I've been thinking about building a glide slope  antenna and was wondering if anyone had done this.  If so, any ideas would  be great.  Pros and cons are welcome.  Thanks in advance.

According to my calculations, a quarter wave glideslope antenna should be 21.9cm long.  I believe it is horizontally polarized.  A temporary antenna can be a length of copper tape stuck onto the windscreen and soldered to the coax center conductor.  Attach the coax shield to the adjacent windscreen metal frame.

   Do you have a VOR antenna installed?



   If so, consider using a coupler to tie the GS

   receiver to the VOR antenna.

   While a VOR antenna is not the IDEAL 

   GS antenna, the signal from a LOC/GS system

   is huge . . . the ship's ILS system can

   tolerate losses introduced by this coupler.

Thanks Bob.  I hadn't thought about that yet  but that sure will save a lot of time and effort.
