TCI’s HF Antenna Business Still Strong after 50 Years

Fremont, CA – April 2018 – In 1968, TCI opened its doors as a supplier of high-performance high frequency (HF) antenna solutions for broadcast and general communications. While both the HF antenna market and TCI’s product base has evolved over the past 50 years, TCI reports this portion of its business is still a strong contributor to its overall sales base as evidenced by significant orders received over the last six months.

TCI supplies high-performance high frequency (HF) antenna solutions for broadcast and general communications

TCI’s antennas were the first to be designed using proprietary computer modeling tools – a practice that eventually revolutionized the industry. TCI was also the first to provide pre-fabricated antennas and high power (> 500 kW) electrically slewable dipole arrays integral to its highly successful and innovative antenna product line.

Today, TCI supplies antennas to the U.S. Air Force for ground to air communication applications and to other customers for ship to shore communication and shortwave broadcast applications.  TCI also works with numerous non-government customers to provide HF antenna communication systems that minimize timing-latency in various commercial high-speed communication applications.

Owing to the use of high-quality materials and enduring designs, many of the company’s products delivered over its 50-year history are still in operation today.  TCI’s market-leading customer support department is committed to supporting all TCI products and systems to maximize the useful product life for the benefit of its customers.
