Hansch Tetra Vehicle Antenna

Hansch EDR TETRA vehicle antenna - combined vehicle antennas and antenna whips

The 7610106-H and 7620106-H are roof-mounted TETRA/TETRAPOL antennas with a flexible antenna base and an integrated active GPS unit. The GPS section is an active ceramic patch antenna mounted on a PCB, with RHC right-hand circular polarization. Its frequency is 1575.42 MHz, nominal impedance is 50 ohm, LNA gain is 26 dB, noise figure is 1.8-2.2 dB, supply voltage is 3.0-5.5 V DC and current consumption is 10-30 mA. The polarization of the radio antenna section is vertical.

What frequency ranges do Hansch TETRA antennas cover?

The TETRA section of the 7610106-H covers 380-430 MHz with a 1/4 wave design. TETRA gain is 0 dB or 2.14 dBi, while VSWR is below 2.0. The 7620106-H covers the 380-510 MHz UHF range with a 5/8 wave design, has a nominal impedance of 50 ohm and also has a VSWR below 2.0. The GPS section of both combined antennas operates at 1575.42 MHz.

Hansch 7610106-H and 7620106-H TETRA/GPS antenna mechanical specifications

Both combined antennas measure 95 x 52 mm, with an above-roof height of approximately 44 mm and an installation depth of approximately 15 mm. The required mounting hole diameter is 19 mm, while the antenna whip connection is M5. The materials are ABS, POM, PE and steel, and the antennas are black. The 7610106-H weighs approximately 150 g and its antenna whip is approximately 130 mm long. The 7620106-H weighs approximately 170 g and its whip length is approximately 500 mm depending on frequency.

• GPS frequency: 1575.42 MHz
• GPS LNA gain: 26 dB
• GPS supply voltage: 3.0-5.5 V DC, 10-30 mA
• Impedance: nominally 50 ohm
• Polarization: vertical, RHC for GPS
• VSWR: below 2.0
• Antenna whip connection: M5
• Mounting hole: 19 mm

What is the difference between the two combined TETRA/GPS vehicle antennas?

The main difference is the design of the RF antenna section. The 7610106-H uses a 380-430 MHz, 1/4 wave antenna, while the 7620106-H uses a 380-510 MHz, 5/8 wave whip. The whip of the 7610106-H is approximately 130 mm long, while the whip of the 7620106-H is approximately 500 mm long depending on frequency. The main electrical specifications of the GPS unit, housing dimensions, mounting hole and M5 antenna whip connection are the same for both versions.

Hansch UHF/VHF and TETRA/LTE antenna whips

The 7620 UHF/VHF roof antenna whip operates as a 1/4 wave antenna in the 130-230 MHz VHF range and as a 5/8 wave antenna in the 380-510 MHz UHF range. Its nominal impedance is 50 ohm, polarization is vertical, and gain is 3.15 dBd or 5.15 dBi. Bandwidth is 30 MHz, VSWR at frequency resonance is below 1.5, and maximum power is 50 W. Its length is approximately 570 mm depending on frequency, its weight is approximately 42 g, and it uses an M5 thread. It can be used as a replacement part for the 7620106-H combined antenna.

What role does the Hansch TETRA/LTE antenna whip serve?

The TETRA/LTE antenna whip covers the 380-430 MHz TETRA range as well as the 790-960 MHz and 1710-2700 MHz LTE frequency ranges. It uses a 1/4 wave radiator design and is intended as a concealed antenna solution for combined antennas. Its weight is 0.04 kg and it is listed as a replacement part for the combined TETRA/GPS mobile antenna. The Hansch range therefore includes both complete combined antennas and separate UHF/VHF and TETRA/LTE antenna whips.
