Til-Tek was founded by the Tilsten brothers with a clear mission: to build antennas that never fail, regardless of the environment. It began as a hands-on engineering workshop in rural Ontario, where a small team crafted rugged VHF and UHF antennas for Canadian utility and public safety networks. Over time, Til-Tek grew into a specialized RF design and manufacturing company, known across North America for its technical precision and durable build quality
Today, that same commitment to performance and durability drives Til-Tek’s work in the defense, military and broader civilian wireless sectors. The company designs and manufactures high-performance antennas and RF subsystems built to meet the stringent demands of military and aerospace environments, from harsh mountaintop installations and mobile battlefield platforms to airborne ISR systems and next-generation counter-drone products.

Til-Tek’s Approach
We Don’t Resell RF. We Design It.
At Til-Tek, we don’t rely on off-the-shelf components or reference designs. Every product is conceived in-house by our RF engineers and tuned using real-world, physics-first methods. From concept to field deployment, we own the entire antenna design lifecycle.
We start every design with high-precision electromagnetic modeling using industry-leading tools like CST Studio Suite and ANSYS HFSS. Our simulation environment enables
From simulation to physical reality, our in-house prototyping and tuning workflow compresses lead times while delivering high repeatability.
We engineer our antennas to survive and perform in extreme and uncontrolled environments. Our designs are built with zero tolerance for failure in the field.
We adhere to the most stringent design and production standards — not only to meet spec sheets, but to outperform them in deployment.
We deliver RF products that strengthen cellular networks with reliable coverage, multi-band and high-gain performance, and consistent link quality across dense urban and remote deployments. Designed to support LTE and 5G rollouts, our antennas ensure stable connectivity for operators, integrators, and infrastructure partners worldwide.
Our antennas enable wide-area IoT connectivity with optimized performance for low-power devices, sensor networks, and high-density installations. Built for resilience and long-range reliability, they support industrial IoT, smart cities, asset tracking, and next-generation connected ecosystems.
We provide compact, high-performance antennas engineered for distributed antenna systems and indoor coverage applications. Designed for seamless integration, they deliver uniform signal distribution, improved capacity, and dependable performance across offices, campuses, and public venues.
Our antennas support mission-critical SCADA, AMI, and telemetry networks with stable gain, long-range reliability, and rugged construction. Designed for electric, water, and gas utilities, they ensure dependable data transfer for monitoring, automation, and infrastructure control.
We develop high-efficiency antennas engineered for long-range connectivity, enterprise links, and private broadband networks. With strong throughput and excellent interference rejection, they enhance performance across rural deployments, industrial campuses, and wide-area wireless systems.
High-precision navigation depends on RF front-end hardware that can maintain signal integrity across GPS, GLONASS, Galileo, BeiDou, and other global positioning constellations. Til-Tek designs antennas and filters optimized for multi-band GNSS performance, delivering exceptional sensitivity, phase stability, and rejection of adjacent-band interference.
We engineer rugged, mission-ready antennas built for defense, aerospace, and tactical communications. With multi-band capability, robust construction, and high reliability, our systems support soldier radios, airborne platforms, secure data links, and field-proven operational networks.
