I have a AM HIRK 433MHz receiver and when I'm transmitting signals to it the range is only about 2m compared with 80m as stated in the datasheet.
I have been using a 1/4 wavelength antenna, and have changed to a 1/2 wavelength antenna. This is slightly better but only about 7m. Has anyone got any ideas as to why this is so?
