Custom Antenna
Assemblies
Fully integrated antenna systems built to your specifications. We combine reflectors, feeds, waveguide networks, and mounting hardware into turnkey assemblies for satellite, radar, measurement, and communications applications.
Your Requirements. Our Engineering.
Not every antenna application fits a standard product. When your system demands a specific feed configuration, integrated waveguide network, custom mounting geometry, or environmental protection that goes beyond off-the-shelf options, our custom assembly program delivers exactly what you need.
RF Essentials engineers work directly with your team from initial requirements through final acceptance testing. We integrate our full product line of reflectors, horn antennas, waveguide components, and mechanical hardware into complete antenna sub-systems. Every assembly is designed, fabricated, tested, and shipped from our facility in the United States.
Assembly Types & Integration Options
Complete prime focus or Cassegrain antenna systems with integrated feed horns, OMTs, polarizers, and waveguide-to-coax transitions. Includes mounting pedestals, alignment hardware, and optional radome protection. Configured for your frequency band, gain requirements, and installation environment.
Integrated feed assemblies combining horn antennas with waveguide networks, power dividers, couplers, and filtering. Designed for multi-band, dual-polarization, or multi-beam configurations. Used in SATCOM ground terminals, radar systems, and antenna measurement ranges.
Horn antennas with pre-assembled waveguide runs, bends, twists, and transitions. Eliminates field alignment and reduces installation time. Available with standard or custom flange interfaces and mounting brackets for rack or platform integration.
Calibrated antenna assemblies for antenna ranges, EMC testing, and RF characterization. Includes reference horns, calibration data, mounting fixtures, and interconnect hardware. Configured as complete measurement-ready systems with full traceability documentation.
Integration Capabilities
Build assemblies around any RF Essentials antenna: prime focus reflectors, Cassegrain systems, horn lens antennas, conical horns, and standard gain horns. Mix and match for multi-band or multi-function systems.
Custom waveguide runs with precision bends, twists, transitions, and adapters. All joints are aligned and torqued to specification. Pressurization ports available for outdoor and high-altitude installations.
Integrate OMTs, polarizers, couplers, filters, LNA mounts, and HPA interfaces directly into the antenna assembly. Reduces system-level interconnects and simplifies field deployment.
Custom mounting pedestals, elevation-over-azimuth positioners, alignment fixtures, and structural brackets. Designed for your installation constraints including weight limits, wind loading, and vibration requirements.
Radomes, weather seals, corrosion-resistant coatings, and thermal management for outdoor and harsh-environment deployments. Designed for continuous operation in rain, humidity, temperature extremes, and salt fog.
Every assembly undergoes full RF acceptance testing on our calibrated antenna range. Gain, VSWR, radiation patterns, and cross-polarization data included. Extended test reports and compliance documentation available.
From Concept to Delivery
Share your frequency, gain, polarization, mechanical, and environmental requirements. Our engineers evaluate feasibility and recommend the optimal configuration.
Full-wave electromagnetic simulation validates RF performance before fabrication. Mechanical CAD models confirm fit, alignment, and integration with your platform.
Precision CNC machining, assembly, and alignment of all antenna and waveguide components. Quality inspection at every stage ensures dimensional and electrical compliance.
Full RF acceptance testing on our in-house antenna range. Measured data package included with every shipment. Ongoing support for integration and field deployment.
Where Custom Assemblies Deploy

Frequently Asked Questions
A custom antenna assembly is a fully integrated antenna system built to your specific requirements. It combines reflectors, feed horns, waveguide networks, transitions, mounting hardware, and environmental protection into a single turnkey unit. RF Essentials engineers work directly with your team from requirements through final acceptance testing.
We build assemblies around any of our standard antenna types: prime focus reflectors, Cassegrain systems, horn lens antennas, conical horns, and standard gain horns. Assemblies can include integrated feed networks, OMTs, polarizers, waveguide runs, LNA or HPA mounting provisions, radomes, and custom mechanical structures.
Lead times depend on complexity. Simple feed-plus-waveguide assemblies typically ship in 4 to 6 weeks. Full reflector systems with custom feeds, integrated electronics, and environmental protection may require 8 to 16 weeks. Contact our engineering team with your requirements for a project-specific timeline.
Yes. Every custom antenna assembly ships with measured performance data including gain, VSWR, radiation patterns, and polarization characteristics. Testing is performed on our in-house calibrated antenna range. Extended test reports with E-plane, H-plane, and cross-polarization cuts are available on request.
