Technical description NR-770HSP
The Diamond NR-770HSP is a duoband mobile antenna for the bands VHF (2m) and UHF (70cm). Furthermore, it is additionally suitable for reception on 300 MHz.
The NR-770HSP can handle high transmit power (up to 200 watts).
The base is equipped with a PL plug and with a spring instead of an articulated joint. With a weight of 230 g it is one of the lighter antennas of this length.
A big advantage is the "Radial-Less" design, so no additional counterpoise is needed.
The manufacturer specifies the VSWR with better 1.5:1.
Application description NR-770HSP
The NR-770HSP can convince with good gain values on both bands, not least due to its size, and thus also enables stable connections while driving. The spring also "forgives" bumping into obstacles.
Ivan, LU8MIK, informs in a test report about the use of the antenna.
