It s a long way from the rabbit ear designs you might think of when picturing indoor antennas and much cooler looking than the metal contraptions often found outdoors.
Antenna attic ground plane square.
I want to cut the cord and put a antenna in my attic.
I have no idea how to ground it though.
Note that you do not have to run the ground wire from the antenna you can ground the boom to the coax using a grounding block and at the other end run a ground block and grounding wire to the main ground.
It is found that for a monopole antenna like a quarter wavelength vertical the ground acts as a plane to reflect the radio waves so that an image of the top half of the antenna is seen in the earth.
As the name indicates the antenna ground plane acts as a simulated ground.
The only concern with attic mounted antennas is the space available to you for mounting.
This works electrically it may not be legal in the us.
It is possible to simulate this function by replacing the real earth.
The ge 33692 attic mount hd antenna is a notable example of an antenna specially designed for placement in the attic.
Most of them can tune to 10 meter as well.
The ge 20431 futura outdoor indoor attic tv antenna is one of the best looking options on the market.
I have read many mixed opinions on grounding in the attic so i have decided to ground just to be safe side.
We are also fabricating a ground plane or counterpoise by using the correct length of copper wires hooked to the mount.
My house ground rod is not to far from where the antenna will go but the copper will have to go out and down one side of my house.
If you are building i leave that up to you cb antennas are available fairly cheap brand new and used.
The kb9vbr 2 meter j pole antenna is 69 inches tall overall.
Run a ground wire from it common ground rod where the electricity enters your house.
You will need a peak in your attic that is tall enough for the antenna to fit.
