- one kind for long range as a colinear omni with 12 dBi,
- one kind for local area as some patches, but not omni, or split again with 4 or 6 patches for omni coverage as cellular phones
repeaters;

The power will be splitted through all the antennas, reducing surely the long range effect, but...

Or use only one omni antenna with electrical downtilt attack angle from 7 to 3? under the horizon line with a maximum of dBi (12 dBi
is a good compromise if not too hight).

In all cases, antenna efficiency (in dBi) is always the first point with the vertical beamwidth, the second is the cable and
connector losses, before choosing any wireless card or increasing the output power to incredible level (and dirty signal). It is
better to listening corectly than to speak loudly ;-)

Each project is different, you can't have one only antenna modelisation for everybody.

Test and test again, play with all kind of possible antennas you have and keep in place the best choice, different for each wireless
area coverage...

Have a good luck and enjoy wireless !
