The Parsec Rottweiler PRO5R2L2WG15BS is the short-bolt variant of the 5:1 Rottweiler PRO Series antenna. It combines 2x2 MIMO 4G/5G cellular, 2x2 Wi-Fi and GPS in a single omnidirectional housing, and it replaces the standard 1.25 in mounting bolt with a 0.6 in bolt for installations that call for a shorter mounting stud. The electrical design matches the standard PRO5R2L2WG15B. It is aimed at emergency fleets, police cruisers, transportation, remote video monitoring, industrial IoT and fixed wireless access. The cellular elements cover 698-960, 1710-2700, 3400-4000 and 5150-5925 MHz, with published North American bands including B14, B41/n41, B48/n48 and n77. Cellular peak gain reaches 8.5 dBi at 3400-3800 and 5150-5925 MHz, where radiated efficiency peaks at 85 percent. The two Wi-Fi elements cover 2.4 GHz and 5 GHz bands with up to 9 dBi peak gain and are rated Wi-Fi 6 compatible. The GPS element operates at 1575.42 MHz with a 28 dB preamp. The radome stands roughly 1.45 in tall. The housing is IP67 rated and power-wash safe, and it is built for high vibration, debris and inclement weather, with an operating range of -30 °C to 85 °C. It mounts through a single 1 in hole. Five 15 ft cables connect to your equipment: LSR200 with SMA male for cellular, LSR200 with RP-SMA male for Wi-Fi, and LSR100 with SMA male for GPS. Parsec offers a magnetic mount, a mini pole mount bracket, an L bracket, vehicle gaskets for the Dodge Charger and Ford Explorer, and surge arrestors for the Rottweiler family. Parsec also publishes a datasheet and a Rottweiler installation guide for this antenna.
