  Antenna with Integrated Lightning Protection
  The GPSL1GL-TMG-40N timing reference antennas are specifically designed for long-lasting, trouble-free deployments in congested cell-site applications. The low noise, high gain amplifier is well suited to address attenuation issues associated with applications requiring longer cable runs.
  The proprietary quadrifiliar helix design, coupled with multistage filtering provides superior out-of-band rejection and lower elevation pattern performance than traditional patch antennas.
  Their unique radome shape sheds water and ice, while eliminating problems associated with bird perching. The antenna may be purchased by itself or with pipe mounting hardware. Custom models or site kits options are also available.
  This antenna is made of materials that fully comply with provisions stipulated by EU directives RoHS 2002/95/EC.
  The antenna provides integrated lightning protection capability.
  The antenna also features ESD, reverse polarity protection and transit
  voltage suppression.
