Diamond RH-779 is a wideband telescopic antenna for use with handheld transceivers and scanners. The antenna has a special joint which permits the antenna to tilt up to 180 degrees. The full lenght of the antenna is 113.5cm. When retracted the lenght is 19.5cm. The connector of the antenna is BNC type.

On the base of the antenna a chart is printed depicting the lenght vs frequency adjustment of the antenna. By using the chart you may tune the antenna in any frequency between 70 and 1000MHz. So the antenna is usable not only for transmission and reception in ham radio VHF/UHF bands but also in a really wide range of frequencies (70-1000MHz). You may use the optional BNC to SMA adaptor to connect the antenna to radios fitted with a SMA type connector.
