Hi Andy,
With respect my experience is "KEEP THE TM1000 Antenna WELL CLEAR of your receivers.
I went to a jet meet with my shiny new TM1000 fitted and didn't notice the antenna had folded back and was resting near one of the receivers.
Telemtery went mental 10 seconds into flight and I was lucky to land immediately and get away with it. Checked soon as I had landed and it had several holds. (Aircraft has flown for 4 years with no issue).
Subsequent range checks were rubbish - frame losses and holds - until I spotted what had happened. I moved the TM1000 antenna back to where it should have been and anchored it properly - haven't had an issue since.
Right or wrong this was my experience
Dave
