For those of us using this antenna from Diamond, cutting (trimming) this antenna can be a bit tricky. Fortunately Diamond has a cutting procedure which is explained in the set-up instruction.
I have made a computer program to come to the aid of trimming this antenna. Here are two sample screenshots to explain how it's done (click on an image to view it):
If you are interested in using this nifty program, please contact me for a download link (it's free!).
