Antenna Cutting Chart Page
   
We use a dremel with a cutting disc to cut
all our stainless steel antenna whips. If you don't have a dremel handy, you can
use a triangle or similar file and file a deep notch at the point where you want
to cut the antenna. Snap the antenna at the notch. Then file the antenna
smooth. When cutting any antenna rod, please take care and always wear eye
protection
