I am looking for an epmp compatible sector antenna (5.4 ghz) with a large (at least 20°) vertical beamwith. Many of our customers live in villages located near but directly below the tower (the antenna vertical tilt is high) and with epmp standard antennas (the max vertical beamwidth is 12°) the ground coverage is very small. Anyone knows antennas that are right for me?
If your horizontal apperture is not very wide (30º or less), you could try a low gain dish.
Or panels, like these:
http://www.streakwave.com/itemdesc.asp?ic=PAT50019&eq=&Tp=&o1=0 [this one is 20ºH and 20ºV], 19dbi
http://www.streakwave.com/itemdesc.asp?ic=MRA50016eDual&eq=&Tp=&o1=0 [this is 38H 30V], 16dbi
http://www.streakwave.com/itemdesc.asp?ic=PAT50014&eq=&Tp=&o1=0 [this is 38H 38V], 14dbi
for every halving of the beamwidth, you get about 3db more gain (considering you keep the same efficiency at the antenna)
the integrated SM has a 30H/20V beamwidth, and should give you a slightly worse performance that the third panel (14dbi one) mostly due to the F/B ratio that is >=20db for the Epmp integrated, and >35db for the itelite 14dbi panel.
IF you can trust the datasheets, that is.
I would hook up an integrated unit as an AP and survey your clients to see what kind of signals they are getting.
Thanks. But in my situation (the costumers are near to ap) it not so importat the antenna gain. The better would be something like canopy fsk integrated antenna (60° x 60°). The 38H 38V it's too tight. Any suggestion?
Good! I will try the last one.
