Dick and others,
here's a generic path into handheld Next G / CDMA Wx radar.
Nokia 6255 top of the line CDMA (you may need to have the Web browser enabled by Telstra)
Next G phones:
Select the Web browser, this takes you to the Telstra Bigpond website.
Scroll down to News and Weather , press select.
Now scroll down to WEATHERNEWS and select that.
Select Weather Imagery, then scroll to Rain Radar.
You will get options by state and region, select the Radar site you want.
You can also animate the display, just as you can on the BoM site.
Also available is both static and animated satellite imagery, great for cyclones, and for getting an idea about what’s happening along the track.
CAUTION / WARNING
DO NOT USE INTERNET Wx info to try to pick a path through ,
Only use it to gain an appreciation of where to avoid.
hope that helps.
As for External antennas, most are trending away from that, even Nokia.
The capacitive/ inductive coupling by Nokia for Nokia phones isn't too bad,
just like your through the glass coupling,
but times two with the coupling, handset adaptor and through glass adaptor, so expect some losses.
