GPS/AVIATION SPECIAL PURPOSE ANTENNAS
GPS Timing Reference Antennas
40 dB GPS L1/GLONASSL1/GALILEO E1 Timing
Antenna with Integrated Lightning Protection
The GPSL1GL-TMG-40N timing reference antennas are specifi cally designed
for long-lasting, trouble-free deployments in congested cell-site applications.
The low noise, high gain amplifi er is well suited to address attenuation issues
associated with applications requiring longer cable runs.
The proprietary quadrifi liar helix design, coupled with multistage fi ltering
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.
