Linksys ea6900 missing antennas and psu

[moosefist]

I need exactly what the title says. I ordered a used ea6900 and it didn't come with antennas or the proper power brick.

I do not want to spend a ton of money on actual Linksys antennas. Could someone recommend 3 antennas on eBay, Amazon, or newegg that are fairly cheap? I also need a power brick... Hoping to spend less than$25-30 total if possible.

Anyone able to help or at least point me to something for guidance?

Is it this? If so then it appears to use antennas with standard RP-SMA connectors. And the PSU is 12 VDC @ 3.5 A with a barrel connector with positive centre.
