Externally-connected antennas: Which ones are 2.4GHz? Which are 5GHz?

[Ichinisan]

It's never labeled on the antennas nor on the connectors at the adapter. Does each antenna have 2 antenna wires inside?

My mini-ITX board has a Broadcom Bluetooth / 802.11ac module. Does Bluetooth also use the external antenna?

Only one wire, they tend to be combo antenna which means they are compromises. BT probably uses the 2.4ghz antenna.

antennas are supposed to be marked.

No master what External Antenna is always better then Internal.

Antennae propagates Signal the more they are out without obstructions the Better they are.

in Addition Como Antennae are always based on compromises individual Antenna that re tuned to its specific Frequency are always better.

Maybe I should not use the one that came included with my motherboard then. Even if I get an external antenna that says which connector is 2.4GHz and which is 5GHz, it still isn't marked on the motherboard's I/O shield. I may have to look directly at the module and follow circuit traces...

I can't seem to find a 5GHz-specific indoor antenna.

Found this outdoor antenna that seems to be 5GHz-specific:

you probably want indoor 2DBi

and you are right, the 5GHz only antenna seem to have disappeared. Found some.

Mount one of these and rule your block :biggrin:

found one but this is from manufacturer website but there is an order form so.

I guess it wouldn't do any good to have a perfectly tuned 5GHz-only antenna for my desktop computer if I can't identify which of the 2 connectors is 5GHz. It's an ncase M1, so I still haven't bothered to look. I'd have to pull out the 2x120mm radiator to see anything.

easy to check, note signal strength of 2.4, remove antenna, attach 5ghz and see 2.4ghz strength :biggrin:


Preferably from some distance.


why is your desktop on wireless?

It's wired. I was just curious.

For a few days, I was using wireless from a neighbor while I was in the process of moving to a new place.

For desktop I would get an external one with usb extension cable. Easier to put it at an optimal location for reception.

My Asrock mini-ITX motherboard included a module with Bluetooth 4.0 adapter and 802.11ac -- The chipset is either Intel or Broadcom [edit][WiFi is definitely Broadcom][/edit]. 2 antenna connectors from the mPCI-E card lead to the i/o shield. The external antenna has 2 long cords that connect to the i/o shield, so there is flexibility in placement comparable to an external USB stick with an extension cord. I figure mPCI-E can generally use more amps than USB anyway.

Neither the i/o shield nor the cords from the external antenna are marked for 5GHz/2.4GHz.

Not marked in the manual either?
