Montenaro ... thanks. You're right - it does add to survival value.
I found myself wondering about improvised antennas for devices that rely upon GPS signals and satellite transmisions. In general, there are tons of GPS satellites in the sky. However, it could also be that your own GPS receiver is fading out and losing its detection capability.
More importantly for me personally, I use one of the SPOT2 satellite devices as a personal locator and signaller for emergencies. It's fine for many areas of the world. But SPOT satellites do not have complete global coverage, so the signal reception is sketchy in some locations. That includes places I visit (e.g. Africa). So ways of boosting signals is a good idea!

None of these style devices are going to help you with your SPOT. All require hook-up to the device and SPOT doesn't allow for that. The SPOT 2 has a pretty good GPS receiving antenna. As for transmissions, the issue for SPOT reception is a combination of satellite coverage by Globalstar and their earth station locations. Boosting the signal, even if possible, is not going to have much effect on that in most situations except with perhaps with a heavy overhead canopy. But that has a lot more to do with power than antenna design.
