I want to install a foil antenna for the VOR receiver. I'd like to
install the antenna ( foreswept " V " ) either on the underside of
the Canard wing or the main wing. My question is, after I solder
the foil to the two wires, how do I get the torroids and coax back to
the fuselage to run to the radios. I don't want to disrupt the shape
of the wing by running wires on the undersurface.
The junction of the coax and the two foil legs goes in the center of
the canard, where the underside of the canard is in the fuselage. The
foil is on bottom surface of the canard, in the wind, but it's so thin
it doesn't disrupt the shape of the wing.
THAT'S JUST THE PROBLEM. . . .THE JUNCTION BEING IN THE CENTER
OF THE WING. I DON'T WANT IT IN THE CENTER OF THE WING. TOO MUCH
METAL THERE FOR DISRUPTION. SO . . WITH THE CENTER OUTBOARD OF THE
FUSELAGE, . . HOW DO I GET THE COAX BACK TO THE FUSELAGE WITHOUT
DISRUPTING THE WING SHAPE ?
ANSWER : . . . I DON'T ! ! THOUGH I KNOW IT'S NOT THE BEST
WAY, . . IT SEEMS THIS IS WHAT THE EZ COMMUNITY HAS BEEN DOING FOR A
WHILE AND THEY ALL SEEM SATISFIED WITH IT, . .BUT AFTER READING AN
ARTICLE BY JIM WEIR, . .AND SEEING A SCHEMATIC THAT HE HAD SHOWING
SEVERAL ANTENNAS ON EACH EXTREME WING AREA, I WANTED TO DO IT THAT
WAY FOR BEST RESULTS. BUT IT SEEMS THIS IS NOT GOING TO BE WORTH THE
EXTRA EFFORT. SO . . . I PLAN TO USE THE VOR ANTENNA THAT IS ALREADY
GLASSED INTO MY CANARD AND I PLAN TO INSTALL A SECOND ONE FOR THE
GLIDE SLOPE , . .SINCE IT IS MUCH SHORTER ( ABOUT 7.5 " ). I PLAN TO
INSTAL IT RIGHT NEXT TO THE VOR ANTENNA SINCE I DON'T WANT TO USE A
SPLITTER. - - AGAIN, . .READING THE ARTICLE FROM JIM
WEIR, . .SHOWS THAT THERE IS AN AUTOMATIC 30% LOSS OF SIGNAL WHEN
USING A SPLITTER.
