[high antenna gain performance] As for our rod antenna, the body is more compact than other brands, but antenna gain performance doubles 5 in comparison with 12DBI and other brands. In addition, not rod antenna, the film antenna for the vehicle installation generally has only 3DBI. As I have gain performance at the same level as a home high efficiency antenna if it is our rod antenna, I realize the reception environment that there is not of the stress. [clear an image] Because the reception strength of the antenna is higher than the product of other companies markedly, from high gain performance, I can output a clearer image. As the quality of the image formation of the screen in particular is important to the person who wants to enjoy a movie, it is pleased with the which you used very much. ※A difference may come out to reception strength at distance to system music in the topography and the rainy season. [there is much number of the reception channels] Our rod antenna can receive all channels of the TV. I completely cope with terrestrial digital broadcast and have the area of the range which can receive the frequency of all channels. The correspondence spectrum is 470-710MHz (13ch - 62ch). [usable immediately just to come in] As a terminal of our rod antenna is "an F type male terminal", use it just to insert it in car navigation system TV, a TV monitor, and the choice and the preparations for connector that it is difficult are not necessary. To conventional other brands, I purchased a connector for, in that case, a lot of things of the scalpel-shaped terminal to insert it separately, and it was necessary to brace it. As there is not such an agony, anyone can use our rod antenna immediately in peace. In addition, connection is easily possible if I use 3.5 〓 terminal conversion cable for various devices such as a tablet and the smartphone. In this case as you need a conversion cable, please check the terminal of the product at hand. [I carry it with a compact easily] Our rod antenna is the size that it is easy to carry with a compact. When was not an extension type in the case of conventional products rod antenna, the length was obstructive, and, as for attaching it, there were many things which there was not of the use to a car, but 11 〓 (as for the other brands 19 〓). only with our antenna as for the length You load it onto a car and use it, and it is possible to take it to go, and to use it for a house easily at necessary time and can carry it quickly in a house and can use it at a place to like. Though the reception situation is good in the living, I am not reflected neatly in the room on the second floor…I can enjoy TV without the stress in such a case if you can use our rod antenna.
