Signal SD-AN-850 3.5dB Compact Conical External Antenna with Grounding Kit

The Signal SD-AN-850 is a compact, low-profile 3.5dB omnidirectional LTE antenna designed for use with Signal SDS Series 4G/3G modems and wireless devices. Engineered for reliable mobile and fixed data performance, this antenna offers excellent coverage across a wide frequency range of 698–2700 MHz, making it ideal for improving wireless connectivity in remote or enclosed installations.

Housed in a UV-stable black polycarbonate radome, the SD-AN-850 is rated IP65 for weather resistance and is fitted with a 16mm stud mount and integrated O-ring seal for secure, leak-proof outdoor mounting. It includes an RG58 coaxial cable with SMA male connector and is supplied with a grounding kit for complete installation.

Its sleek conical shape allows for minimal overhead clearance—ideal for use in control boxes, field enclosures, or pit lids—while maintaining robust signal performance for Signal SDS controllers using the SD-MD modem or other wireless modules.
