New Product
BluBeam antenna system from Video Aerial Systems

Today I officially launch the BluBeam antenna line of products available from Video Aerial Systems. The BluBeams are sold as a direct fit circularly polarized replacement for your stock whip antennas.

If you haven't tried circular polarization yet, you need to try it. Once you go circular, you will never go back to linear polarization. Circular polarization is a must for 5.8GHz.


Benefits:


Extended range
Exceptional video clarity
No more video drop outs
Reduction in multipath interference
No weakening of your signal in a turn
Better video clarity when flying behind trees and around objects

Long Range upgrade

Upgrade to a long range system by using a 7.5dbic helical on your RX. This will effectively double your range or more.
Upgrade to a very long range system by using a CP Dual Quad (coming soon) or a 9.5 dbic helical to your RX. This effectively triples your range or more.

Do not fly a long range BluBeam antenna system without a long range radio (LRS) or you are likely to fly out of your radio range!! Trust me, I've done this many times now...

Why no 910?

I'm sold out, that's why... I didn't anticipate 910 being this popular. It might be a while before they are back in stock as I need to get the parts which take a week or two. I can make two bottom feed units with a short extension. This is actually a better option than the BluBeams as it gives a little separation. Email or PM me if you are interested. I will give you the same price as the BluBeams.

The other issue with 900 MHz is the antennas are a bit large. They are 6" in diameter.

1280MHz is about half the size of a softball (4" in diameter and 2" tall)
2.4GHz is about the size of a golf ball.
5.8GHz is about as large as a big marble

Sadly, I am. OMM thinks it's an issue that the antenna is causing the video sync to saturate. I am investigating this. All I know is that it is a problem with the VRX. Every other RX unit works except early versions of the Airwave 5.8GHz RX module.

On the bright side, the Junk 1.2 GHz RX's do incredibly well with these. It puts them on par with the Lawmate's! The problem with the cheap digital ones is that their filtration was poor, but their sensitivity is good. With CP, the filtration issue is significantly reduced.

It's Volto's work, really. I just took the pictures and added some information.

I'm very impressed with your knowledge and hard work. Great antenna overview on your website answering just the questions FPVers need to know!

How about giving size measurements with each antenna on your website? It would help to figure out which one to get for a particular airplane / ground station.
Also, the helix antennas are named by dbi, but in other places suitable ones are referred to by number of turns.

I've got a 2.4GHz BluBeam set and the 9.5dbi helix in my cart. Some questions:

Are the the BluBeams RHCP like the helix?

What are the dimensions for the helix? Weight? Length?

Do you test the SWR for every antenna you build?

kendall

EDIT: Nevermind about the helix dimensions. I found your tutorial thread for them.

IBCrazy: What is the difference between the Blubeams and a cloverleaf antenna? Also, just as a suggestion, it may be worth having an option of a 90degree SMA connector instead of straight through, as a lot of people would have their VTX sitting flat on a wing etc, and with a 90deg connector you could have the antenna also sitting flat on the wing.

All antennas are RHCP unless specifically requested that they be otherwise. All of my antennas are compatible with each other.

2.4GHz helical is fairly small. Only about 6" long or so.

I test every antenna I build for SWR. This is the way I ensure quality. If it doesn't hit spec, I don't sell it. That simple.

The BluBeams are a direct fit replacement set to replace your rubber ducky antennas.

The skew-planar wheel and cloverleaf antennas have an extension cable on them and allow them to be moved away from the VTX and other objects.

Electrically, they are identical. The only difference is the construction.

The 90 degree connector will NOT be an option for BluBeams. That will put the TX case right in the path of the radiated pattern, thus harming the signal. I can make you a bottom feed SPW or CL with a 90 degree feed and a short 2" run of stiff coaxial cable if you like. That is how I am making the bottom feed antennas.

Thanks for the reply. I bought 2x Cloverleafs already from ReadymadeRC which will be put to use in the next couple of weeks when I get the Zephyr going. As for the 90 deg connector thing, thats fair enough, I didn't think of that. I'm happy with the cloverleaf design and the short wire going to it, will mount well on my wing. Thanks again for putting in all the time and effort to develop these amazing antennas!
