How to Install a Coax Cable Through a Wall: A Step-by-Step Guide

Installing a coax cable through a wall is a practical solution for connecting TVs and internet services in different rooms without unsightly wires running along baseboards and floors. Here’s a step-by-step guide to help you through the process.

## Shopping List and Tools Required

### Materials:
1. RG6 cable (available for $0.29/foot at Home Depot)
2. 3-way cable splitter ($6.97)
3. Universal Cable Jacket Stripper ($4.88)

### Tools:
1. Drill
2. Dry-wall saw (for cutting into drywall)
3. Electrical tape
4. Brown packaging paper and painter's tape (for prep work)

## Prep Work
Protect the working area by covering it with brown packaging paper and painter's tape. Plan the route for the cable, ensuring it will be convenient to access and connect to a cable box.

## Steps to Install Coax Cable

### Step 1: Drill a Hole in the Wall
Select a spot ideally between a door frame and the opposite wall, about a foot above the ground. Drill through the wall and ensure the bit sticks out on the outside for easy cable feeding.

### Step 2: Prepare the Cable
Use the existing cable and cut its end to expose the inner wire; this will make handling easier.

### Step 3: Feed the Cable
Feed the coax cable from inside the cable box and add it to a splitter. If necessary, use a 3-way splitter instead of replacing an existing connection.

### Step 4: Slide the Plastic Bushing
Attach the plastic bushing to the coax cable before feeding it back inside the wall.

### Step 5: Tape and Pull the Cable
Tape the coax cable to the drill bit using electrical tape and then pull the drill bit back to bring the cable through the wall.

### Step 6: Secure the Plastic Bushing
Press the plastic bushing into the outside wall. Enlarge the hole if necessary to fit the bushing properly.

### Step 7: Cut the Drywall and Attach the Bracket
Carefully cut the drywall and fasten a low voltage bracket in place to hold the cable secure inside the wall.

### Step 8: Strip and Prepare the Coax Cable
Strip the coax cable, folding the wire shielding against the outer insulation. Attach the connector to the coax cable, ensuring that about 1/8" of the center conductor protrudes from the connector.

### Step 9: Connect the Coax to the Wall Plate
Attach the prepared coax cable to the back of the wall plate, securing it firmly.

### Step 10: Secure the Wall Plate to the Bracket
Finally, fasten the wall plate to the installed bracket, ensuring a neat and professional looking installation.
