PREMIUM COLD WELD YAGI ANTENNAS FOR SUPERIOR PERFORMANCE AND VALUE Our Yagi antennas are used by customers all over the world. They are used in the oil industry for off shore drilling rigs and in locations where resistance to severe environments is a great cause of concern. They are used by telecom carriers that demand total reliability. Since 1978 Comtelco (now a Mobile Mark brand) has shipped over 100,000 yagis worldwide. By using a construction technique called cold weld, we can produce antennas that are every bit as rugged as a standard welded yagi, but at a significant cost advantage. Using specially designed hydraulic machinery, we are able to press tight tolerance solid elements into precisionmachined booms. These elements are pressed in with over 1,000 lbs. of hydraulic pressure insuring a permanent bond. After assembly, an epoxy powder coat is applied. This seals the antenna, providing total environmental protection. Our basic yagi design is common to both our standard duty and heavy-duty versions. The standard duty “22 series” yagis are built using 1/2” U channel booms with 1/4” solid elements. The heavy-duty “33 series” yagis use 1” U channel booms with 3/8” solid elements. Both series have a no-tune balun assembly and epoxy powder-coated finish. • Stainless steel mounting hardware • 300 watt power rating • 125 MPH wind survival rating • Stainless steel mounting hardware • 300 watt power rating • 125 MPH wind survival rating When a fully welded Yagi with an enclosed feed is required, the Y66 series will fill the need. These antennas are available in standard and log periodic versions. They feature the same solid elements as our heavy duty Y33 series yagis. These yagis have been designed to meet the rigid requirements of the positive train control system.
