That&#8217;s why everybody started buying RF amplifiers and sharkfin antennas to hang off their bags.<\/div>\n<div style=\"color: black; font-family: helvetica, arial, sans-serif; font-size: 15px; padding: 0px; margin: 0px;\"><\/div>\n<div style=\"color: black; font-family: helvetica, arial, sans-serif; font-size: 15px; padding: 0px; margin: 0px;\">Now that the SRb&#8217;s are available, those RF amps and Sharkfins will probably overload the front-ends of the SRb&#8217;s.
