The Sirio SD 1300 N is the N-connector variant of Sirio's professional-grade SD 1300 discone base station antenna, engineered in Italy for wideband receive and multi-band transmit use. Identical in performance to the SD 1300 U, it features an N-Female connector for lower-loss feedline connections — making it the preferred choice for installations using LMR-400, Ecoflex, or other N-type coax. With a receive range of 25–1300 MHz and transmit capability across CB 27MHz, 6m HAM, 2m HAM, 70cm HAM, VHF Airband, VHF Marine, AIS 162MHz, TETRA, LTE-450, 4G-LTE, and ISM/SIGFOX/LoRa 433MHz, it handles up to 300W VHF and 200W UHF. Standing at 1600mm (5.25ft) and built from chromed brass, stainless steel, and nylon. Key Features Receive: 25–1300 MHz wideband coverage Transmit bands (@ SWR ≤2): 49.5–50.5, 120–180, 215–300, 415–465, 610–650, 710–1000, 1130–1300 MHz Compatible systems: CB 27MHz, 6m HAM, 2m HAM, 70cm HAM, VHF Airband, VHF Marine, AIS 162MHz, TETRA, LTE-450, 4G-LTE, ISM/SIGFOX/LoRa 433MHz Max power: 300W VHF / 200W UHF Gain: 0 dBd / 2.15 dBi at lowest frequency N-Female connector — ideal for low-loss LMR-400 / Ecoflex coax installations Omnidirectional radiation pattern Linear vertical polarisation Discone design for exceptional wideband performance On-mast mounting Height: 1600mm / 5.25ft Premium materials: chromed brass, stainless steel & nylon Made in Italy by Sirio Technical Specifications Type: Discone base antenna Radiation: Omnidirectional Polarisation: Linear vertical RX frequency range: 25–1300 MHz TX bands (@ SWR ≤2): 49.5–50.5 / 120–180 / 215–300 / 415–465 / 610–650 / 710–1000 / 1130–1300 MHz Max power: VHF 300W / UHF 200W Gain: 0 dBd / 2.15 dBi (lowest frequency) Connector: N-Female Height: 1600mm / 5.25ft Mounting: On-mast Materials: Chromed brass, stainless steel, nylon Country of origin: Italy
