Got it figured out
OK, Bob Archer's instructions say to slide the antenna between the wing tip and the wing for a good grounding plane.
I didn't want to unrivet the plate nuts that held the wing tip on so I butted tt against the wing and ran a 12 ga. grounding wire from the antennae's to the wing.
The VOR and LOC were rock solid with good range on the VOR. As stated above the Glide Slope was erratic all the way down the chute.
I talked to Bob and he said that a single wire ground would probably not be a big enough grounding plane and in fact, with it slipped in between the wing tip and the wing that the wing itself would be a grounding plane as well as act like part of the antennae.
I removed the tip and drilled out the platenuts and slid the antennae under the aluminum strip in the tip, drilled it all out and reinstalled the platenuts and,,
Success..the glide slope doesn't even flicker.. Both the LOC and GS were rock solid. VOR reception was excellent at 3500 feet for a station 45 miles away. Didn't go any higher to check range but I'll bet it's better too.
When all else fails, RTFI!
