DIAMOND SRJ-770 FEM Dual Band Telescopic Antenna 144/430 Mhz SMA Female

DIAMOND SRJ-770

The Diamond SRJ-770 is an original DIAMOND brand antenna, designed to operate in VHF/UHF dual band. The antenna has a female SMA connector on one end, allowing for easy and secure connection to walkie-talkies that have a corresponding male SMA connector.
The main characteristics of the antenna are:
Frequencies: The antenna operates in two frequency bands: 144 MHz in the VHF band and 430 MHz in the UHF band. The antenna gain is 2.15 dBi in the 144 MHz band and 5.5 dBi in the 430 MHz band, which means it provides an increase in transmit and receive power to improve communications range .
Adjustable Length: The antenna is telescopic and can be adjusted to have an extended length of up to 92 cm. When fully retracted, its length is approximately 21.5 cm. This characteristic makes it versatile, since it can be adapted to different situations and needs of use.
The Diamond SRJ-770 is a popular choice for those looking for a high quality dual band (VHF/UHF) walkie talkie antenna with SMA female connector. Its telescopic design and length adjustability allow comfortable and efficient use in various situations. As always, it is important to use original and suitable antennas for the specific frequencies and equipment to obtain optimal communication performance.
