[OZAPRS] OT: what to use for Antenna Tip?

[Damien Gardner Jnr]

Hi Rob,

Thanks, I'll have a chat to the guys at Metaland tomorrow, and see if I can source it here.. if not i may take you up on your offer :)

The tip is 152mm long, just over 3mm diameter, so likely 1/8" :)

Silly question - is stainless always shiny??  Perhaps the stock tips are stainless, but I've only ever seen shiny silver stainless in kitchenware, so was assuming not, as they're not shiny ;)

Regards,

Damien
