Is there an external antenna for the OR 550?

Former Member over 15 years ago

Could anybody please tell me; is there an external antenna for the OR 550?

Thanks.

... and it there isn't an external antenna commercially available, would it be possible to fashion something?

The only connection on the Oregon is a USB port to use for power or to transfer data to a computer.

Are there any technical papers discussing the type of ceramic antenna used in the OR 550 versus the Colorado's quad helix antenna?

Thanks jrosedales.

It's rather surprising that there isn't more available on this subject.

FYI & FWIW
