    Hey Everyone!
    I just used an RF transmitter and Receiver of 315Mhz to send and receive data through PIC18 Controller!
    First I used a monopole straight antenna with it and it was working fine! Then something went wrong! Now the receiver just receives data for once and then doesn't altogether!
    Also, when it was working, it just worked in line of sight scenario!
    Could some one help me with it please and also I would be very thankful if someone could explain to me the specs I require if I need to mount a helical antenna on it rather than a monopole one?
    Or how can I increase it's distance of communication?

    I have attached a picture of transmitter and receiver I am using! I would be very thankful If I could get some pointers on how to solve this issue!

    I did some testing on similar ebay RF modules here;

    You can see the simple wire stick antennas there that I used.

    Do you have a 'scope? What kind of data are you sending?

    Hey THE_RB,Thank you so much for this! This was great help especially because of the widths as they werent same but using another protocol might help me to cope with this issue somewhat better!
    Thanks again! :)
