How's your day today? (Dish Install) - Canadian TV, Computing and Home Theatre Forums

Kraven · 2012-03-15, 10:47 AM

As the snow melts every passing day I can't help but look at the spot where am going to install the 6 footer.

Wiring wise, am going to need to run rg-6 and actuator cables to the house. since all wiring here *must* be underground, would it be better to put the cables in some plastic tube for protection, like PVC piping or pool tubes? Or just bury the cables as is?

Also, is there a rule of thumb on how high the dish must be off the ground? Or the height depends on the reception? The only problem is I doubt I'll be getting 133w since its a low angle and the dish is pointing right onto the 2nd floor (unless the signal can penetrate the window, cross the den and out the other window..) and I can't put a pole higher than 6 feet off the ground.

Cheers, K

I would bury a pipe and make sure it is above ground on both ends at least a foot.

The real issue will be if you plant a garden or grow food.

If do not a plant garden then PVC should be fine.

You may want some holes in the piping so that water can drain out if needed. The last thing you need is water freezing in the middle of winter.

If you are gardening, then you can use copper, steel or amour cable shells for protection.

here's some info on installing a pole, etc.

http://www.geo-orbit.org/sizepgs/grn...ml#anchor72594

as for the height of the pole required, that depends on how far away you are from and the height of the obstruction your trying to clear.
Using a little trigonometry, you can calculate the required height to clear a house, or a tree, assuming you know how high they are, and can measure the distance to the obstruction, since you know the desired elevation angle (133 degrees sat => x amount of elevation in ur example).
Or just use the obstruction tool in dispointer.com, that's what it's for. To tell you how high an obstruction can be to clear it at X distance away.

I have seen two types of metallic tubing sold by the electrical distributors. One is called EMT.(Electrical metallic Tubing) the other is called SERVICE ENTRANCE MAST. The second one is much thicker than the EMT. Most of the stores like Home Depot only sells up to 2 1/2" of EMT and SEM, however I was able to find the 3" conduit at a site called NEDCO in Mississauga but only the EMT type.

Being the EMT much thinner than the Service Entrance mast, I am not sure if ti will be able to support the weight and specially the windloads occurring here in Southeastern Ontario.....Can someone shed some light please?

to support a big dish, aka cband dish you should use "schedule 40" pipe.
