If you intend to stack wheels, they must be special ordered for stacking. Quads, stack 2 duals and feed from splitter with equal lengths of coax.
Wheels are also available for frequencies from 144 MHz to 5 gHz.
Wheels give horizontally polarized omni directional radiation on the horizon with a wide vertical beam width of +/- 35 degrees and cross polarized above and below. Single 50 Ohm type N jack feed point, except on 2.4 gHz which has a SMA. Easily mounted on the top of a mast with a hose clamp around the mating coax plug as shown. Great for hanging down below a balloon and making a reflector behind another one on the ground for receiving rocket or balloon ATV directly below.
