[OZAPRS] Antennas on bikes?

I mounted a D700 in my bike and fitted the GPS and antenna at the rear.
Had
to put some ferrites on the cable to the GPS to stop it resetting when the
D700 transmitted but it worked fine.

Had hoped the full tx would have kept me warm on cold nights but it did
not
seem too...

an etrex attached for APRS..  I'm wondering, if anyone has fitted up
antennas to their bike, where do you find the best place? I can't decide
whether it's best to do up mounts coming off the mirror mounts, mount them
off the side crash bars, or run a mounting bar to put the antennas either
side of the top box at the back..

Damien, On my 1000GTR, I'm planning to have a bar that mounts under the
top box...it will extend out over but not go out side the panniers.
Currently I just clamp a mirror mount to the pillion grab handles.
Be careful of where you run the coax, it was very close to the CDI unit.
I had an issue with the motor cutting out, when the D700 txed. I
suspected a faulty bit of coax. It replaced and rerouted, and all is
well.
I use a Diamond SG7900 dual band antenna..just remember to loctite all
the grub screws. Saves bits falling off. Is good for 160kph...tested at
Broadford Road Race Circuit last January.
Regards,
Ron
