Hi!
This is stretching the topic, I'm sorry:
Are there any antennas inside 3-5 y.o. iMacs besides Bluetooth and Wi-Fi?
I think the newest ones have a 2nd Wi-Fi booster to compensate for being in an aluminum housing. This unit pre-dates that.
I looked at various diagrams etc. and I don't see anything else. I'd like to be sure.
Thanks as always!
iMac, OS X Mavericks (10.9)
No, there are no additional antennae. The new Macs have an additional antenna for the 5 MHz Wi-Fi band.
This is very helpful. I'm not certain when the third antenna was added but it seems to be associated with the models with an aluminum back instead of plastic.
Thanks for sharing.
Well, that's a nice assumption but incorrect. The aluminum shells have been in use since 2007, long before Apple had 5 GHz Airport devices. In fact that was before 5 GHz wireless. So I don't think the extra antenna has anything to do with the case being made from aluminum.
Thanks for the correction and answer.
If anyone knows, I'm wondering if the dangling wires that connected to a now-absent WF antenna can pick up a meaningful transmission--or broadcast one. Assume a very powerful local source, and note that the WF board has been removed too.
I fed the wires out the RAM hatch and am wondering how best to secure them.
Please don't underestimate the power of the malicious attacks.
Thanks!
