Telrex® Log Periodic Antennas are produced exclusively by DX Engineering for a variety of Commercial, Military and Industrial, specialized and demanding applications. Telrex® Antennas are engineered using state-of-the-art design methods, are machined with maximum precision, and are manufactured with the finest materials available. Simply stated, Telrex® Antennas fulfill the company philosophy of being "The Best Antenna Available".
Telrex® Log Periodic Antennas offer superior gain, high front to back ratios and very low SWR across the entire frequency range of the array.
As shown, model TEL-143042-135 antennas are custom designed to cover 14 through 30 MHz, featuring 16 elements on a 42 ft. long, 3 in. diameter extra-heavy duty boom. Multi-dimensional boom support systems secure these rugged LPDA with RF transparent, 6,700 pound breaking-strength Phillystran™ guy line. Featuring self-supporting, large diameter reinforced elements, these antennas are built to achieve 135 mph wind survivability per the EIA-222-C Specification. All structural parts and elements of these antennas are made from 6061-T6 aluminum and stainless steel.
The Telrex® model TEL-143042-135 longest elements are 36 feet long, and have a turning radius of approximately 27 feet 8 inches, with a wind load of approximately 22 square feet. These antennas are made to handle 10 kW or more, depending upon the user requirement. The DX Engineering balun supplied will handle 5 kW CW and 10 kW SSB, with higher power baluns available.
Excellent performance of TEL-142042-135 antennas includes average free space gain of 7.5 dBi, front-to-back over 25 dB and SWR under 1.5:1 across the entire operating frequency range of 14 through 30 MHz.
A 3 inch O.D. mast with a high-end rotator, or a rotating tower, is strongly recommended for the TEL-143042-135, which weighs over 350 pounds. For the proper crane installation of Telrex® Antennas, DX Engineering recommends XX Towers, Inc., with worldwide installation experience and capabilities.
Telrex® Antennas offer rotatable and fixed Log Periodic and Single Frequency Yagi antennas, with customized gain performance and enhanced wind survival to achieve the institutional customer's specific objectives, creating an unsurpassed HF directional antenna system.
