4. Remove metal base from plastic housing by removing the lock screw and sliding the base away from  
the plastic stalk. Mark hole locations on roof. Drill 5/8” hole for the coax cable. Pre-drill the 3  
mounting screws holes with a 1/8” bit. Route RG6 Coax from wall plate through hole. See Figures  
2, 3, & 4.

5. Apply approved caulking compound around all holes. Place base over holes and caulking. Secure  
base using the included 3 screws. Apply approved caulking compound to screw heads and fill ½”  
hole with caulking compound. See Figure 4  
6. Connect the 2 coax cables ensuring the fitting is snug (Do Not Over tighten). Reinstall the plastic  
housing onto the base. Reinstall the lock screw.  
7. Additional caulking compound may be applied to the outside seam of the base. Please note there is a  
moisture weep hole at the rear of the base. If proper sealing techniques are used (as described in  
Step 5) you should not need to add additional caulking around the base.  
NOTE: The Caulking compound used should be approved for the type of vehicle and environment.  
Check OEM recommendations for your vehicle. Material should be a non-hardening type such as  
Butyl caulking.

WALL PLATE INSTALLATION  
1. The wall plate/power supply assembly may be mounted in most electrical outlet/switch boxes. The  
plate can also be mounted without an electrical box. This mounting method requires a hole 2.75” x  
2.0”. Route 2 16AWG wires to this hole from the 12VDC source. Also route all coax cables to this  
hole. See Figure 5.  
2. Connect all coax cables to the appropriate wall plate pigtails. Each pigtail has a label for  
identification. Connect the cable from the roof antenna to the “ANTENNA IN”. Connect the “TV2  
OUT to TV input. “RADIO OUT” goes to the input of the AM/FM radio. “CABLE IN” connects to  
the Park Cable Input. See Figure 6. (Do Not Over tighten)

3. After connecting all coax cables, connect +12VDC wire to the + male spade terminal on the circuit  
board (marked with a red dot) using a ¼” Insulated Female Spade Terminal. Then connect the  
ground wire (marked with a black dot) using the same type terminal. See Figure 6.  
6. Install the wall plate using a two #6 Flat Head screws.  
7. Connect main TV to the TV1 output on the front of the wall plate.

OPERATION  
1. Select the desired source by moving the switch located on the front of the wall plate. Select either  
“AIR” or “CABLE”. AIR will activate the roof mounted antenna which will provide over-the-air  
TV and AM/FM reception. Selecting CABLE will enable you to receive signals from your external  
Cable Service provider and AM/FM reception. Selecting “OFF” will disable the system completely  
and is recommending when the vehicle is not in use or storage. Note the Red LED indicator will be  
On in the “AIR” & “CABLE” positions. See Figures 8 & 9.  
ANWP12V  
2. Next turn on all TV’s and access your on screen menu. (refer to your TV owner’s manual). If you  
selected “AIR” ensure that TV tuner is set to receive over-the-air ATSC/NTSC signals. Activate the  
TV’s auto programming sequence to scan / store available channels.

3. If you selected “CABLE”, then set your TV tuner to cable and activate the TV’s auto programming  
sequence to scan / store available channels.

4. The 7.5 Amp DC Receptacle is designed to power DC TV’s or other small amperage DC devices.  
The 7.5A fuse located on the front of the wall plate protects this receptacle and the power to the roof  
antenna. If this fuse blows then the antenna will not work. Do not connect high current devices.

5. Other wall plates do not have the DC receptacle and are fused at 1 Amp to protect the electronics.  
*Warning: Replace Fuse with the same Fuse type & current  
rating. Failure to do so may cause damage and void warranty.
