GPS/GNSS Anti-Jam Antenna
8230 AJ
-
The 8230AJ anti-jam antenna is a high gain (40 dB) GNSS outdoor antenna with a unique conical antenna pattern that rejects interference from the horizon. The antenna rejects signals at lower elevation angles – where most of the interference comes from – and only receives signals from higher elevation angles where the true satellites are. This way, you get all the performance and timing accuracy you would with a standard antenna plus 20 dB or more of interference rejection.It uses a three-stage low noise amplifier, a mid- section SAW, and a tight pre-filter to protect against saturation by high level sub-harmonics and L-band signals. The antenna covers GPS L1, GLONASS L1, BeiDou B1, Galileo E1, and QZSS L1.

GPS/GNSS Antenna Signal Splitter 2-Way, TNC Female, IP67 Weatherproof, 1-2 GHz
GPS221
-
INSTOCK Wireless Components, Inc
GPS221 is a two way, passive, GPS signal splitter ideal for splitting a GPS antenna signal between two receivers while providing a DC current path to power a remotely located active GPS antenna from one receiver while blocking the DC path from the other. Furnished with TNC female connectors all ports. A special feature of this unit is the 200 ohm internal load which provides a current drain for the GPS receiver not powering the active antenna. Some GPS receivers incorrectly sense an antenna fault when there is no current draw. The 200 ohm internal load provides a simulated antenna current drain which prevents receiver faulting. Max voltage rating at the DC blocked port is 15 VDC; maximum current rating is 75 mA. Max voltage rating at the DC pass port is 50 VDC; max current rating is 2000 mA.

Omnidirectional Antennas
-
In radio communication, an omnidirectional antenna is a class of antenna which radiates equal radio power in all directions perpendicular to an axis (azimuthal directions), with power varying with angle to the axis (elevation angle), declining to zero on the axis.[1][2] When graphed in three dimensions (see graph) this radiation pattern is often described as doughnut-shaped. Note that this is different from an isotropic antenna, which radiates equal power in all directions, having a spherical radiation pattern. Omnidirectional antennas oriented vertically are widely used for nondirectional antennas on the surface of the Earth because they radiate equally in all horizontal directions, while the power radiated drops off with elevation angle so little radio energy is aimed into the sky or down toward the earth and wasted. Omnidirectional antennas are widely used for radio broadcasting antennas, and in mobile devices that use radio such as cell phones, FM radios, walkie-talkies, wireless computer networks, cordless phones, GPS, as well as for base stations that communicate with mobile radios, such as police and taxi dispatchers and aircraft communications.

Lens corrected antennas are offered with either a circular or rectangular waveguide interface. While lens corrected antennas with a rectangular waveguide interface can only support linear polarization, models with a circular waveguide interface can support various polarization types including horizontal, vertical, left-handed circular, and right-handed circular polarization for broader applications. These antennas are designed and constructed to offer high efficiency, low side lobes and a rugged mechanical configuration. In general, lens corrected antennas are ideal for achieving gain levels of up to 30 dB with moderate side lobe rejections.
