Hi! Tony.
There's really not a lot to tell , other than follow Jim's advices, with
regards to angular displacement 's and lengths , and arrangement of toroids
etc. since you can't adjust any of it after layup! I found that it is best
to put them in the leading edge so the tail is already then at the spar.
I just stuck the copper tape down and glassed over them having fixed some
domestic plastic conduit ( down which was threaded the co-axial) down the
push rod void, making absolutely sure there is no contact from the tube,
because you will be a pretty sick guy if after all .........!!!!
I took extensive photo and measurement records to be sure the correct
antenna was ultimately
Identified for the correct purpose. Once it is all painted you have no
chance of reviewing your efforts !!!!
Hope this helps .
Regards
Bob Harrison. G-PTAG
