QUOTE(zeroglyph @ May 27 2020, 06:20 PM) Haven't had a decent outdoor flight time since January. Had to sneak a flight. You can see the shaky controls Ah! nice to be out again to fly. I still wait until everything is clear, still CMCO period.    |

i have a question. is there any actual difference for receiver and transmitter antenna? if you notice, some FPV antenna are sold in pairs, specifically being labelled as TX and RX. is this a real thing? my understanding of wireless transmission think that it's NOT. antennas just amplify the signal, it's just some wires in specific arrangement. it doesn't matter if you use it for TX or RX.
what do you guys think? it's just a marketing scam or it's a real thing? |

If you're talking about that mushroom shape antenna with dome shape labelled TX and RX on top then there are actual differences. Inside the dome of RX antenna there is a SKEW PLANAR 4x lobe antenna structure that use to catch/received 'angled' signal. While in TX inside the dome have a CLOVER LEAF 3x lobe antenna structure that use to transmit angular signal in various direction ideally for transmitter. This antenna ideal for models that fly and tilt various direction in very obstructing environment.what do you guys think? it's just a marketing scam or it's a real thing? |

these are the pairs that i have.
rx is a 4 lobe rhcp skew planar and tx is a 3 lobe rhcp cloverleaf. just found some extra info: QUOTE The Skew-Planar Wheel is best suited for the receiver, but will work pretty well as a transmitter antenna as well. It has an excellent radiation pattern and very low gain. The reverse polarization rejection pattern is much better and more uniform than the Cloverleaf, making it excellent for the receiving end. The lowest SWR possible is 1.2. Gain: ~1dBi Lowest SWR possible: 1.2 Directionality: Omnidirectional Difficulty to make: High Best suited for: Video receiver so it can be used as either but there are best suited conditions. i have a 4 lobe skew-planar antennas on my other quads(as TX). so in conclusion, the TX/RX pair type of antenna is not a scam after all. it's just best to use them in that particular pair configuration. myth busted!

this why learning to fly with GPS is dangerous. "commercial" operators are ruining the hobby  . as always, i blame DJI and their drone enthusiast community as well.  |

I have seen bird attacking drone. Try dodging that even with FPV. The only way stopping drone from coming down fast when there is a failure, is parachute.
