E04Telemetry & command antennas

Radiate and receive the spacecraft control link.

Manufacturers & products

Command and telemetry antennas prioritize reliable coverage and link margin across mission attitudes. Passive patches, deployable VHF/UHF elements and antenna modules with integrated RF electronics should be compared separately.

These are sourcing candidates, not a confirmed Starlink supply chain.

Anywaves

S-band and Ka-band TT&C antennas

Standard and compact spacecraft TT&C antenna lines provide defined polarization and coverage options, with engineering and flight models selected for the mission acceptance process. [2][1]

Published manufacturing site: France

Manufacturer inquiry

Request a technical quotation through the manufacturer; current configuration and availability require confirmation.

Product scope & qualifications

Select current revision and requested polarization; older portfolio values may differ from the latest mechanical drawing.

EnduroSat

S-band wideband/commercial/ISM; UHF antennas

Spacecraft antenna offerings include several S-band band-coverage variants and deployable UHF hardware alongside separate payload-downlink and navigation antennas. [12][7]

Company location: Sofia, Bulgaria

Manufacturer inquiry

Request a technical quotation through the manufacturer; current configuration and availability require confirmation.

Product scope & qualifications

Specify the exact S-band variant; ISM and commercial listings do not prove coverage of both TT&C sub-bands.

SAS-2

A passive circularly polarized S-band spacecraft patch spans distinct command and telemetry sub-bands with public band-dependent gain and beamwidth values. [13][11]

Company location: Aalborg, Denmark

Manufacturer inquiry

Request a technical quotation through the manufacturer; current configuration and availability require confirmation.

Product scope & qualifications

Antenna is not the SRS radio; matching, harness loss and spacecraft installation still need analysis.

NanoCom ANT2150-DUP and antenna modules

An integrated antenna/front-end family combines radiation hardware with RF electronics in selected variants, offering a different procurement boundary from a passive patch. [14][15][6]

Company location: Aalborg, Denmark

Manufacturer inquiry

Request a technical quotation through the manufacturer; current configuration and availability require confirmation.

Product scope & qualifications

ANT2150-DUP includes PA/LNA and duplex filtering; ANT2150-ISL uses a different link arrangement.

Deployable VHF/UHF antenna systems

Deployable antenna products accommodate compact spacecraft stowage and extend VHF/UHF elements after release, with configuration-dependent mass and band selection. [9][16][8]

Company location: Delft, Netherlands

Manufacturer inquiry

Request a technical quotation through the manufacturer; current configuration and availability require confirmation.

Product scope & qualifications

Deployment mechanism, element configuration and ground plane must match the spacecraft.

PULSAR-SANT

Compact S-band transmitter antenna variants are part of the Pulsar communication product family and can support telemetry/downlink paths when their band matches the mission. [19][17][18]

Manufacturer inquiry

Request a technical quotation through the manufacturer; current configuration and availability require confirmation.

Product scope & qualifications

SANT-C/SANT-A are transmitter-band examples; the published bands do not establish 2,025–2,110 MHz telecommand receive coverage.

S-band patch antennas

Space S-band patch antennas can be supplied with the vendor’s radio architecture, while the end-to-end system also includes separately procured ground equipment. [10]

Company location: Berlin, Germany

Manufacturer inquiry

Request a technical quotation through the manufacturer; current configuration and availability require confirmation.

Product scope & qualifications

Confirm a specific flight antenna, polarization and uplink/downlink matching; a system brochure is not a full antenna ICD.

Miniature S-band CubeSat and custom spacecraft antennas

Miniature and custom antenna designs address spacecraft communication accommodation, with manufacturer engineering support for mission-specific mounting and radiation-pattern requirements. [20]

Company location: Bedford, New Hampshire, United States

Custom program inquiry

Request a technical quotation through the manufacturer; current configuration and availability require confirmation.

Product scope & qualifications

Select the spacecraft product and environmental acceptance, rather than assuming launch-vehicle antenna heritage covers all space missions.

Frontgrade

Custom space VHF/UHF and patch antennas

Space antenna engineering covers low-gain and printed radiating structures as well as larger apertures, providing an option for spacecraft-specific command/telemetry coverage problems. [5]

Company location: Colorado Springs, Colorado, United States

Custom program inquiry

Request a technical quotation through the manufacturer; current configuration and availability require confirmation.

Product scope & qualifications

No catalogue pattern or universal TT&C band coverage is assumed; requirements define the configuration.

Space S-band feed/antenna families

Aerospace antenna and feed-chain products provide custom polarization and RF interfaces for spacecraft links, with exact S-band configuration determined during mission design. [4]

Custom program inquiry

Request a technical quotation through the manufacturer; current configuration and availability require confirmation.

Product scope & qualifications

Request the radiation pattern and TT&C uplink/downlink coverage; not every aerospace feed is a broad-coverage command antenna.

View product & inquiry route

What remains unverified

Antenna gain without the full installed radiation pattern cannot establish spacecraft coverage.
Several sources have old public datasheets alongside current catalogue pages; dates/revision limits are retained.
No published standard antenna establishes compatibility with the illustrative satellite without mounting, EMC and link-budget analysis.

Where it comes from

A company address is shown separately from a published factory location. Request the manufacturing site and lot traceability for the exact part when sourcing.

What to compare

Link bands and polarization · MHz / dB
Verify separate uplink/downlink coverage, handedness, axial ratio and antenna orientation.
Coverage versus gain · dBi / degrees
Examine full-sphere radiation patterns, spacecraft blockage and edge-of-coverage gain rather than peak gain alone.
RF matching and isolation
Check return loss/VSWR, cable loss, duplexer requirements and transmit-to-receive coupling.
Delivered electronics
Separate passive antenna from an integrated PA/LNA/filter module; mass and DC power depend on this boundary.
Mounting and accommodation · mm / g
Include connector height, ground-plane requirements, thermal finish and keep-out zones.
Deployment reliability
For deployables, assess redundancy, release power, deployed length, inhibit logic and confirmation sensing.
RF power handling · W
Check average/peak transmit power, duty cycle and thermal/vacuum qualification.
Environment and acceptance
Compare qualification versus operational limits, materials/outgassing, vibration and unit acceptance evidence.

Selection & integration notes

A mission may need multiple antennas for different spacecraft attitudes; no single patch should be assumed to provide unobstructed all-sky coverage.
Commercial, ISM and licensed-space S-band variants cover different frequencies; physical resemblance does not make them interchangeable.
A high-gain data-downlink antenna and a broad-coverage command antenna serve different jobs.
For passive hardware, zero electrical consumption does not mean zero system power: the connected radio/amplifier remains a separate budget.
