What Must Be Engineered Around the 3.7 m Reflector
Reflector diameter is only one part of a transportable SATCOM terminal. A usable project configuration also requires the feed, RF path, pointing arrangement, outdoor-unit load, electrical interfaces, transport limits and site conditions to be defined together.
OMT and Polarization Routing
Separates or combines orthogonal polarization paths where the feed architecture requires it.

Waveguide Filters
Adds frequency-selective functions where the receive or transmit chain requires channel separation or rejection.
View product →
Waveguide Diplexers
Combines or separates defined frequency paths within a specified feed-network architecture.

Where a Transportable 3.7 m Antenna Can Be Considered
The system is intended for stationary operation after deployment. It should not be described as an antenna for communication while the trailer is moving unless a separately engineered on-the-move system is specified.
Choose by Deployment Model, Not Diameter Alone
A transportable trailer platform, roof-mounted driveaway antenna, flyaway kit and fixed earth station solve different logistics problems. Compare the deployment method first, then confirm aperture, band and link requirements.
| System Type | Best Fit | Key Constraint to Check | Related Product |
|---|---|---|---|
| 3.7 m transportable trailer-mounted | Relocation between temporary operating sites with a larger reflector | Road envelope, site leveling, deployment clearance and project-specific RF configuration | Current system → |
| Vehicle roof-mounted driveaway | Faster vehicle-based relocation with smaller published aperture options | Roof load, stowed height, vehicle interface and axis/control configuration | 1.2/1.5/1.8/2.4 m driveaway → |
| Quick-deploy flyaway | Transport in cases and assembly away from a dedicated vehicle or trailer | Packed mass, case size, assembly method and allowable setup time | 1.8/2.4 m quick deploy → |
| Fixed prime-focus earth station | Permanent or long-term site where transportability is not required | Foundation/mount, installation access, wind design and long-term alignment | 3.7/4.5 m prime focus → |
| Fixed dual-reflector earth station | Permanent station requiring a dual-reflector antenna architecture | Feed architecture, pedestal, installation and approved RF specification | 3.7/4.5 m dual reflector → |
From Requirement Review to Approved Configuration
A transportable antenna should be quoted against a controlled requirement set. This prevents a mismatch between the RF link, feed system, outdoor units, pointing controls and trailer constraints.
Requirement Capture
Collect frequency ranges, link targets, satellite information, polarization, ODU details, transport limits, site conditions and required documents.
RF and Feed Definition
Define reflector-feed matching, polarization paths, component interfaces, filters/diplexers and transmit/receive equipment integration.
Mechanical and Control Review
Confirm stow/deploy geometry, leveling and stabilization, axis movement, controller requirements, power and cable routing.
Quotation and Specification Approval
Agree the supply boundary, drawings, datasheet values, accessories, test scope, packing, delivery terms and exclusions before order.
Integration and Verification
Apply the agreed inspection and measurement plan to the supplied antenna, feed system and associated microwave components.
Satellite and service: satellite name/orbital position, teleport or field service, planned carrier and modem.
Frequency: exact receive and transmit ranges, channel bandwidth and required waveguide band.
RF targets: gain/G/T/EIRP, VSWR, isolation, cross-polarization and radiation-pattern requirements.
Feed path: polarization, ports, OMT/polarizer, filters/diplexer, flange and interface drawings.
Outdoor units: BUC/HPA/LNB/LNA models, dimensions, mass, power, cooling and mounting requirements.
Pointing: manual, motorized or automatic acquisition; tracking need; control and telemetry interface.
Transport: destination country, road limits, towing vehicle, maximum stowed envelope and mass.
Environment: wind, temperature, rain/dust, altitude, terrain and deployment surface.
Power: supply voltage/frequency, generator or mains source, connector and grounding requirements.
Deliverables: drawings, manuals, test report, packing list, spares, training and acceptance requirements.

3.7 m Transportable Antenna Questions
Is this a 4.5 m vehicle-mounted antenna?+
The live product title and published product image identify a 3.7 Meter Transportable Trailer Mounted Antenna. The final quotation should use the approved product name and drawing rather than relying on the older URL wording.
Which frequency bands does this model support?+
The current product record does not publish a model-specific band or frequency range. Provide the exact receive and transmit ranges so the reflector-feed combination, interfaces and associated microwave components can be reviewed.
Does the antenna operate while the trailer is moving?+
This product is described as transportable and deployable for field operation. It should be treated as a stationary terminal after setup unless an approved specification explicitly includes communication on the move.
Are gain, wind speed and setup time available?+
Those values are not published on the current product record. They should be stated in the model datasheet or approved project specification after the feed, control, trailer and environmental configuration is fixed.
Can Dolph provide the feed and waveguide components?+
Dolph’s published scope includes microwave feedhorns, antenna feeder networks, OMTs, filters, diplexers, polarizers and waveguide components. The supplied items and performance values must be listed in the project quotation.
Is the complete antenna ISO certified?+
The published ISO 9001:2015 certificate states a scope covering waveguide component design, manufacture and sale. It is a quality-management-system certificate and should not be described as certification of the complete trailer-mounted antenna.
What documents should be approved before production?+
At minimum, approve the product specification, RF block diagram, interface-control information, deployed and stowed drawings, supply boundary, accessory list, test/acceptance scope, packing method and delivery documentation.
