Clarification on DW1810 WLAN Card Main/Aux Antenna Ports (Solid vs. Hollow Triangle)
Hello Dell Support Community,
I am looking for the official hardware specification regarding the antenna port mapping on the Dell DW1810 wireless card (Qualcomm QCA9377).
I have attached a photo of the actual card for your reference. As shown in the image, the card has two antenna connectors on the left side, marked with the following symbols:
-
Top connector: Solid triangle (▲)
-
Bottom connector: Hollow/outline triangle (△)
Could you please clarify the following based on official Dell documentation:
-
Which specific triangle symbol corresponds to the Main port?
-
Which specific triangle symbol corresponds to the Auxiliary (Aux) port?
-
If I only want to connect a single antenna to ensure Bluetooth functionality (since Wi-Fi and Bluetooth share the main RF path on this chip), which port (the one with ▲ or the one with △) should I connect the antenna to?
Additionally, could you please provide the official Dell Service Manual reference or a screenshot that confirms this standard? I want to make sure I am following the official hardware guidelines for this specific module.
Thank you for your help!

Hi
This is my belief.....
The SOLID triangle typically indicates the Main antenna port,
while the hollow triangle represents the Auxiliary antenna port
on the DW1810 WLAN card.
Connecting the antennas correctly is crucial for optimal performance, as the Main port is generally used for Wi-Fi and Bluetooth,
while the Aux port is dedicated to Wi-Fi connectivity.

@anne_droid Thanks for your response
I looked it up—there is a Dell computer model that supports the DW1810 wireless card, as shown in the following link:
https://www.dell.com/support/manuals/zh-hk/vostro-15-3510-laptop/vostro-15-3510-setup-specs/wireless-module?guid=guid-7d8e570c-346e-4bfd-9f0f-7d61b399a716&lang=en-usBased on this model, I found the wireless card installation instructions in the service manual on the official website, as shown in the screenshot.
Does this mean the hollow/outline triangle (△) is for the main antenna and Solid triangle (▲) is for the auxiliary antenna?

The perception when someone looking at an image can see different things. The triangles on Dell wireless card represent:
- white triangle, for connecting to white antenna cable, also known as Main
- black triangle, for connecting to black antenna cable, also known as Aux
