Yeah, you’re most likely correct Ken. We mount all our antennas internally, so
it that didn’t occur to me, but Bill might be constrained to mount his
externally with a metal airframe or surrounding structure.

Sounds like damage from the launcher,

Bill,
Any ideas why the antenna snapped off? Was it in the same area at the chute and
shock cords? Any photos to share?

Subject: [AR] Test Launch
Launched a 6” rocket at the MTA this weekend.
The rocket part worked fine: clean ignition, full 8 second burn. Bellybands
worked and separated as planned.
The payload had multiple failures: telemetry stopped at 119 feet and 425 ft/
sec when the antenna snapped off at the base. About the same time the payload
separated from the rocket. (The two may well be related.) Payload was
recovered and I will download the data for review when I get home.
The bellybands were pretty chewed up by the ride up the rail. The fins clearly
tore into the bottom band on ignition (bands were 0.020” 2024-T3). A redesign
with stronger bands appears a good idea.
