Models

• 3144 Log-Periodic Dipole Array — The Model 3144 Log-Periodic Dipole Array (LPDA) Antenna is a standard medium gain log-periodic dipole array. Frequency range: 80 MHz to 2 GHz.
• 3145 BDP Dual-Polarized Log-Periodic Dipole Array — The Model 3145BDP Dual-Polarized Log-Periodic Dipole Array (LPDA) is a dual linearly polarized, broadband log antenna designed to operate over the frequency range of 100 MHz to 1.1 GHz. Frequency range: 100 MHz to 1.1 GHz.
• 3147 Log Periodic Dipole Array Antenna — The Model 3147 Log Periodic Dipole Array Antenna is primarily designed for use with the FCC Part 15 and has excellent VSWR characteristics throughout its entire operating frequency range, as well as relatively constant linear gain. Frequency range: 200 MHz to 5 GHz.
• 3148B Log-Periodic Dipole Array — The Model 3148B Log-Periodic Dipole Array (LPDA) Antenna is specifically designed for making CISPR 16-1 measurements using an engineering and manufacturing process that offsets all its elements in a precision pattern. Frequency range: 200 MHz to 2 GHz.
• 3150B Dual Stacked LPDA Antenna — The Model 3150B Dual Stacked LPDA is a dual stacked log periodic array antenna (LPDA), with each of the two LPDAs being 100 Ω antennas. Frequency range: 80 MHz to 1 GHz.
• 3151 Log-Periodic Dipole Array — The Model 3151 Log-Periodic Dipole Array (LPDA) Antenna has a space saving design using a top hat-loaded, low-frequency elements. Frequency range: 20 MHz to 220 MHz.
• 3186 Dual Stacked LPDA Antenna — Model 3186 is a dual stacked log periodic dipole array antenna (LPDA), where each of the two separate LPDAs comprising the dual array are 100 antennas. Frequency range: 1 GHz to 18 GHz.
• 3170 Intell-I-Tune Log Periodic Antenna — ETS‑Lindgren’s Model 3170 Intell-I-Tune Antenna Solution achieves true resonance across 30–200 MHz, delivering 200 V/m from the fundamental frequency to meet MIL-STD-461G/H RS103, DO-160, and ISO 11452-2 requirements. Its patented auto-tuning system reduces harmonics, lowers amplifier power needs, and enables fully automated operation for greater accuracy, efficiency, and throughput in EMC testing. Frequency range: 30 MHz to 200 MHz.
