Narrative:
Enroute we asked to deviate for weather (WX). We were IMC and deviating; when our radios had a lot of static interference. It became very difficult to understand what center was instructing us to do. At the same time; we got a WX/ant annunciator on our navigation display and our WX radar went blank. We switched to system 2 and after less than a minute; we got the same WX/ant annunciator. I switched between the two systems in order to get some type of radar return. We were unable to get vectors from centers as we were unable to hear them. We encountered moderate turbulence on the heading we were on; so we took a heading which we thought would get us out of the weather we were encountering. We were finally able to reach another [company] aircraft; on frequency; and they were able to relay ATC instructions to us.
