The Hollyland Mushroom Antenna (Model: HL-ATN03) is an official OEM high-performance replacement antenna custom-engineered for Hollyland’s flagship Mars and Cosmo series wireless video transmission systems.

Known on set for its distinctive domed "mushroom" capsule shape, this antenna utilizes advanced circular polarization. It is the go-to solution for camera teams operating dynamic handheld setups, Steadicams, or complex motorized gimbals where standard straight-line antennas frequently drop frames or lose connectivity due to extreme camera tilting and rapid multi-angle movements.

 

Core RF & Operational Features

  • Circularly Polarized Wave Architecture: Unlike standard flat "paddle" or thin whip antennas that use linear polarization, the Mushroom antenna broadcasts an omnidirectional, spiraling RF wave. This mitigates "cross-polarization attenuation"—the abrupt signal drop that occurs when a camera twists or banks out of direct vertical alignment with the video village receiver.

  • Broadband 5 GHz Optimization: Built to operate cleanly within the 5.0 GHz to 5.9 GHz frequency range. It provides a reliable 2.5dBi gain, ensuring low-latency 4K and HD video feeds slice right through heavy on-set Wi-Fi interference.

  • Impact-Resistant Domed Cap: The delicate internal antenna elements are entirely enclosed inside a thick, ruggedized injection-molded capsule shell. This reinforced design easily withstands accidental bumps, equipment drops, or being jostled during tight camera handoffs.

  • Flexible Extension Stem & RP-SMA Lock: Features a robust, flexible lower neck that absorbs mechanical strain, preventing damage to the unit’s connector. It attaches via a gold-plated Reverse Polarity SMA (RP-SMA) internal female thread to ensure a lossless, secure physical mount.

System Interoperability

This performance-tuned broadcast spare features universal standard threading calibrated for Hollyland's 5 GHz video lines:

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

  • Cosmo Ecosystem: Seamlessly interfaces with Cosmo C1 wireless SDI/HDMI transmission packages.

Feature Specification
Official Model SKU HL-ATN03 (Part Family: Circularly Polarized Video Spares)
Antenna Profile Geometry Mushroom / Shielded Omnidirectional Capsule Form

On-Set RF Configuration Tip: To maximize transmission range and prevent latency glitches, always match your antenna polarization types on both ends of your wireless line. For optimal results, mount a pair of these dome-styled Mushroom antennas onto your on-camera transmitter, and pair them with matching circularly polarized antennas at video village. Mixing a circular capsule antenna on the camera with standard flat linear paddle antennas on your monitor can cut your system's effective transmission distance by up to 50 percent.

Definitely worth the read!
Format: Kindle
After taking a deep breath and taking in that wicked twist of an ending, I have finally composed myself. My first thought when I started this book was that I love Reyna's character. I was intrigued by her connection with her familiar and the Ruin that is plaguing her land. It came as no surprise that she took her sister's place in an attempt to protect her. When they reach the Air Court everything slows down. This is where it was iffy for me. First of all, I like multiple POV's in books however 7 is a bit much. It starts to interrupt the story line. I felt like I was finally making progress connecting with one character, then it was switched to another person. I felt they all had necessary or pertinent information but not necessarily were they all POV worthy. The only other thing that annoyed me was that Reyna constantly was " trapped." She would rush off without thinking, only to need rescuing. She is brilliant in a fight, but she really doesn't think through anything. Lorcan is amazing. I know he might be on the "bad" list, but his background is so interesting. Eislyn(Reyna's sister) is really so sweet, but calculating. I enjoyed her and Thane's dialogue. The author did an amazing job with the imagery in this book. Everything was so detailed it was easy to fall into the scene. I love unexpected twists and while part of the ending I expected, I wasn't expecting how it took place. All in all, I found it very entertaining and I am very invested in continuing this series. Favorite quotes: "The truth may be twisted but never false." "Who was she if she was not the enemy of the Air Court? What was her purpose of she no longer has that?" "In a war-torn land, love was always a lie."

Great Read!!! Great story!!!
Format: Kindle
The series is long, but Ms. Wolfhart does a fantastic job of weaving this tale while bringing so much to the characters. Surprises and plot twists along the way to keep you intrigued. There is some graphic sex, but is no way the focal point. Grammar was excellent (a rare find with a lot of self publishers) with only a few noted errors. I rarely give 4 stars, let alone 5.

Sadly, DNF
Format: Kindle
I read this thru KU. I LOVED the synopsis. And then I began reading... and it was a DNF at 68% after picking it up and putting it down several times because I really loved the main female character. *****SPOILERS***** Pros: The world is unique, intriguing and fun. The primary female character is bad-a** but not a b*tech or a mary sue. The primary female has depth. I really want to know what happens to her even tho it's been weeks and I don't remember her name. The villains to the point I read are pretty good -- an ever present threat of mysterious and possibly many culprits. Cons: Way, way too many points of view. I stopped counting at 7. It's the prime reason why I don't care about most of the characters or remember their names even when I like them. There's just too many points of view so almost none of the characters have enough book space for the author to properly develop them. This literally killed the book for me. Actually it killed my desire to read. For weeks. The main male is more villain than hero. He agreed to marry the main female then locks her up & eschews her for her sister, all while bad mouthing her as unfit to rule when he never spent any time with her getting to know her. He is actually unfit to rule as he is blind to the woes of his own kingdom and starts off a peace mission to secure a ceasefire through marriage by murdering an inn full of people in her country for no real reason. Plus, he constantly makes promises he does not keep. And it's gross of him to pine for the sister behind the main female's back. ***** As much as I really wanted to see what happened to the main female character, it wasn't enough for me to keep trying to slog thru this book. There was a lot of potential here that just fell short. Hence, 3 stars.

Fae Courts with High Intrigue
Format: Kindle
This book is one that just builds and builds and then surprises you to no end. You may think you know the villains and then you are jolted in another direction. Princess Reyna is a real gem, strong of character, a fierce fighter, and loyal to her family and kingdom. Just when you think she and Lorcan, well you know, the plot is flipped. Can't wait to see where this goes in book two.

Slow, sorry but good
Format: Kindle
This was a slow moving book. Lots of character pov chapters, lots of superfluous descriptions and endless courtly appearances stalled this book to start. Once you get into the heart of the story, it takes off. Before you know it the book is done. My favorite character is Reyna. She is so strong. She is true to herself. She gets into a lot of trouble with her headstrong ways but it's entertaining. I have high hopes for Lorcan. He is honorable to a fault. Thane had turned out to be better than I thought but i still don't like him. Eislin is useless. Great plot twists at the end. I'm looking forward too book 2.
