Sirio SD2000N Discone Antenna vs DPD Productions OmniX Scanner Antenna

Both are wideband scanner antennas with N connectors, but they solve the problem differently. The Sirio SD2000N is a true discone with continuous coverage from 100 to 2000 MHz, so it catches everything from low-band VHF up through 2 GHz, including airband, 800 MHz trunking and 1.2 GHz. The OmniX trades that continuous range for tuned gain on 118-137, 148-175 and 225-900 MHz, needs no ground plane, and owners consistently report it outperforming discones on those scanner bands with sturdier aluminum construction. Pick the Sirio for the widest possible frequency span; pick the OmniX for stronger, cleaner reception on the civil and commercial bands most scanners actually use.

• Choose the Sirio SD2000N if you need one antenna that covers the whole 100-2000 MHz span, including 1.2 GHz and other bands above 900 MHz.
• Choose the OmniX if you listen mainly to airband, VHF public safety and 225-900 MHz, and want gain, no ground plane and a more compact, better-built antenna.
