    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! Read this topic online here: http://forums.matronics.com/viewtopic.php?p=498523#498523

    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.

    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.

    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.
