SQBM500P Dual Band 2m & 70cm Super Gainer Base Antenna 6.8/9.2dBd Gain, 200W, 25-2000MHz RX

The Moonraker SQBM500P Super Gainer is a high-gain, dual-band fibreglass vertical collinear base station antenna for 2-metre and 70cm amateur radio use. With an exceptional gain of 6.8 dBd on 2m and 9.2 dBd on 70cm, it significantly outperforms standard dual-band base antennas — making it the ideal choice for operators who want maximum range and signal strength on both bands from a single antenna. The wide receive coverage of 25–2000 MHz also makes it an excellent wideband monitoring antenna for scanner and SDR use. At 250cm tall with 3 x 19cm radials and 200W power handling, it's a serious performer for any fixed station. Connects via SO-239 (UHF-Female) with a VSWR of 1.5:1 or better.
