7 tips for getting into a coaxial cable outside

There are many factors involved in burying coaxial cable. There are technical considerations, as well as code and security issues. 

Education is critical to avoid costly mistakes and to prevent you from experiencing signal loss.

1. Not all coaxial cables are directly buried

Someone bury directly some coaxial cables in the ground, and other cables are not.

 If you look at the cable and find the words “bury directly” on the cable, then you can bury it without conduit. 

Cables that are not specifically for burial will deteriorate quickly with exposure to soil and moisture.

2. Install duct

If your cable does not say “direct burial” on the cable, then you should not bury it without first feeding it through waterproof conduit.

 3/4 to 1 inch PVC pipe is an excellent conduit and can be pulled out of the ground using an elbow connector. 

Once the conduit is out of the ground, you will want to end the conduit in a downward or side position to prevent snow and rain from entering the pipe. 

You may need to add an elbow to achieve this. You can also use conduit to bury the cable directly as an added precaution.

3. Use waterproof coaxial connectors and sealant

 Make sure I designed all your connectors as waterproof. You can also apply coaxial connector sealant as an added precaution to request that your connections be waterproof. 

I specifically made these vendors for cables and electronics and should not use domestic vendors. Check with your local hardware or electronics store for this product.

4. Call before you dig

Call your local utility company to come to your home and mark all underground cables and wires. 

They will mark their property and use different colored landscape paint to mark the different wire. 

The paint will fade after a few rains and will also leave a streak. The best part is that it is free. However, you may have to wait 2-3 days, so plan.

5. Cable depth

You should enter your cable about 18 inches deep. 

You should also call your city building code office and see if there is a municipal code that specifies the depth of the buried cable. Some municipalities are 24 inches deep.

6. Use a trench shovel or trench hoe

 A manual trench tool should be suitable for a homeowner’s needs. Trenching machines are dangerous and should only be dangerous if you are experienced and have plenty of room to maneuver.

 Before starting your trench, you must first dig up your lawn along the trench line and set it aside for replacement after filling your trench.

 Cover the lawn with a damp newspaper or cloth to keep it healthy and moist.

7. Use warning tape

After backfilling your cable trench to approximately 6 inches, run a cable warning tape the length of the entire trench.

 It is printed with the words “Caution, bury cable TV line below.” Finish filling the trench at the top of the belt down to ground level.
