The 'Orbitor HD' is the original Heavy Duty spring coiled baseload CB Antenna from Thunderpole. Don't be fooled by cheap imitations! It is ideal for most vehicles as it is pre-tuned and has strengthened connecting parts. It also has a large spring coil that gives it top-end performance and withstands most knocks and bumps, which makes it suitable for more demanding applications, such as off-roading.
