They're located about 2 miles away from me, next time I stop by I'll laugh at them for you...

lets not forget a pair within the cat5 jacket will be longer due to the added twist

"The higher the category number, the more twists and therefore more copper wire per running foot of cable."

I don't think anyone has forgotten yet. I only said it three days ago.

If a 6 pair BSW is too cost prohibitive for you, you can also get a 3 pair BSW that may be a little cheaper for you, if you only plan on using one circuit.

More than once I've used single pair areal drop for direct bury, when interference from other services wasn't an issue. It's some tough stuff!

Eh, I wouldn't be burying aerial drop wire unless I was completely desperate. For one, it isn't filled. It also uses a different compound in the Polyethylene insulation for the conductors than that is used for buried wire. It can tolerate occasional moisture, but not long-term exposure, as in buried and full of water.

Yes, BSW is available all the way down to two pairs, in fact I have two 5,000 foot reels of the stuff if anyone is interested!

I would hesitate to use fewer that 6 pairs, just for maintenance reasons. It's a lot easier to swap a pair than to locate, dig up, repair, and re-bury a fault.

When used with (series) voice and gate release features, you need three pairs to start with. That means you have 0% spares for future work.

The power and relay for the gate motor will be local and running on a seperate cable than the buried cable to the house, but I agree, the more pairs the better, especially in this situation of 1000's of feet of buried conduit.

As was mentioned use BSW 6 pair. Remember to follow the proper grounding and bonding procedures for the 6 pair.

So we went up to the ranch for phase 1. Installing cameras at the main house. The fiber guy was running cable between points. This is so far out in the country that the local LEC guy has agreed to let us use his cable from the road to the house for the gate. The trench for the gate passes right by a telco "Pedastool". He's going to run a cable to that pedastool and the telco guy will give us two pairs to the MPOE at the main house.

As a backup their is fiber between the main house and a gate junction point, then there's a cable from the gate to that junction. We can install a fiber to analog converter for the gate if needed, although I hate relying on adaptors.

The plan was to run a cat3 from the house to gate but the owner ran only a 1" conduit that the fiber is in and we can't get an additional cable in.

Here's a pic of the camera server in his wine cellar.
