It's not much to my mount really. I can try and take some close up pictures and give a full idea of what it's like.
As for the pipes, I think it's 1" pipe, but I really don't remember as it was over a year ago I built it.
It basically goes like this:
Flange (attached to the seat with the seat bolt) to a short piece of pipe. 90 degree pipe curve/turn/whatever and then a section of pipe up. I ended up getting another small piece of pipe and a piece to put them together to bring it up a little higher as they didn't have exactly the size I wanted. Your mileage will vary on that. Then to top it off I have another flange, and that screws into the 2x8 or 2x10 board that I cut to about the size of my laptop. To hold it to the board, I put 2 L brackets on the bottom side of the board.
The pipes spin (screw/unscrew) enough where I can push the laptop towards my passenger door or pull it closer to me and I can also spin it to change the angle I'm looking at it at. Is it a ram mount? Not hardly, but it is 10% of the cost! and it works really really well.
>*BTW-do you find it practical having a CB in your chase vehicle - has it been useful? Be specific please...
I hardly ever find the CB useful for anything but to know what a traffic jam is about. Traffic info is great. I hardly ever even put the K40 CB antenna on unless I plan on going a long distance and think that I might end up in a traffic backup. As far as the 2008 chase season, I never used it once other than when I was driving home one night and bored listening to the truckers.
>A lightbar , how useful is that - and what was the cost?
It isn't very useful, and I never have it on my car except for chasing. I paid $70 for it from Tractor Supply (It's $99 now). The only time I ever use it is if I am pulled off to the side of the road shooting video or stopped for whatever reason. In Michigan we have curvy/winding roads and hills and trees, and it can be useful here to have extra awareness on a road that isn't completely safe. I have only used the lightbar maybe a dozen times total.
>You have a Diamond NR-770 antenna; does it have enough gain when chasing in KS - any complaint?
It's a Diamond SG7500 and the thing performs very well. I have had the antenna for almost 4 years now and I don't have a single complaint. That antenna, coupled with my Kenwood TM-D710A has proved to be completely rock solid. I have been told I sound good on the air, and I always make it in very nicely from 'fringe' areas.
