Extend exterior coaxial ground wire 4'



Lightning Protection for Exterior Mounting

Mount a grounding block (not supplied) as close as possible to the point where the downlead

enters the house.

The downlead wire from the antenna to the grounding block and the mast ground wire should be

secured to the house with stand-off insulators, spaced four to six feet apart.

For a "ground-up" antenna installation, you may not need to ground the mast if it extends four

or more feet into the earth.

Connecting the Antenna to Your TV

To connect the antenna to your TV, follow these steps:

1. Connect the coax downlead from the antenna to the ANT jack on the power injector.

2. If your TV has an F-connector, connect the short coaxial cable on the power injector to your TV's

VHF/UHF 75-ohm F-connector.

If your TV has screw terminals for the VHF/UHF connection, connect a 75-ohm to a...

Subject: Rear View Camera

Tip: I installed a rear view camera in the back of my 23 foot Rear Bath model a few years back. It was a wireless X10 camera that I found on sale and on a whim I decided to order it. It is powered by 12 volts and came with a wireless receiver. I decided to install it inside the coach by making a wooden bracket that attached to the top of the ledge above the rear window.

The receiver is attached to a factory installed coaxial cable (normally used for a VCR) in the rear of the storage box on the passenger side of the coach. The receiver normally sits inside the cabinet; however, it is show here hanging outside to show how it is hooked up. There is also a 12 volt power line installed next to the coaxial cable but I did not us it. Instead I ran a separate line back to a new...

If you use an exterior mounted television or radio antenna you should take steps to protect your TV and home from being damaged by lightning.

I do not claim to be an expert in this field, however I have gone to the trouble to find articles on the Internet by several people who are, and I have taken their advise with very good results. At the bottom of this page you will find links to several "expert" sites on this subject.

Protection for a TV antenna which is located on a roof should be at three points:

1) Ground Connections at the Antenna The antenna, mast and lead in wires (as well as control wires for the rotator or similar equipment) should have a ground routed via the shortest possible path, without sharp bends or kinks to a ground rod which is connected to the main earth ground for the home electrical system.

2) At The Entrance to the House The antenna coax should enter the house as near as possible to where the telephone or cable TV wires...

14 Gauge Dog Fence Wire vs. 16 Gauge Wire vs. 18 Gauge Wire vs. 20 Gauge Wire (thick vs. thin)

Most DIY Dog Fence Systems include a reel of 20 gauge wire. But, most professionally installed systems use a thicker 14 gauge wire. Why the difference?

Fewer Wire Breaks

The thicker the wire the more resilient and the less likely you are to get a wire break. For example, the thickest wire (14 gauge) is around 6 times stronger than the standard 20 gauge wire. This thicker wire also contains a thicker jacket, making it impervious to all but the strongest impacts.

When a dog fence is being professionally installed, we will usually use an industrial trencher, that is very tough on the wire. This makes using the thicker gauge of wire almost mandatory.

There are however disadvantages. Firstly, thicker wire is harder to work with. Thinner wire is is more flexible and easier to get into place. Second, the thicker wire is more expensive. The thicker wire uses...
