Technician exam question T9B06
Subelement T9, ANTENNAS AND FEED LINES· Group T9B
Which of the following connector types is most suitable as an RF connector for frequencies above 400 MHz?
- A.PL-259
- B.Type N (correct answer)
- C.RS-213
- D.DB-25
WhyType N is the connector type most suitable as an RF connector for frequencies above 400 MHz. Type N connectors are built with a more precise, weatherproof design that maintains a consistent impedance well above 400 MHz, making them well suited to higher-frequency work, answer B. PL-259 connectors (A) have an impedance discontinuity that becomes a problem above a few hundred megahertz, and RS-213 (C) and DB-25 (D) aren't RF connectors at all, RS-213 isn't a connector standard and DB-25 is a computer serial/parallel port connector.
