My new home made APT Antenna


This is my new home made APT antenna, which is a cross dipole circular polarization antenna with reflectors. Works for receiving NOAA APT transmissions at 136 MHz




3 days to build and actually the most difficult thing was to gather all the components for the antenna. From the aluminium rods to aluminium boom, the plastic waterproof boxes etc!
