The inputs of the GA3005 are triple-protected against static charge. For coarse protection a fast 60V Gas
Arrestor (max. 1kA 8/20µs) is used, followed by an 8KV ESD protector according to IEC 61000-4 -2 Level 2
/ max. 30ns and another 4KV fine protection.

The integrated over-voltage protection circuit will not protect your equipment from a lightning strike in the event
of a direct hit to the house or the local vicinity. Irrespective of the radiation element lengths, high voltages can
permanently damage the antenna electronics and/or connected devices. For this reason, liability for these
devices is excluded. Other types of damage caused by overloads or by direct HF-exposure (transmitting
antennas) are also excluded from the warranty. In case of absence from home, the potential danger and
subsequent damage of transmitting (ham radio stations), and thunderstorms etc., can be avoided by disconnecting
the antenna cable.

In very rare cases, in the immediate vicinity (distance of a few hundred meters) to very strong transmitters,
overload effects can occur, which can overload the antenna electronics and / or the connected receiver in terms
of level. This is possible with an output level of somewhat more than -20dBm. Weak useful signals can then be
suppressed or phantom signals can be generated. Since the GA3005 receives up to max. 3000MHz, signals
outside the shortwave range can also lead to such negative effects.

Do you have a question about the NTI GigActiv GA3005 and is the answer not in the manual?

Overview

The GigActiv 3005 is an extremely wideband active antenna designed for receiving electromagnetic fields, specifically the E-field component. It boasts a maximum upper cut-off frequency of 3000 MHz, making it suitable for a wide range of applications.

Function Description:

The GigActiv 3005 functions as an active antenna that captures electromagnetic fields. Its design emphasizes a uniform wideband frequency response and vertically polarized omnidirectional reception characteristics. This combination makes it particularly appealing for users of wideband receivers and Software Defined Radios (SDRs) who require broad frequency coverage and consistent performance across the spectrum. The active nature of the antenna means it incorporates internal amplification to boost weak signals, improving overall reception quality.

Important Technical Specifications:

  • Antenna Type: Extremely wideband active antenna.
  • Frequency Range: Responds to the electrical component (E-field) of electromagnetic fields.
  • Upper Cut-off Frequency: Max. 3000 MHz.
  • Reception Characteristics: Uniform wideband frequency response, vertically polarized, omnidirectional.
  • Power Supply:
    • Voltage: 5.5 - 12V DC (max. 120mA) via remote power supply.
    • USB Supply: 5V with possibly slightly reduced IP values.
    • Power Inserter (CPI3000UNI):
      • Input voltage: max. 40VDC, max. 400mA current-limited and protected against polarity reversal.
      • Connectors: 2.1mm DC-power socket (positive inner).
      • Alternatively via optional USB to DC power plug (Part No. 00163-1).
      • HF: BNC.
      • Size/Weight: 86 x 70 x 29 mm / 0.09 kg.
  • Antenna Connector: BNC, 50 ohms.
  • Radiator Connector: M6 screws (stainless steel).
  • Frequency Range (Radiator): 3MHz - 3000MHz (+/-3dB).
    • IP3: >100dBm (@7.00 & 7.20MHz) also in the range 200-3000MHz.
    • IP2: >100dBm (@7.00 & 7.20MHz).
  • Antenna Size/Weight: 68 x 90 x 38mm / 0.12kg.
  • Scope of Delivery: GigActiv GA3005, Power Inserter CPI3000UNI (optional CPI3000DP), 100mm Radiator M6 (black).

Usage Features:

  • Installation:
    • Outdoor Installation: For optimal performance, the antenna should ideally be installed outdoors, away from domestic electromagnetic noise. A typical distance of 5 to 10 meters from any building is recommended.
    • Mounting Height: Contrary to common belief, the highest possible installation location is not always the best. It is often better to mount the antenna near the ground, specifically on a mast that is 2 meters high. This approach reduces exposure to lightning risk and avoids cable resonance effects.
    • Coaxial Cable: Use coaxial cables with the highest possible attenuation, such as Hyperflex 5 (Messi&Paoloni) or H155 (Belden).
    • Grounding: If a metallic antenna mast is used, the coaxial shielding should be grounded near the antenna.
    • Inconspicuous Installation: The design allows for inconspicuous installation for vertically polarized omnidirectional reception.
  • Power Supply Options:
    • The antenna can be powered via a mains adapter or a USB connection (e.g., from a USB power bank). The USB power supply might have slightly restricted IP values, but it makes the antenna suitable for portable use.
    • Power is supplied to the antenna electronics via the connected coaxial cable through the power inserter (CPI3000UNI).
    • The power inserter can be fed by an external power supply. Whenever possible, a transformer-based power supply is preferred over a switch-mode power supply.
    • An optional USB to DC power plug (part no: 00163-1) allows for USB power supply.
    • A self-resetting fuse in the power inserter limits the input current to 400mA in case of a short circuit.
  • Power Inserter Indicators:
    • Green (PWR) LED: Indicates operating voltage.
    • Red (!) LED: Indicates a short-circuit or overload condition.

Maintenance Features:

  • Troubleshooting (Red LED): If the red (!) LED on the power inserter illuminates, it signals a short circuit or overload. In such a case, immediately disconnect the antenna and power cables from the power inserter and investigate the cause of the short circuit or overload before reconnecting.
  • Lightning Protection: While mounting the antenna near the ground (2m mast height) helps reduce lightning risk, proper grounding of the coaxial shielding (if using a metallic mast) is crucial for protection.
  • Environmental Considerations: The antenna is designed for outdoor use, implying a degree of weather resistance. However, specific IP ratings for the antenna itself are not explicitly detailed, though the USB power supply might have slightly restricted IP values. Users should ensure the installation environment is suitable for the device.
  • Fuse Protection: The self-resetting fuse in the power inserter provides automatic protection against overcurrents, reducing the need for manual fuse replacement in case of minor faults.
