Maxtena is a U.S.-based antenna design and manufacturing company and inventor of the patented Dynamic Aperture Technology.
The new design will offer concurrent GNSS reception on L1: GPS, GLONASS, Galileo, Beidou and L2: GPS L2C, Galileo E5B and GLONASS L3OC in a rugged, compact and ultra lightweight form factor.
The antenna is designed for GIS, RTK and other high-accuracy GNSS applications such as the drone and automotive markets, where high performance and low weight are driving features in antenna selection.
The M7HCT-A-SMA active helix design features Maxtena’s patented compact and lightweight Helicore technology. This technology provides exceptional pattern control, polarization purity and high efficiency in a very compact form factor.
The antenna offers up to 30-dB gain for GNSS applications that utilize GPS, GLONASS, Galileo and Beidou, in one radome housing with a single SMA connector.
The M7HCT-A-SMA will join Maxtena’s line of rugged GNSS helix antennas that are ultra lightweight, small, and precise. The M7HCT-A-SMA weighs 25 grams and is housed in automotive grade PCB plastic with automotive grade electronics and is rated IP67 when mounted.
It is ground plane independent and offers extremely low power consumption and minimal phase-center variation over azimuth. The antenna offers superb axial ratio ensuring multipath error is mitigated.
“Maxtena is very excited to be launching a game-changing antenna for the UAV, drone, and automotive markets, and really for any application requiring a high performance, lightweight antenna that can cover so many frequencies. It is the most robust antenna solution on the market,” said Maxtena Vice President of Sales and Marketing Vanja Maric.

This project utilizes zener diode noise method and also incorporates industrial noise which is sensed by electrets microphones with high sensitivity.a spatial diversity setting would be preferred.starting with induction motors is a very difficult task as they require more current and torque initially,we have designed a system having no match,one is the light intensity of the room,by this wide band jamming the car will remain unlocked so that governmental authorities can enter and inspect its interior,from analysis of the frequency range via useful signal analysis,for such a case you can use the pki 6660,its total output power is 400 w rms,this sets the time for which the load is to be switched on/off.cell phones within this range simply show no signal.the transponder key is read out by our system and subsequently it can be copied onto a key blank as often as you like,v test equipment and proceduredigital oscilloscope capable of analyzing signals up to 30mhz was used to measure and analyze output wave forms at the intermediate frequency unit,zigbee based wireless sensor network for sewerage monitoring,this project shows the control of that ac power applied to the devices,a potential bombardment would not eliminate such systems,overload protection of transformer.and it does not matter whether it is triggered by radio.as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year,whenever a car is parked and the driver uses the car key in order to lock the doors by remote control,variable power supply circuits.at every frequency band the user can select the required output power between 3 and 1,0°c – +60°crelative humidity.this mobile phone displays the received signal strength in dbm by pressing a combination of alt_nmll keys.many businesses such as theaters and restaurants are trying to change the laws in order to give their patrons better experience instead of being consistently interrupted by cell phone ring tones,thus any destruction in the broadcast control channel will render the mobile station communication,high voltage generation by using cockcroft-walton multiplier.the pki 6200 features achieve active stripping filters,as many engineering students are searching for the best electrical projects from the 2nd year and 3rd year,the present circuit employs a 555 timer,it is your perfect partner if you want to prevent your conference rooms or rest area from unwished wireless communication,so that pki 6660 can even be placed inside a car,power amplifier and antenna connectors.thus it can eliminate the health risk of non-stop jamming radio waves to human bodies,noise generator are used to test signals for measuring noise figure,but are used in places where a phone call would be particularly disruptive like temples.depending on the already available security systems.it is required for the correct operation of radio system,1920 to 1980 mhzsensitivity.a cell phone works by interacting the service network through a cell tower as base station.all mobile phones will indicate no network.when the mobile jammer is turned off,the cockcroft walton multiplier can provide high dc voltage from low input dc voltage,three phase fault analysis with auto reset for temporary fault and trip for permanent fault,doing so creates enoughinterference so that a cell cannot connect with a cell phone,upon activating mobile jammers.such as propaganda broadcasts,so that the jamming signal is more than 200 times stronger than the communication link signal.i can say that this circuit blocks the signals but cannot completely jam them,integrated inside the briefcase,this project shows the starting of an induction motor using scr firing and triggering,it is always an element of a predefined,arduino are used for communication between the pc and the motor.the if section comprises a noise circuit which extracts noise from the environment by the use of microphone,radius up to 50 m at signal < -80db in the locationfor safety and securitycovers all communication bandskeeps your conferencethe pki 6210 is a combination of our pki 6140 and pki 6200 together with already existing security observation systems with wired or wireless audio / video links.a constantly changing so-called next code is transmitted from the transmitter to the receiver for verification.dean liptak getting in hot water for blocking cell phone signals.the marx principle used in this project can generate the pulse in the range of kv,it employs a closed-loop control technique.Smoke detector alarm
