Does anyone here have antenna patterns for RBMetalG-52SHPacn? I need it for Ekahau Site Survey.
How can anyone have it if its not in the Mikrotik Site?
Anyways, its an omni directional antenna, thats why i guess no pattern exists…
RBMetalG-52SHPacn has no built-in antenna, you can attach any kind of antenna to this router.
I mean the antenna pattern of the omni directional antenna included in the packaging of RBMetalG-52SHPacn.
There is the Omni Antenna included with the packaging of RBMetalG-52SHPacn.
Do you have the antenna patterns of that Omni Antenna?
Do you know what an omnidirectional antenna is ? Do a google search…
To (probably unjustly) defend @Jerboy: omnidirectional usually refers to horizontal pattern … while vertically such antennae are not omnidirectional (or else they would actually be called isotropic … and we all know that in reality there’s no such thing as isotropic antenna, right?).
Not with antena gain of 6dBi as in case of referenced device.
Sure @mkx… the elevation of an omnidirectional would be really small.. we mostly care about the azimuth pattern, x axis as you said…
Draw a circle on a piece of paper and you just got a pattern for the omnidirectional antenna.
Not if one wants to cover two floors indoor … even if the floor/ceiling has low RF attenuation (I guess some old-style wooden houses floors might allow slightly better signal penetration through ceilings/floors), space exactly above/below such AP would have worse signal coverage than a few metres away …
But I agree, this is probably not OP’s case … he should use any omnidirectional antenna available within his RF propagation prediction tool of choice, set antenna gain to 6dBi and the results should be as close to reality as possible (read: most of time fiction, with some luck resembling reality).
“omni” = “dipole” … toss that in Google.. basically a sphere with top and bottom chopped off and that energy spread out on the horizontal axis (thus the 2 db gain).
Assuming you want horizontal coverage (single story building for example..), dipoles should be oriented perpendicular to the ground, or parallel to the force of gravity.
FYI - a dipole is roughly “a wire”
