comment How do I ground a TV antenna on my shed with the cable running underground to my house?
The voltage potential in the earth varies from one place to the another, even over a short distance. Bonding the two locations keeps them at the same electrical potential. All the voltage in your home is in reference to ground potential (0). If "0" is different throughout the electrical system, you could run into problems. Bonding the two electrodes allows "0" to be the same everywhere.

comment Can I use conduit to ground an antenna?
@MarcRochkind Before you proceed, you should insure that the conduit is "electrically continuous". You can determine this by testing the continuity (or resistance), from one end of the conduit to the other.

comment Connecting three wire dimmer switch (black, black, green) to four-wire cable (red, white, black, ground)
Without any additional information, I'm just guessing. Green connects to ground. white is capped off. Red connects to one black. Black connects to the other black. However, there's no way for me to say for sure, since you don't provide nearly enough information in your question. Do you own a voltage tester, or better yet a multimeter?

This answer might be helpful.

comment Coast 3-way — does this conform with Code?
I'd guess that before x/4 cable, you'd use two x/2 cables. The grounded (neutral) would be grouped with the ungrounded (hot), and the travellers would be in the other cable. Or you could run four wires through conduit.

What exactly do you need help with? Are you looking for a complete tutorial on how to do this, or are you stuck somewhere while implementing your solution?

This document lists the winter design temperature for some areas.

I'm only speculating, but I would say because the vent is full of moist air. So you don't want the moisture condensing and freezing on the pipe wall, as this could lead to a blockage.
