www.americanradiohistory.com The Vertex i!.6 DMK Ku Band Uplink Antenna - The Heart of' the !i-if!3 RF System

And one oí the reasonsthere are over 30 Midwest S-23'sin servicetoday. In the U.S.. Italy and Japan.

Over the past year. the Vertex 2.6mDMK outsold all comparable antennas in its class.The reason?

No prime focus antenna can perform as efficiently as the Vertex 2.6mDMK,due to its offsetGregorian teed system.The sub-reflector offers more complete illumination oí the main reflector. and the offsetconfiguration insuresthat the antenna:meetsthe FCC2ºspacing curves, while providing a nominal transmit gain of 50.l dB. Including 4 port diplexer. Crosspolar isolation performance exceeds 36 dB.

Unlike most other mobile antennas, the Vertex 2.6DMKisbuilt to withstand many years of rugged service. A 25" diameter azimuth ring bearing insuresstable mounting ot the antenna while large DC drive motors provide all the power necessaryto point the antenna even during high wind conditions.

It you're considering a mobile satellite system.compare the actual performance measurements oí the Vertex 2.6DMK to any other antenna in its class.Ask the space segment providers which antenna outperforms all others.

Thenyou'll know the reasonsthere are so many Midwest S-23'son the road today. Contact us tor complete specifications and information.

In the politically ho's making broadcast law these days? Our thoughts turned to this question after reading a recent report in The Wall Street Journal. charged HDTV According to the Journal, one proposed House of Representatives HDTV bill is situation, there are being written, not by a representative or an employee of a representative, but no disinterested by an employee ofAmerican Telephone and Telegraph. The author in question, parties. Rhonda Levine, is working under the direction ofRep. Mel Levine, a California Democrat. Her salary comes not from Rep. Levine's budget, however, but from a science and technology fellowship provided by AT&T. The situation is completely aboveboard, with no indication of any wrongdo• ing. Lobbying efforts by industry are a time-honored Washington tradition. Further, Dr. Levine, with a Ph.D. dissertation on the politics of television technology under her belt, seems highly qualified to grapple with the nuances of HDTV legislation. What her current activity underscores, more than anything else, is the com• plexity and politically charged nature of the HDTV situation, where everybody has an axe to grind and there are no disinterested parties. The Levine legisla• tion, cosponsored with Rep. Don Ritter (D-PA), seeks to increase U.S. govern• ment support of HDTV through tax incentives, grants, and antitrust exemp• tions. AT&T, which funds Dr. Levine's fellowship, has joined with Zenith Electronics (developer of the proposed Spectrum Compatible TV high-defini• tion transmission system) to ask DARPA for $13 million in R&D funding. AT&T is also a member of the HDTV consortium recently formed by the American Electronics Association. If anything, AT&T deserves admiration for its foresight in assisting someone likely to be sympathetic to its own agenda. Broadcast engineers, and the orga• nizations that represent them, should take careful note. What group of people is better suited to explain to our legislators the technical and practical consid• erations of new transmission schemes? What group will be more closely af• fected by any changes we adopt? Amid the sea of political, legal and economic considerations that surround the HDTV issue, broadcast engineers must strive to make their voices heard effectively. The future of the industry demands it.

We have become accustomed to the ease and reliability of receiving commercial spots via satellite. We are also impressed with the flexibility of the system in regard to getting refeeds and special feeds. We look forward to a long working relationship.

- Karl Hagnauer KPLR

Our experience at WGN-TV with Cycle-Sat !1asbeen quite positive. The system has been very reliuble and the convenience of receiving the commercials in non-primctime has been helpful in scheduling our tape machines. Our equipment has been freed for production use during the prime hours.

The quality and reliability of the hardware ~nd software is outstanding. It's error free in its operation, and the speed with which we receive commercial feeds saves us make-goods and lost ti~e.

www.americanradiohistory.com WHY WTVH-TV'S BRUCE LEVY LOVES For more than 20 years, WTVH-TV, the CBS affiliate in Syracuse, N.Y, has broadcast HIS its news using EPO remote camera control systems. During that time, the systems have outlasted four sets of cameras-a clear EPO testament to EPO's durability and reliability For most of those years, as Bruce Levy,the production chief at WTVH-TV, will tell ROBOTIC you, the station was virtually alone among American broadcasters.

Now, of course, all that has changed. Ameri• CAMERA cans are beginning to wake up to what their European brethren have known for some time-that EPOCamera Control CONTROL Systems can save them money. Lots of money! SYSTEM. But even EPO Robotic Camera Systems don't last forever. Recently, when WTVH-TV's 20-year-old unit began to show some wear and tear, Bruce Levy confidently ordered three new ones from AF. Associates, thereby continuing his and WTVH-TV's long asso• ciation with the EPO systems.
