    Hi

    I'm having an serialgateway, and thinking about adding a 433 mhz reciever for implementing my old alarmsystem.

    Is it possible to have two different recivers sharing one antenna?

      @bloody2k - if both recievers are 433mhz - I dont know.
      If you have one 2.4ghz reciever (like nr24l01+ or ESP) then no, its not the same wavelength and requiers different length on the antenna to perform.
