Question about this antenna: (ibcrazy blue airscrew) http://www.readymaderc.com/store/ind...oducts_id=3611

In the product info it says its a straight connection but its really 45 degrees, is this a removable adapter so it becomes straight?

Thanks.

Hallo Alex

Why is it not possible, to only buy the vTX from the IBCrazy 5.8 GHz Bluebeam Ultra Antenna Set ?? My vTX is defective due to a crash on my quad-copter, and now i have to buy the whole kit again ?

So question mark. Do many people run these as rc transmitter antennas? Or is that not exactly a good idea?

The picture looks like there is a 90degree adapter. Best to contact readymade.

Some places sell them separate.

I've been using a Windmill CP similar to a Clover on my Tx for a couple years now. You don't get extended range doing that, in fact the range is slightly reduced but I've never gotten far enough away to notice and I fly gliders high and far.

Don't pay attention to the "loose half your range" blather, you don't.

Where the CP really shines is when used with a single linear antenna Rx. No matter what the orientation of the Rx the polarization is always the same. No major loss of signal because Tx and Rx are 90* out of whack.

What is the best way to fix this



My short bluebeam had survived a ton of crashes, I finally broke it bending it back last week, I moved this one form my hex to my quad and crashed it one time, I crash a lot we race them pretty aggressively, so now I am back on my Immersion RC antennas.

How can I replicate this flat wire design ?

New 5.8GHz antenna design
I have improved on the circular polarized 5.8GHz antennas by redesigning the elements. They were fighting each other causing a varying SWR throughout the 7 channel frequency range of the TX. Now there is no need to fine tune each one and set your TX to a specific frequency as there is very little change across all 7 channels.

Yeah, without making the element real ugly with tuning strips it's the easiest way to change the attenuation. A little time consuming though. They should all have a protective raydome, especially 2.4GHz and above. You barely touch those and they are out of tune.

Beat them flat with a small hammer. To be more precise you could use a broad, flat punch and a hammer.

Aparently that mod makes the (already fairly wide band) antenna even more wideband. I don't think this is realy a good idea. Upon recevieing it means that energy from other frequencies around the one you are using are easier picked up and upon transmitting it means that the antenna also tends to transmit on nearby frequencies. To make an analogy, one could replace car tires with ones using hard rubber (no air). This would prevent him from ever having a flat tire, but are these good tires for a car?

Then, remember, a good looking antenna does not have to be a good antenna. Of course a good looking antenna CAN be a good one too, but coating an antenna always carries the risk of makeing things worse. Its very difficult to coat an antenna and NOT negatively affect it's parameters. Of course, in the realm of DIY antennas with no propper measuring equipement the coating could also improve a previous inferior antenna. It's very very difficult though to build an optimal antenna with coating as you have to take the coating into account during the tuning process, hence tune the antenna "off" by the influence the coating is going ot have upfront. This requires a big amount of experimenting and gattering experiance for a particular antenna design.

Just my 2
