How are you guys mounting your UHF tx case to your rc tx's?

I'm interested in seeing photos of how people have mounted their UHF tx cases to their rc controllers.

Just adding velcro to the back of my rc tx doesnt work because this would put pressure on my DX7's bind button also the direction of the antenna points more horizontally than vertically so in theory there would be a huge null area pointing forwards. I would like to come up with a way to mount the UHF case on the rail of the DX7 so that it points at least 70 degrees vertical. Anyone got any ideas of how I could mount my uhf case to the rail?

I was thinking of using two tail servo mounts but I dont exactly want to drill holes through the UHF tx case and I doubt I will find a heli that uses a tail servo mount small enough.

Hi..I used one of these and tyraped the Dragon Link on. It's nice adjustable set up. I bought mine from this ebayer but HobbyKing also sells these brackets.

That looks like a good solution!

rsands2801 even if I did do that, that still doesnt fix the issue of the null area due to improper mounting of the antenna.

If it cleared the case then I may be able to put a right angle adapter so yes or use a tx bracket instead. I have created a diagram to illustrate the null area problem.

Hugy do they have good enough grip? For example would I be able to adjust the angle of the tx case without it loosing grip?

Is anybody using a 90 degree BNC for the tx ant ?
I bought 2 of them because I thought the first one was broken or something
When I put the ant on the adapter ( 90 BNC connector ) the BNC is not able to hold the weight of the ant and it always rolls down with the ant pointing down.
I tried everything but I can't figure it out how to make it stay up
Does anybody have a solution for this ?
Thanks

I see now what you meant. i guess one advantage is it will allow me to tilt it up for extra range should i loose control but thats something to definately look into; fixing the way i mounted it

rsands2801 its not really about getting extra range its about mounting the antenna the way its designed to be mounted. The null area starts at the very tip of the antenna and increases the further the distance. This applys to pretty much any whip antenna.

If you havent done so already watch this video its very useful in understanding RF:
