"My TV reception is so clear; you’d think I had a
50-foot antenna (天线) on my roof!"
I’m amazed at the way technology has improved television. From the silent film centuries ago to three-dimensional videos, technology also changed the role TV sets have played in people’s daily life. Developments in electronic circuits have resulted in TV sets that have sharper pictures, brilliant colors and clearer sound. From the smallest portables to wide-screen home theater systems, televisions continue to work better and better as visual innovations are introduced. In addition, various TV programs, from current news to entertainment programs, from talk shows to TV series, all have greatly enriched people’s leisure life. When assessing the impact that certain media have on public audiences, we must recognize that TV is the more "socially accepted" media with greater appeal to us than radio. So is there anyone who can deny the importance of TV even in this fast- developed century Unfortunately, a television’s picture is only as good as the broadcast it’s receiving, and even the world’s best televisions cannot make up for a weak or distorted signal. Antenna technology has not kept pace with television design, and the rabbit ears from the 1950s are not far removed from what’s available today. Well, there’s finally been a quantum leap in the design of antennas, and it’s the result of two patented components developed by scientists. These improvements are the secret behind Emerson’s revolutionary new antennas.
Cable subscription solves the problem of getting the signal to your television, but storms and other factors can result in cable outages. If you prefer not to pay the rising monthly fees for cable or live in an area where it’s not available, your picture is likely to be weak, undefined and distorted.
One way to improve your reception would be to mount a large antenna on you roof. Unfortunately, most roof antennas are not particularly pleasing to the eye and may even be prohibited in the area where you live. Rabbit ear antennas don’t improve your picture to any great degree and make your room look like something from an earlier decade. Most antennas need to be aimed at the source of the broadcast and require tuning mechanisms to pick up the signal dearly.
Whether you live miles out in the country or in a concrete building next door to a broadcast tower, bad reception can rob you of the definition and color you were intended to see. The Optima antenna gives you the signal-grabbing power of a large antenna in an unobvious, low-profile size.
In the past, creating an antenna with optimal (最佳的) reception meant making it big, with a large amount of surface area. This resulted in products that were large and unattractive or small and ineffective. Either way, the aesthetic look of your room or house suffered. Research and development tended to focus on the television, not on signal reception...until now.
Recently, a brilliant scientist in Colorado developed an antenna that would maximize reception without being overly conspicuous. Emerson, a leader in electronic technology, has now made this innovation available to the public.
At a lab in Colorado, they developed two patented design improvements that made the Optima antenna possible. First, they created a flexible circuit board with a serpentine (弯曲的) antenna, resulting in a large surface area confined to a small space. Second, they developed a technique that converts the copper shielding on the attached cable to an additional signal receiver. This greatly enhances the antenna’s reception power and allows you to tune the antenna by simply moving the cable! The antenna works best at a range of up to 30 miles from the signal source. We recommend an amplifier for reception up to 45 miles away. Ask your representative for details.
The handmade assembly is encased in aircraft-grade plastic and high-density foam. The weather-resistant cover is a neutral white and can be painted to match the color of the house or room. Plus, the omni directional (全方位的) design allows you to mount the unit anywhere you please. The Optima’s universal design makes it adaptable to any component, and installation is a snap (迅速，容易). So sit back, relax and enjoy the dearest picture you can get from your television.

Attention mini-dish owner: If you own a mini-dish satellite system, you are aware of the off-air issue and are probably wondering how you can pick up local broadcasts. After all, .what good are hundreds of channels if you can’t find who won the local city council election. The Dishmate harnesses the same technological innovations as the Optima TV antenna to give you a powerful omni directional antenna that is virtually invisible. It is compatible with a variety of systems and is easy to install.
The headquarters of Emerson is located in Colorado.
