Usually remembers to get the pointy end up
So I thought it would be good to have a combination altimeter and GPS, and I got an eggfinder TRS as my first locator. My first rocket using it was single deploy, I built the avbay as an attachment to the nosecone, and the antenna (about 6") extended into the nosecone, out of the way, away from any metal, not using any valuable real estate. Great setup.
But I want to use it also for dual deploy, and I'm trying to figure out the configuration. Normally one would put the avbay into the middle of the rocket, with a drogue above and main below. Now, I can either make the bay 6" longer, and keep the antenna inside, or have the antenna extend through the bay endcap. Either way, it's 6" of wasted airframe. If it's inside the bay, I need to run igniter leads past the antenna for the ejection well on the endcap, which seems bad from an antenna standpoint - especially since one of those wires is probably grounded. If I put it outside the bay, it will be exposed to the ejection charge, so I need to protect it some way. And I'll still have ejection charge leads right at the base. Nothing here seems optimal.
Am I way overthinking this? Is there a good configuration for this setup? How do you guys do it?
Or, is it just not such a good idea to have a combo alt/GPS?
