Cb Radio Antenna Do I Need The Cb Ham Radio Antenna On The Ground?

Do i need the cb ham radio antenna on the ground? - cb radio antenna

That is why I have this antenna for CB, ham radio is not on the floor, which is on the roof of my house. my house is not high, just a normal house normal. Am I obligated to the antenna is placed on the mast on the ground? and not the ceiling? and my antenna is on the pole and the roof of the house. Why antenna is called a basic disk? and why I have the antenna with a stick on the floor?

Function properly at a vertical base plate can, they have a tin, lead, or a radio network to be installed.
This sheet is called the plan "box.

If the roof of the house made of sheet metal form deck is made, it can be used as a word, right in the same way they are used in the installation of an antenna of the car.

It is not possible if you have to increase at the base of the antenna surface of the bridge, for example, a mast support tube on the ceiling.

If you get the antenna to a pole to the ground plane with radio replaced.
Radial son are connected at the base of the antenna and are about 1 / 4 wavelength long.
Tend to be down slightly for impedance matching, which they considered useful for certain applications, such as shroud is bent.

Even in a post has no impact on a so-called "loss of land. The Radio 4 May are all that is needed to operate the antenna means to be healthy. (But more is better)

NOW, if you install the antenna on the ground floor were losses on a much larger degree make use of radial tires.
AM-band stations Use 120 radially ..!!!!!

Normally, when not able to attract significant after 20 are up to 30 times or less radially.
The result with fewer radio that is required is the poor radiation efficiency.
4 radials just do not cut in this situation.

All this means that errors with a radial system. more energy is wasted, compared with a good radial system.

Another disadvantage of using a ground mounted antenna is the blockade of the signal by buildings and trees, etc.
Not only absorb that this decline in the strength of their input signals, but also energy, which means, once again, the overall efficiency below the antenna.

Vertical recessed floor can work well "appropriate only" when clearly "only" if used against a system suitable ground.

In these words, the fact is noted that most experiments, are rising, and far CBf requirements and often inefficient.

a base plate is a type of antenna, generally radially 1/4WAVE main 1/4WAVE.

You can use the antenna field, riding on the floor does get mount, but if one is limited in power to try (CB radio), all services, installed at the antenna as high as possible.

You must run a ground wire strap to the antenna, a ground rod. This will help the performance of the antenna to improve the ground reference.

Normally, I drive all my vertical antenna

I would put it on a pole with a ground wire when the storm .. Do I have when I was a year ago, was CB
do not blow that air to your radio
