2X range hack for the VAS 2.4GHz Diamond antenna
Вставка

- This simple trick can double your control range when using the VAS diamond antenna. Be mindful that it is simply directing more energy forward at the expense of coverage to the rear and sides. The wire can be placed anywhere on the rear half of the hexagonal part of the antenna.

When you turn the antenna around we refer to that as Front to Back ratio. You don't want a large lobe off the back. You want that energy going forward creating the largest lobe. When FPV came around after flying RC Airplanes for nearly 42 years I found it fascinating that the average guy could apply Amateur Radio Television to RC aircraft. Everything got small so the payload was small. In the 90s we were flying full size F-86 Sabres as drone targets at White Sands Missile Range in New Mexico. Complete with TV Cameras, large servos and a ground station in a large van. Antenna Theory never gets boring and seeing it presented in a simulated field range test is the best teaching tool! I commend you for taking the time to make this video!
how could anyone give Alex anything but a thumbs up for ANYTHING he does given how much he's brought to the hobby? What a world...
I think hate is mostly envy. When you are successful in life whether it is getting ahead or just helping others, there will people who simply hate you out of envy.
AWESOME, I just got one for the holidays. Keep being awesome ..
Awesome man!!! Always working!
Modded my DX8 with a diamond. Now I can fly in a wifi saturated neighborhood without signal dropouts and Spektrums ridiculous short range telemetry works 3x the distance. Amazing antenna!
Thinkin bout puttin a couple of those little guys on a 3dr solo(drone side) Since everyone loves em they should work fine. Already have a VAS helical on the tx and it works great
Very interesting excellent 👍👍👍 👍👏👏👏 👏
Brilliant!! Does this work with a regular moxon antenna too?
I love the vas diamond it's way better than the stock antenna, I wonder would this work on a tbs diamond and if so how long and thick of gauge wire. I know what I'm doing tomorrow giving this a try as always I love the info videos please keep the coming.
A side question unrelated would a Vas switchblade work on a 2.4ghz transmitter stock antenna like the Taranis x9d.
TheAfroengineer he did a similar video with the TBS diamond antenna last week I think it was.
@@Dav2112- I did this the day before.
Does this apply to your original 2.4 folded dipole antenna I sometimes use when not using crossfire diamond.
Can anyone recommend a good 2.4 ghz tx / receiver combo? The FuriousFPV combo is sold out everywhere I look and I can't find any alternatives... Only TBS makes tx units, but no receivers for some reason...
Are you putting this on the plane or the controller? Would this work on drones as well? TIA...nice vid
THis goes on the controller. It will work for planes drones, and even WiFi antennas.
Thanks. I have a 2.4Ghz rubber duck on the drone. Will this combination work well then? Right now I'm using the stock 2.4Ghz omni dipole that came with the controller but want to put something better on it like what you have in the video. Appreciate the help.
No free lunch 👍
*On the aggregate level
Can I get the 2.4Ghz Diamond anywhere in the EU?
How about using this on mavic 2 or pepper box would it work ?
can you share a DIY version of this antenna?
So what is the effect of the radio electronics plus your body and who knows whatever else out in the field?
It is very hard to model... but you can bet it is almost not what you would think. The only thing you can do is set up for the best possible parameters and hope the effects you didn't account for are minimal.
Since the electrical tape is non conducive does that affect the antenna in any way? I know tpu and certain plastics around the active part of the antenna can negatively affect the performance ? Also, am i affecting the antennas performance if i put heat shrink on it?
In the amateur radio world we use plastic insulators in aluminum booms to hold elements in place. This isolates the elements from the boom. So the plastic has no effect.
JD Dupuy thanks for the clarification mate
Let me clarify this point: using insulation on the wire can change the length needed to make this work. Thus, I would use a length of wire 2-3/8" if the wire you are using has insulation.
Awesome! Maybe the next version can have a handy through-hole in the plastic?
I own this antenna and I have one question isn't the point of the diamond antenna to be very omnidirectional
Yes, of course. This is just a simple mod for those who want to venture into longer range flights without having to buy a new antenna for it.
what if i have 4awg? still work? what was the total gain? 9db?
Longer range 2.4ghz think I'd like to just run a 2.4ghz pepperbox 😉😉
Surely if this is attatched to your tx you will never get the 7db increase because you will be in close proximity to the antenna at all times. In your video it drops to about 5 so the rang won't be doubled
Real-World results will vary between 40% increase in range to 200% increase due to the effect of the ground which the pilot is standing on.
Do you have a link for one of those antenna for the xlite?
I have u.fl, RPSMA and SMA versions. If the Xlite has any of those connectors these will work.
X-Lite uses RP-SMA. Just make sure to switch the antenna from Internal to External in the menu.
What would be the wire dimensions for 900Khz (TBS/r9) Diamond?
6" exactly. I did a video on this as well.
@@CAGreve1231 Oh thanks a lot! I'll look for that video :)
Can I use that VAS transmitter antenna on my Jumper T16?
Absolutely! However, we have one with that jumper built-in called the "Shapeshifter" which allows you to turn it off and on with a small switch.
I already bought the VAS 2.4Ghz Diamond SMA.
@@neilfpv How is that going for you? I have also bought the SMA for my Jumper and waiting for it via mail
It's awesome! I never had failsafes anymore. I also changed the way receiver antenna was mounted on the quad. It's letter V and pointing to sky. However, I switched to Crossfire micro because I was curious. I think it's better than my XM+
All I have is 18 gauge, I wonder if that will work ?
