Diamond X-30-N · Product source ↗The X-30N is a compact vertically polarised base antenna for 144 and 430 MHz. Beneath its fibreglass-reinforced shell it operates as a half-wave radiator on 2 m and a stacked 2 × 5/8-wave arrangement on 70 cm. The N version has an N-female connector at the base.
Its 1.3 m length and short radials suit installations with limited space. The supplied mounting arrangement accepts masts from 30 to 62 mm in diameter. Gain, power handling and wind rating describe the antenna; the supporting mast must be suitable independently.
