Christian, Did you disable your FIFO in the serial port settings? In the /boot/device.hints file? This *really* helped my PPS stability on my little NTP box.
http://ntp.isc.org/bin/view/Support/KnownHardwareIssues For example, I have my serial port(s) set with the following flag: hint.sio.0.flags="0x12" ------------------------ As to answer your other questions: 1. Best thing to do would be to run winoncore and see what your SNR levels are. Then you can determine if the bottle/tape is causing any problems. You can usually find good all-weather GPS antenna's on eBay for like $30. 2. If your coordinates are completely incorrect it could lead to some weird issues. Again, I like to run Winoncore and let it do its self-survey then so you can monitor the data. 3. Being near other equipment shouldn't be an issue, but you never know. Again, running winoncore and monitoring the data for a while should let you know where the trouble lies, and also configure your receiver completely.
