The Diamond SRJ795 is a high-grade wideband telescopic antenna engineered for handheld transceivers, communications receivers, and portable radio scanners. Manufactured in Japan to Diamond Antenna’s rigorous quality standards, it delivers wide continuous reception coverage across the 70 MHz to 1000 MHz (1 GHz) spectrum, offering a substantial improvement in gain and weak-signal acquisition over standard rubber duck antennas.<\/p>\n

Fitted with an SMA-J (SMA Female) connector base, the SRJ795 is designed for direct screw-on mounting to walkie-talkies and scanners that feature an SMA Male chassis post. It features a multi-section telescopic mast that extends up to 113 cm (44.5 in) for maximum aperture and collapses down to just 17 cm (6.7 in) for safe transport. Electrically configured as a 1\/4-wave radiator across 70\u2013300 MHz and a 5\/8-wave element across 300\u20131000 MHz, it delivers 2.15 dBi of gain and supports up to 10 W FM transmit power.<\/p>\n

\n

Recommended Applications<\/h2>\n

Wideband Scanner and Receiver Monitoring<\/h3>\n

Significantly improves reception sensitivity across civil and military aviation airbands, VHF\/UHF public services, amateur radio bands (2 m \/ 70 cm), marine traffic, and utility systems up to 1000 MHz.<\/p>\n

Field Communications with SMA-Male Radios<\/h3>\n

Provides a direct, secure connection on transceivers with SMA Male chassis studs, eliminating signal attenuation and bulk caused by aftermarket RF adapters.<\/p>\n

Portable Emergency and Field Kits<\/h3>\n

Retracts to 17 cm for easy packing in emergency kits, backpacks, or tool cases, extending to 113 cm whenever extended range is required.<\/p>\n

\n

Why Choose the Diamond SRJ795?<\/h2>\n

The primary advantage of the SRJ795 is its integrated SMA-J connector, tailored specifically for radios where the chassis terminal has external threading and a central pin. Its precision brass telescoping sections provide smooth extension and low contact resistance, allowing users to physically adjust element length to match operating wavelengths, thereby optimizing VSWR and minimizing background noise.<\/p>\n

      Frequently Asked Questions<\/h2>\n

      What is the difference between Diamond SRH795 and SRJ795?<\/h3>\n

      The sole distinction is the connector base: the SRH795<\/strong> is equipped with an SMA-P (SMA Male)<\/strong> connector, while the SRJ795<\/strong> features an SMA-J (SMA Female)<\/strong> connector, designed to fit transceivers that have an SMA Male chassis post without requiring external adapters.<\/p>\n

      How should the antenna length be set during operation?<\/h3>\n

      For wideband reception and scanner monitoring, extending the antenna to its full 113 cm length provides optimal signal capture. For transmission on specific VHF or UHF amateur frequencies, adjusting the number of extended sections to align with the target resonant wavelength helps achieve the lowest VSWR.<\/p>\n","protected":false},"excerpt":{"rendered":"
