Multiple WiFI Extenders

[Wichitan]

I need to extend my wifi to 2 outbuildings.  Can I use just 1 Powerline Adapter with 2 Extenders or are these available only as a matched set?  If I can, is there a part number for just the Extender?  Running on Win10.  All buildings connected to same electrical panel.

Not sure how far apart the buildings are from the main and each other. You might be able to make it work with powerline. But powerline is sensitive to interference. 

You can't currently by single devices or a 3 pack that I know of from netgear. But you can mix/match different manufacturer's of powerline devices so long as they follow the same powerline standard.
