I'm looking for a dual band 3x3 MIMO antenna to use with the AP-224 in a VHD environment. I'm looking for options with 30 degress or close to it. Could you please recommend the manufacturer and model for it?
Aruba provides a 60 degree option but I need less degrees.
Aruba doesn't produce a 30deg x 30deg dual band antenna. The closest option is a dual-band 60deg. If you want to share your setup and requirements, I might have more information to offer, just let us know.
What AP model are you planning to use? If the AP-228, then you can use separate 2.4 and 5Ghz antennas since those antenna connectors are not diplexed. However, using your numbers, to generate a cell for an approx 75x50m area at 15m AGL, 30deg would not be enough beamwidth, you would need ~60-90 deg min.
Assume radius of 35m (to cover approx 70x70 for easy math), at 15m height, drawing a right triangle, that angle at the top would be approx 60deg, for a 120deg beamwidth need. Using a 60deg or 90deg antenna would be determined by your spacing/overlap ratio plans. But 30deg seems kind of narrow for such a small cell at such a short height. A 30deg antenna aimed straight down at 15m elevation would give a coverage of 4m radius or 8m diameter. That's too small.
I'm considering this TerraWave antena http://www.terra-wave.com/shop/245-ghz-65-dbi-dual-band-mimo-antenna-with-rpsma-plug-connector-p-3680.html
35 cells in a 50x75m area? Makes more sense...Just note that Aruba doesn't support the use of 3rd party antennas (we can't validate their radio and RF characteristics), so this would be a use at your own risk kind of antenna solution for the 224 and warrants testing. Unfortunately, Aruba as a vendor doesn't make RP-SMA-based 30deg dual band high gain antennas.
I have a similar scenario.
A few 200 person seating sections, sitting 35.5 feet high at the center of the section, angled about 40 degrees. Antenna is 55 feet high, giving a 19.5 height in relation to the seating sections. 30x30 degree antenna would give me about a 39ft fresnel at the seats. The ANT-4x4-5314 would cover me for 5Ghz, but i haven't a solution for the 2.4. A 3x3 version of the ANT-2x2-2314 would be a good fit. But this will only work using an AP-228. Since there is no 30x30 degree RP-SMA antenna it seems I cannot use the AP-224. With a 30x30 degree I was going to use 2 APs per section.
Would need to use the 228 with RP-SMA to N jumpbers, then the 5314 and 2314 antennas mounted separately. There are functional design considerations in making a 30x30deg dual-band antenna (it usually ends up where the 5Ghz is significantly narrower).
The vast majority of clients only support 2x2 capability anyways. Unless you can control the capabilities of all clients to make them 3x3, it might not be a big difference.
