Do yourself a favor and don't try to use a regular drill. It's worth the trouble to go to a tool rental place and get a hammer drill for a few hours. It'll turn a 45-minute sweat-and-curse-producing ordeal into a 30 second piece of cake. I'm a big believer in getting the right tools for the job.
Hammer drills come in different sizes. For brick, you probably want to stay away from the big monsters that'll put 1.75" holes in concrete, as brick can be kinda soft. Smaller ones are no bigger than regular drills.
You have a right to install OTA and dish antennas on property under your control.
A regular drill and masonry bits (probably a half-inch bit) will work but as one poster points out will take time in the BRICK. But if you drill into the mortar joint it won't take long at all (and that can be easily patched later if you remove the stuff). Just move your anchor plate around to line up with mortar joints, or drill some other holes in the plate to match the mortar joints.
You also need some masonry anchors to fit the holes (or a drill bit to fit the anchors and screws). These expand when you put the screw in to hold everything tight, and when you remove the screw the anchors can be removed too as they collapse down again. These are about an inch long (depending on size) so you only need to drill into the brick/mortar joint that deep so they fit.
If you are really concerned about how well they will hold you can use longer lag screws without masonry anchors -- drill all the way through the brick thickness with your masonry bit, and then screw the lag screws into the sheathing underneath. These lag screws will probably need to be about 4 inches long (or more) as the brick is maybe 3 inches thick, there is a bit of a gap, then into the (plywood usually) sheathing behind the brick. Those will need about a 1/4 to 3/8 inch hole/masonry bit.
If the anchors are a bit loose when you put them in, mix up some epoxy and goop it in the hole to hold everything tightly. It will be a bit harder to get the anchor out if you want to do that later, but a little chisel will do that job.
You might also have to drill all the way through the brick/mortar and sheathing to run the cable in somewhere around your TV unless you can get it through a window or some other opening.
Been there, done that...took me maybe 30 minutes with a regular drill and masonry bit. Note also that you can pound the little cable clamp nails into mortar if you tap carefully and don't bend the nail -- looks very professional.
You will need to visit your local hardware store. Depending on the size of your bolt/screw (take one with you) you will need a masonry bit (aluminum colored and doesn't look very sharp) Just ask them and they will show you.
Additionally I don't have much experience with fastening items to brick, but ask someone who works in the hardware dept and they should be able to point you in the right direction. Take the hardware with you that you intend to mount to the brick.
I put up a similar mount using a regular drill (18V cordless) and drilling into the mortor not the brick. Also, if you are concerned check your local equipment rental places, usually you can rent one pretty cheap for a few hours so you don't damage your standard drill.
You should be fine with a regular drill and a bit which is not worn out. It's slow going but not that slow. Depending on the condition of the brick, you will need to decide how deep to drill your holes. With the use of expansion type plugs/bolt you shouldn't have to drill more than 1 inch. This will depend however on the weight/mass of your antenna and mast assembly.
Again, the hardware guys should be able to advise best.
You will need as stated above a rotary hammer drill. Buy 2 1/2 long by 1/4 inch expansion anchors. They come with washers and nuts. Put the washer and nut on the end of the anchor, this to avoid damaging the threads while you hammer in the anchor. Use a 7/16 inch socket to tighten anchor.The anchor will expand and anchor itself while you tighten it down. Repeat as neccessary http://www.avsforum.com/ubb/smile.gif
