The following lines were added (+) and removed (-):
The first isolator which looks like a black plastic load separating the bottom 70cm portion from the middle 2m portion can be removed leaving only the bottom 70cm portion allowing the antenna to function as a 70cm UHF only antenna. Doing this shortens the wave ratio to match it up perfectly with GMRS frequencies.
