So she got there in the end. G-URMS is now officially certified for night &
IMC. There will be an article about it in the October LAA magazine.
Bring on the shorter nights!

Ron, I have a GA35 antenna for my G3X touch system with GPS20A and
GTX45R. The installation instructions at the time (Rev B) made no
mention of a ground plate and mine is installed at head level between
the doors on a ply panel filling that recess with no form of ground
plate. It has worked perfectly with all tests OK. I note that in the
current Rev F instructions it does not say a ground plane is necessary,
simply something like 'for best results a ground plane is advisable.'
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

Ron, As a P.S. I should say that my GA35 is in the over head space along
with an antenna for my back up GPS496 because I have my nav aerial at
the top of the tunnel just behind the D panel and my transponder antenna
attached to the bottom of the tail weight tower and of course the radio
antenna in the tail fin. That plan hoped to spread them out optimally
and it has worked very satisfactorily. David

Ditto everything that David said in regard to the GA35 and mounting between
doors.
Mine is an early version c 2002, outputs NMEA (so not just an antenna) and
only 9 channels.
However, I have found it to occasionally drop in steep turns; maybe it just
doesn't like turning.
