cheap monitor W/O tuner for adj antenna hooked to CECB (where to buy?)

Well, you can look around at the $19 to $29 5" B+W TVs that are sometimes as low as $9.99. Or look in the classifieds for used small portables.

I think finding a monitor with composite in working condition would be harder.

many portable DVD players have AV in.
Also portable GPS mapping units do too, then you have a second use for your purchase.

But remember. Keep the CECB right where it is going to be and run a long wire from the RF out. Don't relocate the box, relocate the TV feed.

I have a Casio handheld TV that has A/V in. The issue is rather how to get the power for the CECB.

I would suggest a dump way - just listen to the sound of the TV. With digital, if the sound is continuous, it is good signal. Many cordless phone can do intercomm. Or you can just make the speaker really loud...

Oh yeah, theyre all over the place. Just look in department stores like K-mart and in my area Boscovs, Value City etc in the radio section of the store. Walmart used to carry them, but I havent seen any there lately. And they seem be at a lot of yard sales and flea markets. Most also have an AM/FM radio built in and run on 10 "C" or "D" batteries.

Hit a garage sale and buy a 13 inch TV for $10-$15. Leave it in the attic for the next time to want to check.

Yeah an old 12-13 inch B/W set should also work fine - if you can find any

Or get a free one: http://www.freecycle.org/

(You can post a "WANT")

Or more likely at garage sales for a few bucks.

I'm sure people won't be just tossing out perfectly good CRT's, or less likely, plasmas, especially larger ones that they may have paid hundreds, maybe over thousands of dollars for just a few short years ago.

You may see a few really old little ones in the trash, but you'll probably be lucky to see anything that good. Plus, I can guarantee you you're gonna have to work pretty hard and get up real early to beat the illegals. In my area, if someone who is dependent on a wheelchair so much as leaves it unattended in their front yard or driveway for 5 minutes, you can be sure one of them will have taken it by the time they get back. That's actually happened on more than a couple occasions.

Searched but could not find a post describing this. As I had dragged a small TV and CECB up to my roof in adjusting the antenna, why would it be better to have the CECB in its final location when doing the antenna adjustment?

Adjustments and variables and phase of the moon can all affect things. So often if you can do adjustments with your final setup it can be best. For example adding another run of coax or a splitter could affect your final result and you would want to include that in how you setup.

There is also the point of view that you should start simple and build from that. It takes way more time but often better results especially if you have less then optimal situation (old equipment mixture, not a strong signal, and so on). If you throw marginal stuff together you never know if it is a bad coax connector or a weak tv signal that gives you no video.

I will sometimes start with a final configuration and if that doesn't work then start to build it up simple (or at some intermediate point). All depends on your troubleshooting skills, levels of flusterabilty as to where you want to start.

For aiming antenna doing so from the roof would be fine, easiest and safest just to stay there. If you see a signal there then you are good for aiming, the rest is downhill coax, switches and splitters. Just test the end of your coax at the grounding block before taking down the ladder and making the coax connector at the antenna weather tight, if you see a signal there then your antenna aim is good.
