E05Control-link antennas

Provide the receiver’s radio-frequency interface.

Manufacturers & products

A control antenna must match the receiver band and input connector. Carbon plates, batteries, wiring and propeller clearance constrain its useful placement.

American sourcing options appear first. A U.S. company or distributor label does not establish U.S. manufacturing. The origin notes identify the specific evidence and any limits.

manufacturer

Lumenier

SINDRA Gemini 915 MHz / 2.4 GHz

Dual-band linear control-link antenna with U.FL and multiple cable lengths. [4][1]

U.S. company

Lumenier identifies Sarasota, Florida headquarters and a Shenzhen facility. The cited US production claim concerns ARORA drones, not these antenna SKUs; antenna manufacturing origin is unverified. [4][1]

Program / application

Dual-band control alternative; the 153 mm radiator needs deliberate 5-inch clearance [4][1]

Company location: Sarasota, Florida, USA

Online catalog / ordering

Official product page provides a catalog or inquiry route; verify current stock, revision, firmware and connectors before ordering.

Product scope & qualifications
  • Do not assume every receiver can use both bands; match its hardware and RF ports.

manufacturer

TrueRC Canada

D-POLE 2.4 MKII

Protected linear dipole with locking U.FL interface. [5][2]

International supplier

TrueRC states all its antennas are designed and manufactured in Quebec, Canada. This is a manufacturer statement, not an independent lot certificate. [5][2]

Program / application

5-inch 2.4 GHz control-link candidate [5][2]

Published manufacturing site: Quebec, Canada

Online catalog / ordering

Official product page provides a catalog or inquiry route; verify current stock, revision, firmware and connectors before ordering.

manufacturer

RadioMaster

RP1 external T antenna

External antenna supplied with the RP1 receiver. [3]

U.S. connection unverified

The reviewed listing does not establish corporate domicile or manufacturing country; no US origin is claimed. [3]

Program / application

Bundled 2.4 GHz receiver antenna; confirm the replacement SKU with the manufacturer [3]

Manufacturer inquiry

The cited receiver listing includes an antenna; it does not establish a separately orderable replacement SKU. Request the correct connector/cable replacement.

What remains unverified

  • The D-POLE page labels a linear antenna gain in dBic; that inconsistent gain unit is intentionally omitted.
  • The SINDRA long-cable selector and specification text disagree on 200 versus 220 mm; the example uses the consistent 50 mm variant.
  • Standalone RadioMaster replacement-antenna part identification remains to be confirmed.

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

  • RF band

    Match the receiver's actual RF front end; dual-band branding is not universal compatibility.

  • Polarization

    Keep the intended linear orientation and consider the transmitter antenna's orientation.

  • Diversity placement

    Separate or orient antennas according to the receiver architecture and installation guidance.

  • Radiator clearance

    Keep active antenna sections away from conductive carbon and battery shielding.

  • Connector

    Check connector family, retention and pigtail strain relief.

  • Cable loss

    Extra cable length adds loss and can become a crash snag.

  • Mechanical envelope · mm

    Account for the radiator span, not just cable length or connector size.

  • Mass and origin · g

    Compare exact cable variants and SKU-specific provenance.

Selection & integration notes
  • A control antenna is not a substitute for a 5.8 GHz video antenna.
  • Check the swept propeller envelope and cable strain before selecting a longer antenna.
  • Replace damaged coax or loose connectors with the manufacturer's correct assembly.
