[TowerTalk] Rotor Cabling Query

I would like to hear from those in regards to ideas for the following. I 
know there are those who have long runs of control cabling for rotation, 
switching, etc. so I seek your ideas and advice.

I have a need for a temporary set up of a run that is 300 feet from the 
operating position shack/controller to the top of the tower controlling 
a Ham 4 rotator. The final set up with be a run of 700 feet from tower 
to the operating position shack/controller

Would it be best to provide a disconnect near the connection point at 
the top of the tower with a short pigtail to the Ham 4, as well as a 
disconnect/splice point at the bottom of the tower, and a final run to 
the shack/controller?

Based on previous discussions/ideas tossed around here within the last 
2-3 weeks I would most likely take some ideas from the group in regards 
to utlizing trailer type connects/disconnects and also splices within 
the entire run.

A primary point/concern of my post is the length of the run on the 
temporary 300 ft and to the final goal of 700 ft. What size of the 
conductors/wire/cable to utilize for the effort. Some part being heavy 
duty 8 conductor rotor cabling in conjuction with splices and/or runs of 
UF solid wire cabling from 14 gauge to 10 gauge such as 14/3, etc. or 
other such ideas on conductor size. A reasonable cost/maintenance 
perspective would be ideal keeping in mind going from the 300 ft to the 
700 ft in the future and ease of said transistion. None of this will be 
buried, I have that part taken care of.

*(tower/rotor)*****short pigtail/run-->>>---*****(pigtail/connect 
splice)*****run to bottom of tower -->>>-->>>-----*** **(bottom of 
tower/connect splice) *****--->>>---->>>---*-****temp

ft expanding to 700 ft>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>>> (later 
to be the permanent run)>>>>>>>>>>>>>>*** **to connect/splice back to 8 
conductor rotor cable ham 4 controller in shack.****

Besides possibly utilizing trailer type connects/disconnects I was also 
considering utilizing 8-10 conductor terminal blocks for 
splices/junctions etc. and I could possibly place those in weather 
resistant boxes at those points where required....What is the thought on 
that approach?**

Thank you for all the input/ideas and73! Ed K5OF in NC
