Diamond NR-770 HSP · Product source ↗The NR-770HSP is a spring-base dual-band mobile antenna for 144 and 430 MHz. Diamond describes a radialless design: a half-wave on 2 m and two stacked 5/8-wave elements on 70 cm. The spring base permits mechanical deflection.
Its PL connection fits the linked Sirio MAG 145 PL base. The antenna is one metre long and additionally supports reception in the 300 MHz band. Its power-handling rating describes the antenna, not the output of the attached radio.
