can you use chimney mounts? like the kind for tv antennas? or is there any other good ways that dont necessarily require drilling into the house?
thanks

installing a base antenna

Sure you can use chimney mounts. Just so long as you can keep it secure in a high wind and away from power wires you should be OK.
Guy wires are used by most everybody to ensure that the top of the antenna stays stable. You can use either a 3-point guy wire system or a 4-point guy wire system. I use a 4-point system w/dacron rope. If you don't know what guy wires are, here's a quick link to look at.

It is better to use dacron rope guy wires, because they are non-resonating to transmitting radios, they are UV-ray resistant, and cost a little more than regular real guy wire. Hope that helps...

Look up 'Ham Radio Outlet' online. They sell the dacron rope for about $15 for 100ft. You will need the stuff they have, as the dacron rope is UV resistant. In other words, the sun won't cause it to fall apart after a couple of years of exposure to the sun light. Using clothes hanging wire from the hardware store will work and is cheaper; but it isn't the best way to do it...
Chimney mounts can be used for a lot of things, CB antennas included. There are some aspects of it that you ought to be aware of before going to a lot of trouble. Chimneys come in all kinds of sizes/shapes and are made from a number of different things. I think it would be a very good idea to sort of evaluate your chimney before you get too far along, you know?
Plain old tin stove pipe, clay tile, 14 tons of brick and concrete? See where I'm going with that? You don't have to be a structural engineer, some common sense ought'a work, in general. If it gets to the point where you think that structural engineer might be needed to make a decision, I think I'd give it a 'pass'.
Is that chimney in use? That can be a deciding factor sometimes. Lots of nasty goop comes out'a them things, will it affect your antenna? Or how bad will it affect your antenna? Putting a fiberglass antenna/feed line/whatever over the top of a lit fire just ain't too 'swooft', you know? Metal ones too for that matter. (That ain't how "turning up the heat" is commonly meant with radio stuff.)
Metal straps are the most common method of securing a mount to a chimney. The more distance between that top and bottom strap tends to make the whole mess sturdier. It can also be carried to extremes. More of that common sense thingy. And just how easy is that chimney to get to? Used to be a chimney/smokestack at a local power house. Would have loved to have an antenna on top of it. If you think I'd climb that @#$ thing to put one up there, you are stone crazy! Common sense, or chicken? I don't care, not me!
Guying an antenna isn't a bad idea. Sometimes it isn't too practical for a number of reasons. You have to decide that one.
Is that all you have to consider if you're going to put an antenna on a chimney? No, but it ought'a give you some indication if it can work in your particular circumstances.
Have fun.

i have a brick chimney and i dont think it would be to hard to set up. but i also dont want to rule out other options as well. basically im trying to find the most practical and and easy way of setting this thing up once it arrives in the mail.
and by the way, would this be the same doc from cbrt?
