receiver antenna placement

[Wayne Galligan]

I too have an outty.  My last ship had wire pull/pull everything in a c.f. fuse and I had nothing but glitching when the antenna was close to the fuse.  Had to run the antenna out to the wing tip.  Next fuse same type airplane I used a MK pushrod and no problems. Perhaps the wire pull cables and c.f. combination where suspect.   Are there any E.E.'s out there that could explain this phenomenon?

  I too run my antennas outside as my Aries is 100% carbon fiber.  I had in the past on a CF fuse experienced failsafe holds until I ran the antenna outside...Now the question is in my case and yours...at some time that fuse, that pushrod or those pull-pull cables are between you  and the antenna...why no failsafe here? 

  Also I have no trust in any Electrical Engineer, convinced that their expertise is nothing but smoke and mirrors designed to fool the mangement types, which is fairly easy to do. Why such an attitude? Because here at the Raytheon Antenna Department where I work , My EE's told me after running calculations that I would not have any interference problems- but I did. Regardless of all the missiles we make that have struck their intended targets, the EE's failed me in their most critical challenge....Can I run my RC antenna at 72 mHz inside my toy plane???? 

  I endure the scoffing at my "outty" antenna to enjoy a much stiffer plane.  I am of the opinion that an outty antenna is much more appealing than all those guys that have fuel tubing on the exterior of the plane! That is the true crime!  At least all my fuel tubing is hidden...

  I guess that I am not a real pattern pilot.  I have to run the antennas outside.  I have a Hydeout and a Focus.  Both use steel wire for rudder and elevator.  The Focus has a carbon rod for the elevator.  In both planes and certain conditions (example: slow roll when the antenna gets behind the steel cables) the radio has been going safe-fail for slit second.  The only cure after sending radio and receiver for tuning was to run the antenna outside.

  After having this experience, I am not confident to run antennas inside my planes.  I know that there is a very high percentage of pattern pilots that run the antenna inside.  Probably I am doing something wrong in the installation and I haven't been able to figure it out.
