Phantom 2 Vision + range

Hi Z10M does that work for fpv (wireless) as well

Yes it does. There is already a thread about building your own reflector antennas if you search for it. I made reflectors for both the 2.4 gHz and 5.8 gHz signals (literally took 5 mins). In addition to using either of the 2 available booster apps, my range for both control and FPV went from ~1800-2000 ft stock to ~2400-2800 with booster apps to over 4000 ft with booster apps/reflectors.
 
Found this image in the tutorial on making the code can disc. It seems to me that instead of aligning the antenna parallel to the landing gear, pointing its tip towards the sky and let the custom made disc to reflect the backward wave forward be a bit more sense.... am I getting the wrong idea of what "parallel" meant at first place....

Am I getting it right in my hand sketch? Sorry for dragging it so long.... I want to get it right...

Coke can or no coke can that is the way u want to point your antenna.

Thanks.. I finally understand now... I was always under an impression that the tip is the strongest signal... especially when DJI also draw it this way :eek:

My bad, should have read the text above it as well in page 25..

Thanks

Is there a template I can print and cut out for the cardboard section to ensure I have the most optimal radius for the coke can by any chance?

I've seen various diagrams with complex numbers indicating the correct radius, but I'd like something that can be just easily copied/printed without needing a degree in RF tech to work out.

Thanks.
 
The diagram has changed in the version 1.2 Phantom 2 Vision+ manual. Makes more sense now.

I highly recommend the following mods from FPVLR. I've done them and have amazing range now:

5.8 GHZ 4.25 TURNS FATSHARK SERIES HELIX: Replaces small white antenna on the TX
http://fpvlr.com/shop/index.php?route=p ... duct_id=63

LHCP 2.4GHZ HALF SPHERE HELIX 9 DBI: Add on to the wifi repeater box
http://fpvlr.com/shop/index.php?route=p ... duct_id=54

With just those, I've gotten about 3000 ft in a dense urban environment. I am going to add 4 of these guys on to the bird to get even further away: http://fpvlr.com/shop/index.php?route=p ... duct_id=56

I really cannot recommend their work enough. It is high quality, and well worth the price.

It says frequency in Mhz. Do we need to enter that value? If so what should it be? Also, which plug do we select?

Same with the LHCP.

Thank you in advance because these things are very new to some of us.

#9 had a link to a dropbox folder where you could download a template

Here is one I found

Gonna try reflector mod until I get my kit from tony at FPVLR. Curious to see if there is a difference...

It seems yours are more easier to follow.

Can anyone comment on the statement.... Is it a lot? or just normal?

"If printed at the download size you will see about 9 dBi of gain. If you double the size of the image before you print it you will see about 12 dBi of gain."

Tony is VERY responsive... so if you leave it blank, or better yet, ask him, he will make sure you get the right stuff.
 
May I ask if I do it this this way, will the Wi-Fi from the phone affect the radio? I know one is 5.8 radio another is 2.4, but will they interfere each other at that close distance?



Apart from the missing aluminium foil around the curve reflector, may i ask is there anything that doesn't make sense?

I wouldn't put the phone in front of the reflector like that ... see if you can swivel things around and have the phone behind like others are doing... bound to have a negative effect on your results... :ugeek:
i have problems with getting the phone out of the way and keep antenna straight up... just wondering, if I follow what Z10m did, is it still Ok? It's seems the reflection surface will try to reflect waves towards the ground....
