Connectors for Drones — Amass, N-type, SMA Power and Antenna Connectors
In any unmanned system, the connector is the point where losses most often occur: contact resistance in the power line eats into battery capacity, while a poor antenna connection shortens signal range. Astreia Tactical carries two logically distinct groups of connectors that cover these needs. For power lines — Amass connectors, a leading manufacturer of connectors for RC and FPV equipment: the lineup is built around gold-plated brass contacts in a heat-resistant nylon housing that withstands heating under sustained current load. For signal lines — connectors in the N-type, SMA, QMA, and TNC standards, used to connect antennas, signal boosters, and repeaters. The choice between them isn't a matter of preference but of compatibility: the power connector type is determined by operating current and battery format, while the antenna connector type is determined by the port on the receiver or booster and the diameter of the cable being used.
A connector rarely works as a standalone element — a complete solution is always made up of several compatible components. For a power line, that means matching wire gauge (most often silicone cable in an AWG format rated for the connector's stated current), plus dust and moisture protective caps where needed. For an antenna line, that means coaxial cable with proper shielding and, if required, a pigtail adapter between standards (for example, QMA–SMA–N-type) when the equipment and antenna use different ports. The key point when assembling a set is not to mix male and female connectors from different series, and to check that the power connector's rated current matches the battery's actual load — not just the wire's carrying capacity.
Technical Advantages of Connectors in This Category
- Gold-plated contacts — Amass power connectors use gold-plated brass contacts that reduce transition resistance and energy loss at the connection point.
- Heat-resistant housing — nylon housings on power connectors are rated to withstand heating under sustained current load without deforming.
- Antenna port standards — N-type, SMA, QMA, and TNC cover most receivers, boosters, and repeaters used in FPV systems.
- Signal-line shielding — coaxial cables for these connectors offer a high level of shielding, minimizing interference on the signal.
- Dust and moisture protection — protective caps are available for both power and antenna connectors, extending connection life during field use.
- Cross-standard compatibility — pigtail adapters between QMA, SMA, and N-type allow an antenna or booster to connect to equipment with a different port type without replacing the device itself.
- Current headroom — certain Amass power connector series, such as the AS150, are rated for high current loads suited to large-capacity batteries.
- Genuine product — power connectors are sold as genuine Amass products, not unbranded equivalents of unknown origin.
Connectors from Astreia Tactical
Astreia Tactical supplies connectors that match their stated technical parameters — current rating for power connectors and impedance for antenna connectors. Before shipping, each order is checked for completeness and accuracy, and consultants are available to help select the correct male-female pair or adapter for specific equipment — from an Amass-based battery connector to an antenna system with an N-type, SMA, or QMA port. This approach makes it possible to assemble a compatible power or signal chain without unnecessary trial and error or repeat orders.
