The turnstile antenna. Good for long distance but not high altitude. The best way to mount this antenna is probably not the way you think. Mounted properly this antenna will give good reception to the front rear and sides. Best used on the aircraft with the moxon on the ground. Although you may find that the vee antenna is a better antenna for in the air.
