Authentic Genuine Nagoya UT-72 Super Loading Coil 19-Inch Magnetic Mount VHF/UHF (144/430Mhz) Antenna PL-259 from amazon is what I use on top of my Suburban. Nice Increase in performance compared to the factory setup. At home I use Dual Band Portable roll up VHF UHF Antenna (MURS, HAM, GMRS, commercial) DBJ-2 from ED Fong off eBay, its not fancy but no complaints from me. Still testing to see if i get better range with it then the Nagoya. Semper Fi and Happy birthday.
