Flipper Zero custom subghz antenna reaches 660 yards - CC1101 Module Antenna bake-off

In this video Maya and I test the range of the Flipper Zero to read a 433 Mhz weather gauge - using the internal antenna, two common stock CC1101 module antennas and two antennas customized for 433 Mhz.
Spoiler: the custom quarter-wave ground plane antenna is the best by far, reading the weather sensor at 661 yards.

Antennas should be in our store starting 7/17/2023: www.tindie.com...

Hello Kevin, nice informative video, thanks! For the metric viewers out there, I've added your candies in meters. Cheers from across the pond! Flipper Internal Antenna - 23 yards (21 meters) External Monopole Whip Antenna - 46 yards (42 meters) 433Mhz Coil Antenna - 49 yards (45 meters) Quarter Wave Monopole - 145 yards (133 meters) Quarter Wave Ground Plane - 661 yards (604 meters)

Looking forward to your store restocking.

In the city this range is drastically reduced

But these things have to be done! I am biased being a radio ham.... Experiment away

[@TechnologistAtWork]

@@hamradiofun5527 I understand, but a more practical test would be somewhere like a parking lot where there's plenty of noise.

[@hamradiofun5527]

@@TechnologistAtWork noise that can be heard or noise as in RF?

[@BallisticSuperiority]

​@@hamradiofun5527probably both. But I believe the variable that is mostly worth mentioning is RF noise. The 433mhz band is VERY busy the closer to people we get and where they live/commute/work. Lots of gadgets utilizing the bands for personal and commercial uses.

[@BallisticSuperiority]

You could implement some homebrew filtering and zero in on the desired signal to drown out some of the other RF noise. Although malfunctioning devices could saturate beyond their bandwith

Now that’s my kind of party 🤣 Great video guys

[@TNTSecurite]

Hey Kevin what hardware did you used for the antenna ? Like the connectors ? How it's been connected to the antenna.

[@BallisticSuperiority]

Came here from tindie. That really fucking impressive! How about TX? How does she perform when you put some power to her?

[@BallisticSuperiority]

Edit.. only 2 mins into the video. Just noticed it is almost 25 mins long..

[@bi0s1337]

Sorry for the dumb question but is also for sending or only for receiving? Greeting ;)

[@temno]

hello from Russia ;)

[@paranoidzkitszo]

Why you no ship to Canada? Antennas aren't banned.....

[@itzuleanu]

use a amplifier like AB-IOT433MHZ lora

[@SPUTNIK6996]

Tesla charging ports never stood a chance

[@mr.s1961]

Well said like the script kiddie you are. Because that will be all you use it for 🤣🤣

[@josephsaucedo8691]

If you were to take that antenna that's sending on the porch sending the signal and then get a old satlight dish and mount the antenna facing the dish basically bounce the signal off of the old dish. Would be interesting to see how much further it can go.🤔 At the same time I don't know how technically legal it is or should I say it isn't just because there are law's on how far certain signals can be sent and amplified. Unfortunately Wich doesn't make any sense to me because lawinforcment and military equipment isn't limited in radio signal ranges go figure 🙄📡🇺🇸👍✌️💯
