Practical answer: Above 50 MHz, poor connector assembly, excess adapters, moisture, and weak weather seals can add measurable loss and unstable mismatch.
What changes on the air
A connector may pass DC continuity and still be a poor RF transition. Water intrusion and corrosion can create intermittent loss long before the outside looks damaged.
Plan the installation
- Use connectors made for the exact cable.
- Support cable weight and preserve bend radius.
- Seal clean, dry outdoor junctions in serviceable layers.
- Inspect after weather and unexplained changes.
Common mistakes
- Using ordinary tape as the only seal.
- Sealing existing moisture.
- Treating a loose barrel adapter as harmless.
