Adjustable telescoping dipole antenna

Featured Product from A.H. Systems Inc.

Frequency Wavelength Calculator
This frequency wavelength calculator is useful for calculating the requred antenna element length of a dipole or rod antenna for the frequency of interest.

Product Datasheet

The A.H. Systems' TV-1 adjustable telescoping dipole antenna provides an accurate standard for precise EMI and site attenuation measurements (per OET-55 and ANSI C63.5). This half wave dipole is an ideal solution for Radio/Television broadcast and land mobile radio engineers. The TV-1 is manufactured per the FCC balun design and individually calibrated.

Included parts:
  • TV-1 Antenna Balun
  • 2 adjustible telescoping element
  • 2 extension elements
  • Tape measurer, Inch/Metric
  • ABC-TD, Balun Clamp with 1/4-20 thread
  • Antenna Calibration Manual


Dipole Antennas 25 MHz - 3 GHz
These half wavelength resonant dipole antennas are the foundation of every compliance testing lab. Initial designed by Willmar K. Roberts, these precision made half wavelength dipole antennas are the ideal solution for site attenuation measurements. Each antenna is manufactured with a balun loss of less than 0.5 dB and a VSWR of less than 1.5:1 The half wavelength resonant dipole antenna is the simplest antenna from a theoretical point of view, and are commonly used as a gain reference.
