RHCP vs LHCP: The Circular Polarization Deep Dive for FPV Pilots
Understanding Circular Polarization: More Than Just a Technical Detail
Circular polarization isn't just a fancy term—it's the secret sauce that can make or break your FPV signal performance. Let's break down the differences between Right-Hand Circular Polarization (RHCP) and Left-Hand Circular Polarization (LHCP).
The Spinning Signal: How Circular Polarization Works
Imagine a signal that's not just moving forward, but spinning like a corkscrew through the air:
- RHCP spins clockwise when viewed from the transmission point
- LHCP spins counterclockwise when viewed from the transmission point
- Think of it like a spiral staircase, but for electromagnetic waves
Why Matching Matters
The golden rule of circular polarization:
- Transmitter (TX) and Receiver (RX) MUST have the same polarization
- RHCP TX = RHCP RX
- LHCP TX = LHCP RX
- Mismatched polarization can cause up to 20-30 dB signal loss
Real-World Performance Implications
Signal Rejection Benefits
- Helps reduce multipath interference
- Minimizes signal reflections from surfaces
- Provides more consistent performance in complex environments
Orientation Flexibility
- Allows for more robust signal in dynamic flying conditions
- Less sensitive to antenna angle changes
- Helps maintain link integrity during aggressive maneuvers
Practical Considerations
When to Choose RHCP or LHCP?
- No inherent performance difference between RHCP and LHCP
- Choose based on:
- Existing equipment in your setup
- Matching with your flying buddies' gear
- Personal preference (once you standardize)
Pro Tip: Consistency is key. Once you choose a polarization for your system, stick with it across all your equipment.
Common Misconceptions
- RHCP is not "better" than LHCP
- It's not about signal strength, but signal matching
- Think of it like a special handshake - it only works when both sides match
Why Antenna Matching is Vital for 5.8 GHz Systems
In 5.8 GHz wireless systems, antenna matching is critical for achieving optimal performance. When antennas are tuned to the same frequency range, they work together seamlessly, delivering strong signals, fewer disruptions, and reliable operation. Mismatched antennas, however, can cause a range of issues that undermine your system.
The Impact of Mismatched Antennas
Imagine two antennas:
-
Antenna A: Works perfectly at 5640 MHz with a VSWR of 1.1 (excellent). But at 5900 MHz, its VSWR rises to 2.5, causing significant signal reflection.
-
Antenna B: Performs flawlessly at 5900 MHz with a VSWR of 1.1, but at 5640 MHz, its VSWR increases to 2, leading to similar problems.
This mismatch leads to:
-
Signal Reflection: High VSWR means the antenna reflects power back to the transmitter, weakening your signal and reducing range.
-
Transmitter Overload: The reflected power can overheat and damage the transmitter over time, much like overloading an engine.
-
Inconsistent Performance: Operating across a range of frequencies (e.g., 5640–5900 MHz) becomes unreliable, with performance varying significantly depending on the frequency used.
The Importance of Axial Ratio
The axial ratio measures how well an antenna maintains circular polarization. A low axial ratio (close to 1 or 0 dB) is ideal, while a high axial ratio leads to:
-
Weaker Signals: The antenna becomes less efficient at transmitting or receiving signals.
-
Increased Interference: In environments with reflections, a poor axial ratio worsens interference.
-
Polarization Mismatch: If the antennas at both ends of the link have different axial ratios, communication becomes less effective.
Why Matching Antennas is the Best Solution
By choosing antennas tuned to the same frequency range (e.g., 5640–5900 MHz), you ensure:
-
Consistent Low VSWR: The antennas perform efficiently across the entire range, with minimal signal reflection.
-
Optimal Axial Ratio: The antennas maintain excellent circular polarization, reducing interference and improving signal quality.
-
Transmitter Protection: Less reflected power means your transmitter stays cool and operates efficiently.
-
Cost Savings: You avoid the extra time and expense of tuning or replacing mismatched antennas.
As an antenna manufacturer, we deliver precision-tuned antennas tailored to your exact needs, ensuring your system runs smoothly and reliably. No mismatches, no compromises—just exceptional performance.

Antennes reçu bonne qualité dans l ensemble je vais les essayer avec mon Google v2 merci à vous pour les bonbons merci encore
Très bonnes antennes, je viens de passer du combo de base ev800dm avec lolipop4+ sur mon drone a un pack complet d antennes de Prodrone (ev800dm + drone)... Incomparable, le pénétration est juste bcp plus puissante, quasiment zéro glitch ou avant je n'allais même plus car je perdais la réception. Ne cherchez plus, elle sont excellentes et moins chères que ce que l'ont trouve habituellement. Dernier détail, 4 antennes achetées et en plus ils mont offert une antenne, tout ca pour juste 50 €. Je ne volerais a l'avenir qu'avec leur antennes.
great quality, antenna never tested yet though. got free pagoda 5.8ghz antenna and a chocolate. thank you
Très bon montage sur les Cobra X (SMA angle). Pas trop encombrantes, très bonne réception, belle manufacture. Du coup j'ai aussi commandé une Pagoda et une Cloverleaf RX. Merci Prodrone.
Impressive quality, excellent antenna for your RX, thanks a lot to team of Prodrone.
Very good antena for middle range flying. For longer range better use helical antennas.
ho preso queste antenne 1 anno fa ne avevo sentito parlare molto bene..confermo che sono fantastiche e in piu prodrone te le manda con un adesivo con su scritte le frequenze su cui lavora meglio quell'antenna...soddisfatissimo tanto che le ho messe su tutti i miei droni e ne ho parecchi qualita' prezzo ottima
Réception antenne excellente, très bonne qualité montage sur lunettes eachine EV300Oled
Cette antenne est le must. Tous les pilotes devraient en avoir au moins une. Rien de mieux. Elle est au top
Frequency fine 5745
