Let the fun begin!

You are on the edge of a very deep dark pit! The fun turns to obsession.... This will start to take over your life :lol:

Not all black Pearl are rp-sma, mine is sma.

Yes, you have to be careful. Firstpersonview.co.uk only sell SMA versions.
Thank you everyone. DroneShack.co.uk, my local supplier here in Northern Ireland, tell me theirs is definitely SMA. Need to order my Horizon antennas now. I get my Phantom 2 tomorrow :D Let the fun begin!


Yep, the fun will definately begin when you try and go much further than 1000m with it !! :D

Why would you go to the expence of buying a BP alongside an Uno receiver as these receivers are ment to be far superior to the in built one ? would you not be better of getting another cheaper monitor which does not have a receiver built in ?


Excellent question. For the price and the quality, it sounded to me like the Black Pearl was already a pretty good value.

Is there a monitor that has as good of resolution as the BP, is at least as bright, and is $60-70 cheaper than the BP (i.e., the price of the uno)?
Howz about this screen and save £50 which you could spend on other things spare battery ect

Dont forget, if you get a screen without a built in battery, you'll also have to purchase a lipo and lipo charger to power it unless you already have one
 
Just got home and there is a note through my door saying my next door neighbour took in my package containing my new antenna set. Now I got to hope he comes back home himself before dark so that I can try them. :geek:

Good luck Shrimpy, hope you get a chance to fly with the new antennas tonight!
 
thongbong You are correct there just did not see the point in buying an Uno reciever as well as a Bp but i think if it was me then i would buy the BP first and see how it performs before buying an Uno .Ive seen the Bp in action an its seemed ok to look at and performed ok .

You've obviously got better weather than we've got down here..... it's just murk at the moment :(

I'll be happy with up / down / left / right / rotate for a while. LOL. Any way gotta wait for the Irish weather to die down... :(

I wish someone had an Immersion Duo5800 Diversity to try so we could see if it is indeed the BP that is the problem.
Not sure if you've seen this... http://youtu.be/04vQRTP61LE

It's footage of a Black Widow copter with a 25mW 5.8G ImmersionRC transmitter, ImmersionRC Duo5800 v3 diversity receiver, and CL/SPW and 4-turn helix antennas.

Signal seems pretty good at 800m, especially for only a 25mW transmitter!

A more expensive option, considering a screen needs to be added to the shopping list, but is this the way to go?

Somewhat independent of this thread, I bought three types of cloverleaf antennas and a Circular Wireless helical. Here is the test I did (this was updated to shorten it and to add comments - still kinda long):

The video is long but I wanted to show the full range for each combination. With three sets of antennas the number of combinations was huge so I just picked three. All three went BVR for me (not something I normally do). The helical was the hands down winner.

Here is the eBay link to the CW antenna:

U prob have mentioned this earlier in this thread.. But what Transmitter and receiver are you using?

I used a Diversity receiver (dual rx) and a TS 806 (actually labeled TS 832 and similar to the Boscam 600 mw). I have one on the Phantom and one on the F550. Lots of chatter about them but both mine work fine. For the helical test, I put a stick antenna in one rx port and the helical in the other. The helical has a narrower reception pattern so it has to be aimed - but is easy to use once the aircraft gets out a ways. The other antenna in the rx allows me to get the aircraft up and positioned without losing video - and allows me to dink around in the general area without issues.

Good work. I am not much of a distance flyer myself, but one thing I noticed is that you weren't that high up for the distance you covered. I don't know for sure but that could potentially impact the fresnel zone of the antennas especially if there are trees or other topographical features in between. I suppose that makes it a good real world test but I am curious if higher up, the signal would hold for longer.
 
$80+ bucks!! Yikes......nice antenna with some good specs.
But, same question-how is it, if you were at 100 meters in altitude?
We both have the same transmitter: TSC832. I'm using a generic Circular polarizer on the transmitter(RP-SMA), and dual Spironet(red cable), CP's on the Eagle Eye dual diversity receiver. As mentioned in an earlier post-good video out to 900 meters, at 100 meters up.
However, when I'm at lower altitudes-like what you were flying(using your CP antenna's), I see the exact same thing.
 
Higher would give better results but I wanted to keep it where I would likely use it. I could also mess with the antenna placement on the aircraft and a host of other variables. If you notice with the stick and clover leaf antennas, turning the aircraft around (thus shading part of the antenna which was on the rear) caused significant noise and distortion. This would be helped (a lot) if I had some altitude. However, using a stick antenna on the aircraft, the helical and making the same turn, I had almost zero noise show up at 550 meters. So even with shading the antenna, the helical was still able to get a good signal.

BTW - losing the signal on turning was a bit heart stopping - I'm not a BVR guy at all. Trusting it to do what I commanded took a leap of faith. I could have just turned the radio off but there was a principle. ;-} Finally hearing the rotors at about 280 meters and then spotting the airframe was quite satisfying.

My aim was to compare apples to apples for what I would be doing. I think the helical is the bee's knees. The CW version is expensive but I think IB Crazy has some at a good price, too. The CW version is extremely well made and is almost a work of art. It uses a laser cut lattice structure, comes with adapters for any SMA configuration, etc. It also has a complete set of specs with lobe definition and all that. It isn't a toy but it isn't terribly priced since it works so well - makes a marginal FPV setup into a very solid one.

what kind of receiver did you use? or is it a monitor receiver. anyway it's sucks man. you are wasting the true performance of the antennas you got. I can see the helical performed the best but my stock 3dbi whip perform 10x better with proper receiver like 5800uno.
