Rangevideo 2.4 downlink antenna orientation.

What's the best way to mount the antenna on 100 mw trans. It's just a little peice of ckt. board dangling on a wire. Should I keep it away from the metal skids or any Carbon Fiber?

I am thinking of using an SBEC to power it. Pros/cons?

Thanks Al. Someday I will again be Maine Aerial Photography Service. Thanks FAA holes.

Al-
I'm a noob - still crashing the sim in 10 seconds. That said, I am a microwave maven and have spent decades messing with RF in that range. The little etched circuit board is probable a little dipole. 1/4 wavelength each on the frequency of operation of your camera. Carbon fiber can mess with RF at that frequency. I'd locate it as "in the clear" as possible. Think of it like a flashlight bulb. You want your receive antenna to be able to see that light. 100mw of video at 2.4ghz or 900mhz can go a far way with a good receive antenna. If you want to make a better RX antenna, buy a ARRL Amateur Radio Antenna book. There are all kinds of fun antennas to make for these frequencies. I know I could send 100MW of video 10 miles with two good antennas.
Maybe I'll even be able to fly this Trex se some day!
Have fun.

YAVOR, The antenna looks like this. I think it only fuzzes when it goes edge-on to the receiver. Could I possibly rotate 1/2 of the antenna 90 degrees so it radiates differently?

Aramsdell-
I sent you an email...and for you others, as soon as I learn to fly this SE, I'll focus on Heli circular polarity antennas for 2.4gha and 1.2ghz. That is my zone. They will look super cool and work great too. The RX antennas will be larger and totally Russian Sci-Fi looking. Technical name? The Quadrifiler Helix.
It's all easy with the basic heli repair skills everyone has.

PS: a resonant TX antenna for 2.4ghz is 2.4" on each side. It's a "T" with the 10ga. wire elements at top and the feed coax is the center leg of the "T"...feeding each element.
