Hey there, cool thanks. Where can I get the skew planar wheel for 5.8 though? I googled it, no sellers found.

Alex sells them:

http://videoaerialsystems.com/

So does Hugo

http://www.truerc.net/canada/

I make them upon request, but I currently have a too big backlog to help you out unless you like to wait.

I've seen that site http://videoaerialsystems.com/ but no option to add product to cart.

For http://www.truerc.net/canada/, they had the wind mill for 5.8. Is that the same as the skew planar wheel?

The windmill is not the same, but they work the same. In a sense they are interchangeable (Hugo forgive me)!

I've seen on the webpage that they are "on vacation", maybe you have to wait for some days more, but again, Hugo's antennas work equally well.

I will second the work of Hugo (www.truerc.net/canada). His work is exceptional which is why he and I design together. All of our products are compatible. The True Wire windmill/fan combination will do the same as my BluBeam set and both are compatible with eachother. You can get my BluBeams from here: http://www.readymaderc.com/store/ind...roducts_id=550 I know he's out of stock, but I am sending him a shipemnt this afternoon so he'll be back in stock in no time

Thanks for all the good information. So for a 5.8, I can get the cloverleaf for the TX and make the SKP for now, which is my first time, so I could mess it up. Should I just get the Bluebeams Alex mentioned?

Finished my first SPW, for 1180MHz. I've made it from 1mm steel wire.

Now I have to test it with the CL against stock antennas.

I'll keep it in a foam box (raw foam melt and cut to fit the antenna) to protect during transport. I think I'll keep it during running as well, the foam shouldn't affect it much would it.

Hi everybody, I’m new to the forum, I do practice FPV with a Multirotor MK, in France, I have been reading your post here on antennas from A to Z, and I have found it fascinating.
I did create, thanks to yours informations, my Pinwheel and Cloverleaf antennas and they do work unbelievable (only itch is: to be careful the way you land not to make a pancake out of it)…

My question: how important is the length of the feed point, should it change with frequency, does it change impedance, does it matter at all?

Second question: should the length of the lobes of the Cloverleaf (for a pair of matching antennas) be longer than those of the Pinwheel?? (I have found contradictory opinions on the matter)

Mike,

Yes, keep the feedpoint as short as possible and yes, the CL lobes should be about 2 - 3% longer than the lengt of the SPW.

Hi Guys, I'm very new to FPV. Sorry if this question was already asked 1000s of times and also answered that much I just cant find the answer.

I've got Fat Shark Predator RTF FPV Headset System 5.8GHz. It comes with 100mW transmitter and 3dBi antenna. If anybody use it, how far is the operation range of this system?

How much is Skew-planar wheel antenna capable to extend the range?

Thanks,
Ruben
