on a ply panel filling that recess with no form of ground plate. It has wor
ked perfectly with all tests OK. I note that in the current Rev F instructi
ons it does not say a ground plane is necessary, simply something like
=98for best results a ground plane is advisable.=99 It would not
be too difficult putting a ground plane in that space although it would not
be as wide as recommended but I see no reason to do so in the light of my
experience. Regards, David Joyce, GXSDJ
