Welcome.
You have the first part correct, grounding the mast to the ground rod. It's your other intent I don't agree with, which is running a wire from your tuner to the ground rod. If memory serves me, grounding the system (tuner or no tuner) to the ground rod via wire may actually be dangerous, from what I read. You can do an Asylum search for this information.
A grounding block isn't at all superfluous. You are trying to protect your house, your system, and most importantly you from lightning strikes. The cable is a fine way for lightning to enter your house if you skip the grounding block. Don't cut corners, use the grounding block.
Below is a link to just one article I found. Google "grounding outdoor antennas" and that should give you plenty of results, including diagrams. You'll find far more results for TV antennas than you will if you search FM antennas, but it doesn't matter. For the purposes of safe grounding practices, they are one and the same.
Play it safe, and good luck!

Thanks very much for the advice. Sounds like a grounding block is important. I was planning on grounding the tuner directly because it advises to do so in the tuner manual (see attached pic). Perhaps I need to rethink that.
I'd never seen that suggested in a component's manual before.
The subject of system grounding can be complex. I did more reading on it this morning, attempting to find where I'd read about the dangers associated with improper grounding. Although I was unable to relocate what I was looking for, I did find many posts on the dangers of using a separate ground rod (meaning a second rod, in addition to your home electrical service rod).
I use a ground block for my outdoor antenna, in addition to a mast ground. My system is grounded using a power cord with a three prong plug, to make a ground back to the AC service panel. I've never had an issue with hum, except with phono, and that gets a separate ground wire, but it's attached to the component with the three prong plug (i.e. my preamp).
There's quite a bit of information out there regarding grounding. Search, and prepare to be busy reading for a while! The most important part is to verify the source, and don't follow the instructions of lunatics here on the Asylum. The advice might be great, but verify it! Don't trust your house or your life to a poster who may mean well, but has no clue.
Consult an electrician, if necessary. Be safe!

Thanks again for taking the time to offer advice. Looks like I have a little more reading to do. Cheers.
