1090MHz 2.2dBi Sleeve Dipole Antenna This 1090MHz sleeve dipole antenna is custom made for Pants for Birds, and is suitable for outdoor installation. 1090MHz antennas connect to the 1090 port on an ADSBee 1090U, and are used to receive Mode S / ADS-B data.

1090MHz PCB Antenna 1090MHz PCB antenna with a foam adhesive backing, suitable for attachment to foam or thin plastic. Antenna is vertically polarized, and should be oriented up-and-down (like a tree) relative to the horizon.

978MHz Sleeve Dipole Antenna This portable antenna can be used for receiving UAT transmissions on 978MHz. It has an SMA male plug and can be mated with an SMA female jack. The elbow allows the antenna to be poised at a variety of angles; UAT transponders use vertically polarized antennas, so you’ll want this antenna to be aligned vertical to the ground for best reception. The coaxial sleeve dipole internal structure of this antenna creates a relatively omnidirectional gain pattern with a peak gain of 2.1dBi around the horizon, which is useful for receiving aircraft at a wide range of azimuths and elevations. This is a high quality antenna that has been custom designed and manufactured for Pants for Birds by a major US-owned antenna manufacturer that also manufactures millions of antennas for Apple and Google (among others). Representative test data for this sleeve dipole antenna is included in the image gallery.
