Delta Meccanica 1356-02-SMA

Product Overview

The Delta Meccanica 1356-02-SMA – 7/16″ DIN Directional Coupler is a precision RF component for sampling forward and reflected power in high-power FM and VHF transmission systems. Its rugged 7/16″ DIN mainline interface and SMA probe ports make the Delta Meccanica 1356-02-SMA ideal for connecting RF power meters, monitoring receivers and protection circuits without disturbing the main feed.

At a Glance

• 7/16″ DIN high-power RF directional coupler with SMA probe ports for measurement and monitoring.
• Designed for broadcast and telecom RF lines where low VSWR and stable coupling are essential.
• Compact, mechanically robust construction for rack, shelter and transmitter room installations.
• Suitable for RF power measurements, return-loss checks and on-air signal sampling.

System Details

Built for demanding RF environments, the Delta Meccanica 1356-02-SMA directional coupler uses a 7/16″ DIN mainline to handle high RF power levels with low insertion loss and excellent matching. The SMA probes provide a convenient low-power sample of the main RF signal that can feed spectrum analysers, power meters or telemetry equipment, helping engineers verify carrier power, modulation and system performance without interrupting service.

Use Cases

Typical applications include permanent installation in FM transmitter output lines, RF distribution systems or test benches where repeatable coupling and robust mechanical reliability are required. The Delta Meccanica 1356-02-SMA is well suited to broadcasters who need a stable reference point for routine measurements and remote monitoring of RF performance across their transmission networks.

Frequently Asked Questions

Can this coupler be left permanently in line?
Yes, the 7/16″ DIN construction and low-loss design make it suitable as a permanent part of the RF chain, providing a continuous sample via the SMA ports for monitoring instruments.

What kind of equipment can be connected to the SMA probes?
You can connect RF power meters, spectrum analysers, modulation monitors, SiteStreamers or telemetry units, provided their input power and impedance ratings match the sampled signal.
