EVALUATION OF THE TNA-9 AND TNA-10 "TUNABLE SLOT ANTENNAS"
Technical Report
·
OSTI ID:4254102
An evaluation is given of the Bendix Aviation Corporation's tunable slot antennas, models TNA-9 and TNA-10. These antennas were specifically designed as FM/FM telemetering components, tunable within the 215 through 235 Mcs hand of frequencies. The models TNA-9 and TNA-10 are physically small slot antennas which obtain resonance by the use of lumped constants. Compared to a resonant lambda /2 slot antenna, they are inefficient and narrow band antennas. The TNA-9 is a bidirectional slot antenna with a power handling capability rated as 5 watts. The TNA-10 is a unidirectional cavity-backed slot with a power handling capability rating of 150 watts. (auth)
