Description

Vectronics LP-30 1500-watt HF low pass filter for TV Interference

  It is used and in excellent condition.

The Vectronics LP-30 is a 1500-watt HF low pass filter designed to suppress transmitter harmonics that cause TV interference (TVI). It installs inline between your transceiver (or amplifier) and antenna/tuner. It is a classic USA-made accessory popular in ham radio for clean operation on 160–10 meters.Key Specifications
  • Power Handling: 1500 watts key-down (continuous)
  • Passband: 0–30 MHz
  • Cutoff: ~30–35 MHz
  • Design: 9-pole inverse Chebyshev
  • Insertion Loss: 0.25 dB maximum at 30 MHz (very low)
  • VSWR: < 1.3:1 in the passband
  • Attenuation: Excellent harmonic suppression — typically 60–70 dB at TV band frequencies (e.g., -70 dB at 42–55 MHz video IF and Channel 2)
  • Impedance: 52 ohms
  • Connectors: SO-239 (UHF female) on both input and output
  • Dimensions: Approximately 8.75" × 3" × 2.75"
  • Usage: Place after the transmitter/amplifier and before the antenna or tuner for best TVI reduction. Low loss ensures minimal impact on your transmitted signal.
It works great with modern or vintage HF rigs and legal-limit amplifiers.
