Hollyland Spares - Capsule Antenna (for Mars & Cosmos Series)

The Hollyland Capsule Antenna (Model: HL-ATN10) is an official OEM replacement and ultra-compact upgrade antenna engineered for several generations of Hollyland’s pro-grade wireless video transmitters, receivers, and transceiver monitors.

On highly active film sets, traditional paddle or whip antennas pose a constant rigging hazard—frequently snapping during fast-paced camera tracking, getting knocked out of alignment by actors, or tangling with nearby stabilizing cables. The capsule antenna eliminates these vulnerabilities entirely. By condensing the physical antenna structure down into a ultra-short "stubby" shell, this accessory delivers a ruggedized, snag-free wireless solution that keeps your camera package as streamlined as possible.

Core RF & Low-Profile Structural Features

• Zero-Snag Miniature Architecture: Shorter and more compact than bullet-style or paddle configurations, the capsule design fits almost completely flush against the transmitter's chassis. This reduced physical footprint makes it much easier to balance the wireless unit on automated 3-axis gimbals, inside vehicle dashboard rigs, or on compact handheld mirrorless cages.

• Impact-Armor Polycarbonate Build: The fragile internal copper RF elements are fully enclosed in a thick, injection-molded polycarbonate protective housing. This solid-state design easily shrugs off drops, bumps, and accidental impacts that would bend or destroy standard flexible antennas.

• Omnidirectional 360-Degree Radiation: Despite its micro size, the internal antenna engineering produces a uniform, spherical RF coverage zone. This ensures steady, low-latency transmission performance, minimizing signal dropouts when a camera operator pivots, cranes, or tilts the rig rapidly away from the receiver.

• Corrosion-Resistant RP-SMA Threading: Built with a precise Reverse Polarity SMA (RP-SMA) internal female thread. The high-tolerance brass connection establishes a rock-solid, wiggle-free physical mount onto your transmitter's RF posts, eliminating signal leakage.

System Interoperability

This universal replacement accessory is specifically tuned to operate cleanly within standard 5.1 GHz to 5.8 GHz video transmission bands, offering plug-and-play compatibility across several Hollyland lines:

• Mars Wireless Series: Direct mechanical match for the Mars 4K, Mars 400S Pro, and Mars 300 Pro wireless transmission systems.

• Wireless Monitor Units: Seamlessly interfaces with the Mars M1 and Mars M1 Enhanced wireless transceiver field monitors.

• Cosmo SDI/HDMI Series: Functions as a replacement or low-profile option for the Cosmo C1 broadcast system.

Technical Specifications Matrix

On-Set Wireless Rigging Best Practice: Because micro-profile capsule antennas sit very close to the metal body of your transmitter, they have slightly less physical clearance to push signals past structural blockages. For maximum transmission distance and clarity, avoid burying the unit inside a dense metal camera cage or directly against a large V-mount battery plate. Whenever possible, mount your wireless transmitter or transceiver monitor high up on your rig so these capsule antennas have a clear, uninterrupted line-of-sight toward the receiving video village.
