Building an RV7 in the UK with a G3X system and thinking of using the z13/8 architecture with the SD8 backup alt and GAD27 to maintain voltage to the GDU etc during engine start. Is it normal or acceptable to keep the essential bus alternate feed on during flight in case of battery contactor failure? I'd rather not add a second battery.

If it can be inside how do you make a ground plane? Is it OK to be close to the COM antenna Thanks Mike --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus ________________________________ Message 3 _____________________________________ Time: 05:17:56 PM PST US Subject: Re: AeroElectric-List: Transponder antenna From: Robert Borger Mike, FWIW, I used the Archer transponder antenna for composite aircraft. It is a full wave antenna that doesn=99t require a ground plane. Works grea t. Having a warm body close to a comm antenna will distort the transmission pat tern. But it would be difficult to say how much. Better if it were some d istance away. I have my comm antenna in the tail.
