Re: tower conduit
I would personally transition for the reason I listed earlier and that is for thermal expansion of the joints. It will make it easier to work with as well I think.
At least, this is how I would do it.... 
Nunya has more experience in conduit than I however.

What does LTNM stand for? Is that the liquid tight box terminator/connector? |

1 edit | Liquid Tight - Non Metallic
The rating is used on the box, connections, and flex / non flex conduit as well. But its definitely the rating i'd be looking for on this project. |

said by VariableARK  :What fittings would I use to seal the steel conduit? The screw down type certainly is not water tight. Compression couplers ARE raintight.
Thomas & Betts and Steel City are most widely available.
I would suggest that you use EMT if permanence is required.
Paint it -before- you put it up...far easier!

On this type installation, for flexible conduit (if needed) you would want to use LFMC (liquidtight flexible metallic conduit). You want the metallic innards for shielding / bonding / physical protection.

For that application you want steel not cast zinc compression connectors and depending on the length of the run you may need to allow a gap in the run or use an expansion coupler or two.

USA | I am putting my equipment box at the base of the tower. Should I bond the equipment on the top to the electrical ground or should I put a new grounding rod in? |

USA | Does that mean I should put a new ground in AND connect that ground to the common electrical system ground as well? |

| Does this sounds like an apt description of what needs to be done?
"Ground the antenna cables on the top to a common ground wire that runs down to the main box where the ethernet cables are ground and that ground is bonded to the electrical ground as well as it has its own ground rod." |
