CMC (continued from page 23) broadcast reception at sea. More than 15,000 Naval aerials and some 1,200 shipboard distribution systems have been installed worldwide. With a well-estab- lished network of representatives in 30 countries with 300 depots, the Swedish company can provide fast delivery and reliable service in most ports throughout the world. The equipment manufactured by Naval Systems, including omni-di- rectional antenna systems that are best for TV reception at sea, is designed strictly for marine appli- cations, and will withstand high winds, iceloading, salt water spray, and the shock and vibration that are present in the marine environment. Naval Systems antennas are made of ABS plastic with circuitry and headamplifiers built into pol- yurethane foam. Mounting bases of seawater-proof special alloy, and bolts of acid-proof stainless steel insure long operational life. Spe- cial wavetraps and arresters pro- tect the amplifiers from HF over- loading and breakdown due to static charge. The aerials are tested by Det norske Veritas for the same approval as for radar equip- ment, and by FFA for severe wind loads. COMSAT Circle 35 on Reader Service Card COMSAT Maritime Services of Washington, D.C., provides tele- phone, telex, and data services to the international maritime mar- ket through the INMARSAT sys- tem. The firm's services are listed below. Telephone. High-quality tele- phone service is fully intercon- nected with the worldwide tele- phone network. Service is fast, reliable, and private. Service fea- tures include direct-dial calling with one-minute minimum, sta- tion-to-station and person-to-per- son calls, collect calls, credit card calls, and conference calls. Telex. Standard telex services (66 words per minute or 50 baud) are interconnected with the world- wide network through COMSAT's Telex Switching Center in Wash- ington. Any office telex machine in the U.S. or abroad has a direct link to ships and offshore facilities with ship earth stations. Service features include store and for- ward, multiple address, depart- mental billing, and other options. Facsimile. Using a telephone circuit, both analog and digital facsimiles of manifests, drawings, daily reports, weather maps, well logs, and other graphic materials can be exchanged between com- patible telecopier machines on ship and ashore. Voiceband Data Services. Using voice channels, data communica- tions are available typically at data speeds of 300, 1,200, and 2,400 bits per second. High-speed Data. Data at 56 kil- obits per second is available in the ship-to-shore direction. A voice channel can be used for coordina- tion purposes. Service is provided to COMSAT coast earth stations for interconnection with customer- arranged U.S. domestic links. DANMAR Circle 36 on Reader Service Card Danish Marine Communications A/S (DANMAR) of Denmark re- cently introduced its RT-210 se- ries, a new generation of HF/SSB radiotelephones that breaks away from many traditional operating and technical concepts. One feature of the RT-210 is that all operations and adjust- ments are carried out from a small control unit that can be up to 160 feet from the rest of the radiotele- phone station. The RT-210 is a solid-state, 400- watt PEP, full duplex transceiver based on digital frequency syn- thesis. The transmitter part covers the frequency band from 1.6 to 30 MHz in 400 programmable chan- nels, or free frequency selection in (continued on page 26) HIGH SEAS COMMUNICATIONS Another is that we can deliver this gear at prices you just can't ignore. Like, for example, a full 400 watt SSB radiotelephone for about as much as you'd expect to pay for half the power. Another reason is modularity. With our extensive equipment line, you can go from a basic radiotelephone to virtually any level of communications systems desired. Add telegraphy; telex, even fully automatic; go to a full Solas main <„* ship station. And, of course, all of this equipment is FCC type accepted/approved. You can build a little or a lot. When it comes right down to the most communications for your dollar, it becomes very hard to beat a system from Radio-Holland. One reason is that we are exclusive distributors for the Sailor line of high quality communications equipment and Philips SITOR systems. » , T „ i -§ J0« » >MUM mm g = - * •r — - "T^J- . z. r Z.
