Hi Bob,



I hate to be a nag, but our DAR inspection is tomorrow and I'll be starting 

ground/flight tests after that.   How's the antenna coming?



Thanks!

-James

Jim, finished one of these and was disappointed in performance.

 The thing is so tiny that it's hard to troubleshoot,

 assembled a second just in case.



 I think the best plan-b for now is to install

 a quasi-sleeve dipole . . . except that the 'sleeve'

 is just a piece of wire. I forget how long you said

 your antenna conduit was, hopefully considerably

 more than 26".



 Make the antenna from wire stiff enough to push

 into the tube on the end of the coax. Wouldn't

 put a connector in the counterpoise. Just thread

 it to the ship's interior on installation and tape

 it sort out of the way.

 I've got a couple other antenna projects on the bench

 but some buys waving credit cards have purchased some

 keyboard/hammer-n-tongs time . . . and I've got a couple

 of pots boiling for B&C.  I'd like to pursue the

 active antenna experiment. It would be useful to field

 test the idea in close proximity to transponder and

 vhf/comm transmitters!



 In the mean time, let's get your airplane flying.

Thanks for the reply and progress report.  I was really hoping for a  successful test, but yes...the immediate goal is getting the bird through Phase  I.

  

 The conduit is sufficient to install what you have described below.   Maybe that will be enough?..I guess we’re going to find out one way or  another.

  

 I’ll report back with what we find in the coming weeks.

  

 Thanks again.
