Hi Gilles,
aircraftspruce most of the time has documentation to what they sell:
http://www.aircraftspruce.com/catalog/pdf/G207instruct.pdf
I know not before the weekend bust I was abstinent on emails :)
Cheers Werner

Hi Werner,
Thanks for responding.
Unfortunately the Series 4 stick grip document remains unpublished to date.
Thanks to the great guys on the 'List, I got the documentation within
hours, and was able to deliver the schematics on time !
Thank you everyone !

The gear legs will affect the radio transmissions and reception. Exactly how much
can only be determined by testing. You can install the antenna then go fly
and try it out. You might be satisfied with it. Or maybe not. An option is
to mount the com antenna on top of the airplane. Theoretically the airplane
will block the signal from reaching the ground. But in practice, top mounted
antennas work fine. The same might be true for an antenna mounted between the
gear legs.

Always bear in mind that the fuses are sized to protect the wire and what is
connected at the other end (in this case your radio) has no influence on the
fuse size used.
As long as the wires are adequate for the 10 Amps then 10 Amp fuses are fine and
certainly if the existing wiring will supply the new device's requirements then
they may be reused/re-purposed.

I have a bent whip on my RV4 between the gear legs just aft of the firewall.
I haven't had any problem communicating once airborne, but on the ground at
certain airports I have a heck of a time getting hold of the tower.
I'm building a full IFR RV-7A, and plan to put one antennae on the bottom of
the plane, and the secondary radio antennae on the top in order to switch to
whichever radio works best per the situation...

I had the same problem on my RV-10. I moved one antenna to the top, problem

Hi Bob
You are right that the fuse is there to protect the wire, but the size
(in A) of the fuse is a function of the current which is drawn by what
is connected at the other end of the wire, isn=99t it?
Otherwise you could put a 1A fuse to protect a #24 wire with a pitot
heater at the end, and you would never see that heater working when you
wanted it.
With due respect
Carlos

Hello,
most avionics do have PWR and GND on two pins. My SL30 had even one used
for the NAV part (3A fused) and one for the COM part (5A fused).
I have to replace it with a new 8.33, but just going for a COM right
now, that one has as well 2 pins each tied together, PWR onto a 10A fuse
(8W COM).
Is there any disadvantage, if I use the existing cabling with the 2x
GND/PWR on extra fuses? Should I use 2x10A fuses (for a 8W com I found
the 10A a bit high).
Thanks for your advice
Cheers

Not Bob,
However, the wire has to be sized at a minimum to carry the anticipated
load, so you would not have the situation you describe.
On the other hand, it is common that relatively small loads, say 1 amp
are carried on 18-22 gauge wire, and would be fused for what the wire
can carry, usually more than what the load is. Another common occurrence
is that wires for lighting on a plane were sized for an incandescent
load, but the lamps have all been replaced with LEDs that draw 1/5th the
amount. The circuit breakers would not change, because the wiring did
not change.
