| Subject: | z13/8 ess bus feed |
Hi. 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.
Thanks

| Subject: | Transponder antenna |
In a composite aircraft does the transponder antenna have to be outside the
fuselage?
If it can be inside how do you make a ground plane?
Is it OK to be close to the COM antenna
Thanks
Mike

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.
