I created a page on the wiki with some learning resources for getting up to speed on the work we're starting to do on antenna design and impedance matching networks:

Since we'll need a VNA for this work I included a comparison of different affordable VNAs.

Tomorrow evening we'll probably spend some time building a simple test setup with two computers displaying the RSSI from the RFM95 modules.
