What Is the Biggest Effect of a Line Isolator?

Function

• Compact high power Common-Mode Choke type 1/1 UNUN.

Mechanical Characteristics

• Professional 50 Ohms N-connector or SO239 connector. (IP66 after sealing with self- vulcanizing tape or equivalent).

Deployable frequency range: 1.5 to 50 MHz

• Low HF variant: optimized for 1,5 – 15 MHz > 30dB Rejection
• Mid HF variant: optimized for 3 – 30 MHz > 30dB Rejection
• High HF variant: optimized for 15 – 50 MHz > 30dB Rejection

Optional Grounding terminal, allowing for connection of one side of the isolator to a clean RF ground, thus forming an “L” configuration filter for sheath currents, and providing additional (secondary) lightning protection. This configuration results in higher TX common-mode current rejection ratios and higher RX noise rejection characteristics.

Maximum power: 6000 W PeP (ICAS) / 3000 W PeP (CCS) / 1500 W DIGITAL (FT8/FT4) (@ antenna VSWR of < 2/1). More info

The common mode rejection performance was measured using two Tekbox current clamps in a differential setup. A wideband noise source was injected, and the resulting signal was analyzed with a spectrum analyzer. The test setup confirmed a wideband common mode rejection of more than +30 dB across the specific band in the HF spectrum.
