The RA-2AK is a light weight hand held, directional "H" antenna that has become the standard for handheld applications in the wildlife field. The performance of the "H" is often equal to or better than typical handheld 3 element antennas used in the early days of telemetry. The reason for performance advantage is that the "H" is deployed over the head of the user and the pattern and tuning are less effected proximity to the earth and low vegetation. The result is better range performance and a more consistent pattern for location work as compared to the handheld 3 element antennas. The "H" disassembles to a center "H", two front, two rear elements, and a wooden handle. The RA-2AK is a versatile antenna and can be mounted on aircraft, or as part of an RA-NS Precision Direction Finding System. The K in the part number indicates a "Kit" that includes coaxial cable and carrying pouch.

Service Commitment

Since 1970, Telonics has built a reputation based on product quality, product support, service, and customer satisfaction. Telonics strives to produce the highest quality products, and to support those products accordingly.

Because of extreme conditions and the unpredictable nature associated with most telemetry applications, problems occasionally arise. Most problems can be resolved quickly. In all cases, we hope to be able to work in partnership with users to resolve problems to the user's satisfaction and to uphold our demonstrated commitment to excellence. If problems should arise, all products must be returned to our factory for failure analysis.
