Description


Tekbox TBMA1B Biconical Antenna 30MHz – 3GHz

The TBMA1B is a small, lightweight, wideband biconical measurement antenna. With its moderate price, it is targeting radiated noise EMC pre-compliance testing and generating defined field strengths.

It is characterized from 30 MHz to 3 GHz and has a directional pattern similar to a dipole.

The TBMA1B comes in an aluminum carrying case, together with a “pistol-grip” tripod. A standard ¼” thread makes it easy to connect it to most standard tripods.

The elements are corrosion resistant and constructively locked against rotation. They are fed via a wideband balun with 2 W power handling capability. Furthermore they are protected against build-up of static charge.

Features:

  • Type: Passive Biconical
  • Frequency range: 30 MHz – 3000MHz
  • Isotropic gain at 3m spacing: -38.46 … 1 dBi
  • Antenna factor at 3m spacing: 17.24 … 51.20 dB/m
  • Maximum continuous input RF power: 2W
  • Nominal impedance: 50 Ω
  • RF Connector: N type female
  • Matching: 1:2 transformer + 1:1 balun
  • Tripod Adapter Thread Size: 1/4 “
  • Mechanical Dimensions: L x W x H: 430.73 mm x 163.08 mm x 138.79 mm (16.96” x 6.42” x5.46”)
  • Weight: 0.46 kg (1.01 lbs)
