Description

All the filters are VHF band tunable and natural convection cooled. Hundreds of stations use either Electrolink notch filters or Electrolink band pass filters. The fully adjustable input and output coupling provides superior tuning and performance all over the entire VHF band. The notch filters use an all-copper construction providing very low loss with very high notch depth. The bandpass filters use an aluminium construction with copper resonator for stable high power performance. The input power goes up to 10kW (BI) and 20kW (BIII).
