Review on Diamond (Original) SRH77CA Dual-Band High Gain Handheld Antenna: Enhanced Reception from 120~900 MHz, 440 MHz Gain, 10W Power, 15" Length by Isaac Simpson

The Diamond SRH77CA is a fairly heavy 15" SMA antenna that offers improvements over standard antennas on some bands. It can be used and works as a dual band antenna for 2m and 70cm transmissions. works well on these bands and is an improvement over the standard docking station. The antenna also works well as a receiving antenna on scanners. It works very well on VHF-Air, VHF-Hi and UHF. It doesn't work very well on the 800MHz band. and higher. It works at 800MHz but isn't even as good as a standard duck antenna. So depending on your usage, this antenna may or may not be an upgrade over the standard duck antenna. Edit: One more note. If you buy this antenna, buy it from a reputable dealer. If you see that it is being sold much cheaper than usual, it is most likely a fake.
