Hey Charley,
You're more than welcome to donate money (or time) if that's more up your alley. Also, if you want to donate UTP cat6, we'll take that as well. We use a bunch of ethernet cable both at the omni and for other installations, so we can always use more. If you're feeling really generous, we can really use shielded outdoor cat5 and cat6 for installing antennas. Don't worry - no matter what kind of ethernet cabling you feel like donating, we can almost certainly find a use for it :)
As for the questions you've outlined:
First thing: shielded cable
This isn't actually an ethernet run. It's dsl lines + phone lines running over cat copper wires. As such, it's my understanding that it's more sensitive to EMI disturbance. Additionally, it's much better to err on the safe side as we'll only want to string this once and the entire network communications infrastructure depends on the dsl signal that passes through this line. As for needing shielded mating jacks, we have plenty of grounded rj-45 connectors and with whatever other scenarios, it's pretty easy to ensure that they're grounded. We're not talking about our entire network infrastructure, we're just talking about this one cable run.
Second thing: hand termination
We're using an EZ RJ-45 crimper, which makes the process fairly straightforward. We have spools of other types of ethernet cables and have done runs throughout the building. Also - we'll be breaking out these pairs anyhow, so most of this is fairly non standard types of termination which are much easier than rj-45 disconnects.
Daniel, let us know if I missed anything here?
