Above images show a prototype collinear dipole built for 1090 MHz using this antenna calculator. Note a coax balan is recommended, this is needed to keep current from the antenna off the feed line and back to the TX unit. For receive only, no balan or current choke is needed.
This ground-plane collinear design is superior to the quarter-wave. Besides better reception (gain) it uses a bit more space than the 1/4 wave and is ideal for mast mounting.
