Goodmorning everyone, someone would advise me which of the following two bluetooth antennas is best to use with the wifi / bluetooth (4.0) module BCM94331PCIEBT4CAX for a “MacBook Pro 17 Late 2011”?

  1. K17 056-3518-A
  2. 631-1570-10 I ask which of the two antennas will be able to offer greater coverage and stability of the bluetooth signal. Thanks for the assistance!

This is the correct part Unibody MacBook Pro 17 Airport Antenna (2011) - Apple P/N 631-0890-B. There is no options here.

You’d be better to get a new dual band usb AC wifi/bluetooth 4.0 combo dongle for a little more (prob about 50.00 and this antenna only is 27 and tax plus shipping and also used…..) and you’d have AC wifi and newer Bluetooth, but it is a usb connection instead of internal so unless you REALLY want internal only you’d gain much more with a newer AC wifi/BT 4.0 dongle for a few bucks more.
