Bury it all .. great!
Reason for pondering the 3 ought cable (for the leg-rod connections) is to provide a nice path to ground as I would think a strike would vaporize the #6, but if #6 is sufficient, I'll go with that.
Oddly, my calls to local electrical service suppliers are yielding results in line with HD. Sometimes HD is better, sometimes not. ie: they're better for galv. rods (by nearly $10 ea) but are lousy on wire prices. OTOH, I can only buy #10 ground wire by 1000' spool from the supplier and by the foot from HD. I'll be shopping around, picking up the components from here and there.
Internet service is via RG6 from the antenna to a standard cable modem with cat5 to my router.
Update: Just got word back from my ISP... they can run up to 300' of cable, so no worries! Woot!

just out of curiosity, do you know what type of wireless internet system you are on? mine is camvera; it doesn't work w/ a cable modem though. I have lmr400 coax coming from the antenna into a navini networks wirelss modem.

Found a good site for calculating how much wire can fit in a conduit: Designing Conduit Runs
They don't mention though (other sites do) that you should subtract 15% off the allowable fill for each 90deg elbow. If I stick to 2 elbows, then the 1.5" conduit (as suggested earlier) will be perfect for up to 7 runs. If I go with three elbows, then I have to bump up to 2" conduit or reduce the # of runs.
Then it struck me... I could use one of these:
to connect to my vertical riser at the tower and then horizontally into the enclosure at the tower base. This should give me access for pulling, reducing the # of elbows to 2 and reduce my conduit size from 2" to 1.5" (saves me enough to buy a weatherproof box). I think it looks neater too, esp. when compared to a 90deg elbow arching over the edge of the foundation.
Do you foresee any problems with this approach?

Do I know the type of wireless. Sorry, no I really have no idea, other than it's in the 5GHz range, employs a cable modem as my interface and uses pppoe on the network.

How many wire connections am I permitted per clamp?
Can I run the bonding wire from house to the tower and run around the ring using one contiguous piece of wire or should I cut the wire and separate the tower's ring wire from the ring-house wire (even though they'd still be clamped to the same rod)?
The supply house only had aluminum connectors (for attaching the copper to the galv tower legs). Are there are problems attaching aluminum to galv. metal?
How close should I drive a rod to a newly buried phone wire (that's been run to about 2yrd from the tower's foundation)? The phone line is going to be buried in the same trench as the conduit, which is the reason for routing it in this fashion.
Many thanks again!

i'm not a big fan of the aluminum connectors, but if that's all they had. . .
the rod is fine next to the phone line.
that pvc box you linked a pic of is called an LB. works fine.

those of DBSTalk.com, DIRECTV, DISH, The Signal Group, or any other company.

As the original poster is talking about a DIRECTV dish, I'm moving this back to DIRECTV installation.
huh? that's where its been since its inception.
