Hi Peter
Please let us have a copy of that updated drawing after the edits as

I think that a transponder antenna on that rib will work fine.
A bigger problem is a transponder that can only be connected to one antenna. There
is an article in the December 2019 issue of Kitplanes Magazine about the
proposed Canadian requirements and transponders.

Hi Terry;
You may already be aware of this but uAvionics is developing a Canadian
version of their wingtip mounted SkyBeacon.
More info can be found here
https://uavionix.com/testing-sbx/
It will be called SkyBeacon-X.
This is the option I'm waiting for.

Could a plastic airplane do with a single dipole antenna in the tail?
The Kitplane article (in 12-2019) does not say.

| Subject: | Speaking of LEDs |
The baggage compartment LED discussion reminded me...I'm putting in a
B&C backup alternator. The voltage regulator comes with an incandescent
low voltage light and they recommend keeping it. For aesthetic reason in
my new panel (part of the project), I would like to use an LED to match
the other indicators. I believe they want an incandescent because the VR
puts out a trickle current that will keep the LED slightly lit. Anyone
know if that's true and if there's a workaround? Or is there a more
serious functional reason it needs to stay incandescent?

A resistor is parallel with the LED will prevent the dim LED glow when it should
be off.
