The first thing anyone needs before getting in this field is a psych evaluation.
If you fail, you are probably insane enough to do it.
lol
Other then basic hand tools that most people have. (1/2" and 7/16" wrenches, screwdrivers, pliers, wire cutters, etc)
I used the Acu22 when I did Wildblue because it was the only digital meter at the time that did WB and worked fine for Direct.
However, I would still recommend biting the bullet and buying the Birdog
Your ladders are more then sufficiently covered.
In fact, all I use is a 20 ft (little giant style Werner).
Goes from 5' to 9' a frame and up to 20' extension.
It also has a nice wide bottom so is very stable.
I get a little crap sometimes about how I need to get a 28 ft but the fact is, I have never walked a job because my ladder was too short unless it would have taken a 30-40' ladder.
Inclinometer is a must. Suunto as mentioned is the preferred one in the industry.
However, there are cheaper ones. But the few bucks saved may just not be worth it.
Cable toner or mapper (pretty cheap). You can get away without one if you want to plug receivers in and lick lines.
(don't do this with a power inserter unless you like pain lol)
Cordless drill (have spare battery)
Cordless impact (not a must but I wouldn't do the job without one and all those that I have convinced to get one has no idea how they got along for so long without it)
various dill bits wood/metal and concrete. Both long and short ones.
Flex bit
Post hole diggers and shovel
Fiber rods or fish tape (I prefer the fiver rods)
half a dozen hollow shaft aluminum arrows (yes I am serious).
Get them big enough to slide the cable in.
Cut the end off on a diagonal.
You can use them to run cables through hollow walls and find holes in floors without cutting away insulation
Various nut drivers both hand held and for the impact/drill
(Get hollow shaft for hand held ones)
There are tons of little tools and trick tools that different people use.
You will probably find yourself hitting the hardware store quit often in the beginning so set an extra couple hundred dollars aside for other tools and supplies.
