Adjustable helical antenna
I was wondering if it would be possible to have an adjustable helical antenna by cutting/separating each turn, let's say after the first 3 and using copper collets to snug fit each turn after that, giving you the ability to adjust your gain on the fly
Your thoughts Kyle |

Fpv noob
Hey Alex,
Im a Noob when it comes to FPV and i had a question that im sure there are 100 different answers too but i wanted your opinion since you seem to be the MAN. I want to put an fpv set up on my RC car and drive around my neighborhood with it. Maybe go out like 2 or 3 block away (1000 meters MAX but I live in a pretty populated city) so i was thinking of a 1.2ghz system, maybe like a 1500mW system that ive seen online and some type of directional antenna. Maybe something that can power through a couple house walls. If of course this is even possible. Thanks! -Dexter |

I'm not alex, but you can check my blog here on RCG (click on my name) and look what I did with my Summit on 1.3ghz.
Surface FPV is challenging but at least you can't crash |

Alex,
many thx for these wonderful tutorials... i learned a lot about antennas and vx/tx systems with the help of them. built versatile simple antennas that increased my systems functionality drastically.. i use both 2,4 and 1,2 ghz ststems, especially i am astonished about the performance of a little Moxon antenna simply built for my 200mw 1,2ghz system... i am using it on a robotic rover wandering along my big terrace and i can control it and watch video tx from inside, it penetrates through my numerous thick walls now... thx again for your hard work and wish you a crashless flying.... dincer |

How much power are you using again on your VTx Alex ?

I stumbled upon this thread, it kind of went to sleep but the prospect of reasonable range HDMI transmission is interesting: https://www.rcgroups.com/forums/show....php?t=2023808 I wonder if CP antennas will help increase the range. If we could do say like a 1000 feet or something, it would bring a whole new dimension to FPV. Off course, we will then need goggles that can do 1080P but it could be fun to fly off a big screen TV! |
