Antenna Cut Chart
Several antennas can look similar or have had the same name over the years. Please confirm you have the correct antenna by checking the visible description and photos with each antenna.
Antenna length are VERY important to two-way radio range. When we ship you an antenna, it is pre cut to "Mid" or 151.625. If you are using a higher frequency or would like to do some additional tuning, you can reference these cut charts. We will tune your antenna free of charge at a race our at HQ, please feel free to call us or message us with any questions!
