Introduction: Modern communication network and satellite channels are and directed through satellites, v-sat or dish antennas. When one program broadcast to every comer of the world, it is praised as the good fruit of modern technology. Techniques and sophisticated skills provide mankind ach facilities as the whole world is considered as a global village and the air Love the earth seems open for all now. It has formed a new culture-the open air culture and everyone is affected, influenced and sympathized by this media culture. This has taken the role of controlling the world-its economy, politics, society and culture. Now it is a matter of thought how much flourishment or nourishment can the culture do to promote humanity and civilization.

Dish antenna and important satellites: The antenna, which looks like a dish or plate and is used for receiving satellite programs, is called dish umenna. A lot of satellites are set in the space. Hongkong based Asia-sat is about 22,000 miles above the equator near Singapore. It is in 105" angle with the axis. Besides this, three Indonesian Palopa, three China sats, two Russian and European International Intelsat are conspicuous satellites. In Bangladesh, dah antenna was first launched in 1992. Now it is spread in every town and through cable operators, millions of people have become the viewers of satellite programs.

Positive effects: There is no meaning of being deprived of modern technologies. Satellite and dish are the technologies providing many good things to civilization and culture. Those are discussed below:

a. Expansion of attitude and outlook: Coming to the close contact with many different cultures and views through satellite programs, it becomes natural to get instinct of various ways and style of life. Thus human beings can compare their own with that of others and they can promote their capacity of adjustment. People can give and take everything of culture by presenting and watching programs on TV broadcast through satellites worldwide. On the global perspective it is necessary to survive in every respect and in this case the expanding attitudes help people to be proved fit in any situation.

b. Growing up consciousness: In the present competitive world, if one the winner, other will be the loser. So, getting the weapons of information and wisdom is badly needed to overcome this battle. For this satellite technology is the most suitable. Without being facilitated with the modern blessing of science, nobody but the isolated ones will be deprived and ruled by others. Because they will remain behind everybody else whoever gets the facility of satellite system.

c. Capturing international market: This is the world of advertisement The more something is presented attractively, the more will be the number of customers. From this commercial point of view, satellite technology is used in a large scale to promote marketing of every industry in this world. In fact, for business purpose, this lattest technology is being materialized In these media, marketing is being flourished and spread for better than other media. So, people relevant to trade and commerce also become dependent on satellites, that is, modern open air culture for upholding their products or arrangement. New approaches and strategies are invented to capture international market through satellite devices.

d. Publicity of own history and heritage: Every nation of the world tries to improve her position to a better extent as much as possible. For this purpose, one needs to expose all the things possible she has to present to the rest of the world. This is to attract and motivate others to venture tourism, invesment and establishments in favour of development. All these can be done by being the centre of attraction and facilities only through world wide open air telecasting by satellites. A nation can have rich history and sites for visiting to explore. This invitation is done by satellite broadcasting.

e. Discovery of new dimensions: Present world is prone to take the new and afterwards worships it. Satellites have opened the scope of horizons of continuous discoveries. It is the discovery of new dimensions in citse of education, entertainment, advertisement, presentation and becoming influential. The control of power in different sectors is gone to the ownets of the pioneers of open air culture. They are those who direct and guide satellite dependent channels. Human beings have become dynamic and important more and more for this open air impact.

Negative effects: 'All that glitters is not gold the proverb goes on with the croelty of open air arrangement. This new motive of the world is being iscussed for its poisonous claws by the thinkers. Being new and appealing, it welcomed but it has many bad sides. Those are as follow:

a. Destruction of native culture: Every nation has its origin which is based on native culture. But this root is being hit by the aggression of 'Dish-Culture' backed up by modern technologies. It has also happened to face the possibility of extinction in case of language, literature, songs, traditions etc. Thus specially the powerful and apparently charming western culture has replaced the pure and basic essence of a nation. This is obviosly destructive for the originality of a nation.

b. Demotion of morality: Honesty, nobility, chastity all these are the essential elements of human morality. These are affected by open air aggression and specially among the youth it has taken a horrific as the destroy of morality. As a result, corruption, violence, harassment-all these are increasing day by day. This hampers the stability of the country also.

c. New colonization: After the second world war, the colonial regime finished but it has come back with a new face in disguise of free culture which is telecast through open air or satellites. The owners or the premiers of this system are from developed and rich countries. They want to keep the poor or developing countries in control. So, they have adopted this policy of capturing the air, not they land. The want to rule and guide people of their former colonies from far distance by the remote control of satellite channels.

d.Cultural commerce and nudism: Culture is one kind of commercial object which can be sold or bought. This is possible today for open air culture. What was considered barbarism ago was nude culture. It demoralizes human sense and feelings. It becomes easier to guide or use nach demoralized ones. So, this is being spread and encouraged by open air owners for keeping people under control. The satellite side tries to conquer people being weak and lack of morality.

e. Spokesman for capitalism: In a high voice and spectacular tone, this Culture is rejoicing at capitalism and the deeds of this idea. Whatever the Jobs done by capitalism whether it is against humanity or not, satellite culture continues advocacy for the capitalists. Iraq attack' is a recent example of this, CNN, BBC these are no longer the channels having the so called neutral images. They are proved as the fighters for the westem and powerful capitalist people. They can say anything having their ill tendency of preaching capitalism.

Conclusion: We cannot but accept the reality of the scientific acceleration on the open air culture. We must utilize this modern concept for our purposes which will be beneficiary for us and our country. Powerful nations have made the poor countries helpless more by applying their new scheme open air culture. But we must modify this moden system through filteration. We must use our resources and fulfil our targets to overcome the evil intentions of satallite introducers. Govt. should form some regulations and apply some technical devices to stop the lower class telecasting in the open air culture.
