Array Antennas (2)

Several in-line radiators stacked to squash the pattern toward the horizon.

Two crossed dipoles fed in quadrature for circular or omnidirectional coverage.

The omnidirectional vertical whips that carry voice between controllers and aircraft.

A wide row of antennas past the runway end that defines the approach centerline.

A ground beacon whose circular antenna array lets aircraft read their bearing from the station.

A short, coiled flexible antenna that fits a quarter-wave into a stubby package.

A taller-than-quarter-wave vertical that pushes more energy toward the horizon.

A disc-over-cone vertical with enormous bandwidth and an omnidirectional pattern.

A quarter-wave vertical with radials that form an artificial ground.

🔧 Buildable at home

An end-fed half-wave vertical matched by a quarter-wave parallel stub.

🔧 Buildable at home

A single vertical quarter-wavelength rod that works against a ground plane.

🔧 Buildable at home

A flexible rod monopole used on vehicles and portable radios.

A dipole made from a closed loop of two parallel conductors for higher impedance and bandwidth.
