For portable handheld operations is the Remtronix 700/800/900mhz antenna really the best upgraded antenna? I have a BCD325P2 and it has the standard rubber ducky on it. I have other antennas for when it is home but want to maximize the reception when I am portable. I hear people talk about the Remtronix all the time and just wanted to make sure it is worth it or if there is another one I should be getting. Thanks!
