Grounding clamp - pipe can be used to make a solid connection to an antenna mast. Some people just add a washer under one of the bolts that hold the mast mounting bracket and then use the bolt to clamp the ground wire to the mast and bracket assembly. Be sure that the ground wire makes metal to metal contact (not wire to paint).

Split-bolt is used to connect ground wire to existing heavy gauge wire such as the cable from your service panel to the ground rod.

Ground rod clamp is useful if you are going to connect ground wire directly to a ground rod.

Coax ground block is a simple way to make a grounding connection to the coax shield.
As you see, most or all of these parts are normal stock items at the home improvement stores. I didn't spend much time looking for the single coax block on the Home Depot web site, but I found dual blocks (for satellite and multiple antenna installs). I'm fairly certain they carry both styles.
The #10 wire is available by the foot, bare or with insulation. Home Depot also stocks Scotch brand #2228 Moisture Sealing Electrical tape, useful for sealing coax connectors from the elements.
