REFLECTOR: VOR/LOC/GS antenna

[Ron Brown]

Al,

I do have my instrument rating and I practice safe sex, I mean I practice approaches regularly, flying at least 6 approaches per 6 months and even when I'm not practicing, I'll tune in the ILS or LOC and monitor it during the final.  I have never seen a problem with Glideslope or LOC using the buried wing mounted LOC antennas.  By the way, they feed into a Garmin 430.  Also, if you've ever wondered why you have a hard time following LOC needles, watch your GPS.  You can have the path nailed, and the LOC will be "hunting" or scalloping due to interference with ground obstructions.  My best approaches are when I am monitoring the GPS bearing/track while also watching the needles.

  Al, 



  I ran across the same things as you.  I built my antenna's as per the old paper plans (com's in the winglets, VOR under the back seats, GS under the front seat, MB along the keel.) I contacted my avionics supplier after reading the install manual, and was told the following: I can use a high quality splitter on the VOR antenna (the one they supplied me cost $95!!!) and the SL30 will work just fine off of that. 

  I use the other half of the split signal for the GNS430, then run the seperate GS into the GNS430. The MB goes to the Audio panel. 



  That is a pretty simple solution once you choke down the high priced tiny splitter.

  Thanks Kurt and Ron;



  I shouldn't need the spendy splitter as the SL30 has that built in; and I want the GS/LOC info out from the SL30 to the EFIS.  The real issue is whether the NAV antenna in the wing gives a good enough GS signal, and Ron's experience would indicate OK,



  Thanks,



  Al
