Hi Jean-Claude,
Yes for 5GHz only you need only the 5GHz antennas. Depending on your environment needs you can choice for omni-directional or sector/patch antennas with different antenna gains.
It's strongly recommended to use support antennas only. When your not familar with external antennas my advise is to contact your local Aruba Partner for the best solution.
When you look for omni-directional antennas Aruba provide two different models for 5GHz, one with 5dBi and one with 10dBi. How higher the attena gain (more dBi) how flatter your "balloon" gets. Remember that a higher antenna gain is most often not always better and depends on your needs.
JW026A ANT-2x2-5005 Pair 5GHz 5dBi Omni N-type Direct Mount Outdoor Antennas
JW027A ANT-2x2-5010 Pair 5GHz 10dBi Omni N-Type Direct Mount Outdoor Antennas
Because your AP is 4x4 you need for example 2x JW026A.
Please don't send PM but just replay in this topic for sharing knownledge ;).

Hi Jean-Claude,
The AP-374 require external antenna's with N-Type connectors that are covered under the aesthetic cover. The AP-375 has internal omni-directional antenna's.
- See the AP-370 datasheet here, link.
- See the AP-370 installation guide here, link.
There are a width range of available antenna options depend on your need. Be sure to use supported antennas only.

Hello Mkk,
Thanks for the reply. I have turned on the Radios but not the external Antennas? I did not know they work hand in hand? I have the option to turn on radios as well as external antennas. Do I set both? I have a 374 but I did not buy extra antennas? Where did you find the configuration because I have looked everywhere for the correct setup?
Thanks again!
- Jean-Claude

Did you set the required gain (dBi) for the external antennas?

How are you powering the 370?
Sounds like the AP is coming up but the radios aren't. Keep in mind the 370s require 802.3at (30W) PoE and that the radios will not work if using 802.3af .

Hello Airheads.
I am having a problem with my 370 Series Outdoor Access Point. The access point did show up in my Aruba vIrtual Controller Interface and I had it attached to my cluster but I could not get any wi-fi signal from it? I then turned on the Ethernet Bridge and all things are lost now. Would any of you know what I could not get wi-fi going even though I saw it in my virtual controller software along with 16 other Access Points? I know it sounds simple but I was trying to do anything I could through the controller software.
Thoughts?
