Default RX Antenna Routing

Where do you guys route your antenna wire on your big birds? Do you keep it inside the plane or route the tail end outside of the plane somewhere?

Thanks

I use a long piece of the blue nyrod ( inside usually yellow & outside blue ) and I use silicon to adhear it to the inside of the fuse and put the wire in it. If possible make an opening at the rear and slide a part of the tube outside (1/16 - 1/8" ) and then you can have the antenna sticking out the back.

Your end goal is optimal antenna polarization based on two omni's. This optimally in a perfect world, straight up or straight down would give you the greatest results (or at a slight angle, whichever is parallel to your TX antenna). Since that's not an option for us, straight down the fuse and out the back or out beneath the wing are your two best options.

In the FPV world, all most of us work on is antenna optimization for greater distances. It's been proven that out the wing @ 1/2 wave (minus velocity factor) provides the greatest distance. Since this is for a regular RC plane at short range, nearly any orientation works which is why most string it down and out the fuse. Just don't leave it coiled up next to the rx!

Also, please don't go tune your antenna length to 1/2 wave either as for general RC (non FPV) flying, you don't need the added sensitivity for long range. 1/2 wave's higher sensitivity increases the risk of picking up stray signals. Only reason we do this is for the greatest range in FPV as I mentioned.

Thanks for the replies everyone. So I guess that it is OK to keep the antenna inside the aircraft. Stretched out of course.

Just keep it away from metal inside the fuse, like pull pull cables, metal pushrods, etc. as those can cause interferance on a 72mgz. set. Range test the setup with engine off and running before flying, and you are good to go!
