Calibrated for Accuracy
COM-TECH directional couplers are engineered to deliver high directivity, ensuring that your forward power readings are not corrupted by reflected power, and vice versa.
- High Directivity: Essential for accurate VSWR measurements.
- Minimal Insertion Loss: The probe design ensures negligible impact on the main transmission line.
- Adjustable Coupling: Many models feature adjustable loops to fine-tune the coupling factor to your specific metering requirements.
Product Features
1. Rigid Line Integration
These couplers are designed to be installed directly into standard EIA rigid coaxial lines. They are often used as the primary interface for local monitoring units or remote telemetry systems.
- Line Sizes: Compatible with standard rigid line sections (7/8", 1-5/8", 3-1/8", 4-1/2", 6-1/8").
- Broadband Operation: Suitable for FM, VHF, and UHF frequencies without complex recalibration.
2. Dual Directional Options
For complete system visibility, dual directional couplers allow you to monitor both Forward (incident) and Reflected (reverse) power simultaneously from a single section of line.
3. Safety & Protection
These couplers are the first line of defense in transmitter protection circuits, providing the feedback signal needed to trip the transmitter if VSWR spikes due to antenna icing or line damage.
