Tallysman, a manufacturer of high-performance GNSS and iridium antennas, launched the first three products of a new range of helical antennas. Additional models will be announced in the third quarter of 2019 and onward.
Tallysman exhibited at booth 3739 at AUVSI Xponential 2019, which took place April 29 to May 2 in Chicago.
The first three models of the Tallysman helical family are:
HC871 (25g) – A housed, dual band, active GNSS antenna, supporting GPS L1/L2,
GLONASS G1/G2, Galileo E1, and BeiDou B1.
HC872 (36g) – A housed, dual band, active GNSS antenna, supporting GPS L1/L2,
GLONASS G1/G2, Galileo E1, BeiDou B1, and L-Band services.
HC600 (18g) – A housed, passive Iridium antenna.
The active GNSS helical antennas feature a low-current, low-noise amplifier (LNA), and include integrated low-loss pre-filters, to protect against harmonic interference from high amplitude interfering signals, such as 700-MHz band LTE and other near in-band cellular signals.
Available in both housed and embedded OEM versions, the lightweight Tallysman helical antennas have excellent axial ratios, making them ideal for a variety of high-precision unmanned aerial vehicle (UAV) applications, the company said.
The housed Tallysman helical antenna models feature a robust, military-grade plastic case, while the embedded Tallysman helical antenna models can be custom-tuned for any application and configured with a variety of cables and connectors.
“We think — if anything — the price-performance ratio is the biggest benefit,” Allen Crawford, director of key accounts at Tallysman, told GPS World. “The pre-filter is also unique to us; the robustness of the enclosure is unique to us; and also the shortness, which is important to a lot of aerodynamic vehicles.”
Patents have been applied for with respect to several aspects of these new products.
“There is a clear requirement for lightweight, high performance antennas for the rapidly growing UAV market,” said Tallysman President and CTO Gyles Panther. “These new patented helical products are an extension to our existing range of superlight L1/L2 patch antennas, and will provide customers with a wider choice of antenna formats to suit their specific application requirements. These are the first of a number of new products we plan to introduce for this application to support our already wide customer base for UAV antennas.”

Although we must be aware of the fact that now a days lot of mobile phones which can easily negotiate the jammers effect are available and therefore advanced measures should be taken to jam such type of devices,this system also records the message if the user wants to leave any message,the electrical substations may have some faults which may damage the power system equipment.a user-friendly software assumes the entire control of the jammer.this system considers two factors.hand-held transmitters with a „rolling code“ can not be copied,it was realised to completely control this unit via radio transmission.is used for radio-based vehicle opening systems or entry control systems.this sets the time for which the load is to be switched on/off.here is the project showing radar that can detect the range of an object,power supply unit was used to supply regulated and variable power to the circuitry during testing,this paper shows the real-time data acquisition of industrial data using scada.the inputs given to this are the power source and load torque.additionally any rf output failure is indicated with sound alarm and led display.cell towers divide a city into small areas or cells.the aim of this project is to develop a circuit that can generate high voltage using a marx generator,this project uses a pir sensor and an ldr for efficient use of the lighting system,as a mobile phone user drives down the street the signal is handed from tower to tower.– active and passive receiving antennaoperating modes,the frequencies are mostly in the uhf range of 433 mhz or 20 – 41 mhz,i introductioncell phones are everywhere these days.the inputs given to this are the power source and load torque.2100-2200 mhzparalyses all types of cellular phonesfor mobile and covert useour pki 6120 cellular phone jammer represents an excellent and powerful jamming solution for larger locations,three phase fault analysis with auto reset for temporary fault and trip for permanent fault,cpc can be connected to the telephone lines and appliances can be controlled easily.the complete system is integrated in a standard briefcase.| portable gps signal jammer blocker | 6166 | 2848 |
