Each section is adjustable to tune in the associated band.  Adjustments are made by loosening an Allen screw and moving a section up or down guided by your SWR meter.== SWR Tuning ==== Experimenting ==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.  [[Category:Electronics]][[Category:Radio]][[Category:HAM Radio]][[Category:Tangible Product]]
