100-6000MHz omnidirectional antenna waterproof 20×150

In wireless testing, spectrum monitoring, multi-mode communications, and equipment development, a common headache is the need to swap antennas for different frequency bands. The BGS-AN6000-20150B is an extremely broadband omnidirectional antenna covering 100MHz all the way to 6000MHz – replacing multiple narrowband antennas with a single, compact device. It brings exceptional convenience to test & measurement, broadband reception, EMC pre-compliance, and multi-band wireless systems.

Unmatched Bandwidth – Unrivalled Versatility

• Continuous Coverage from 100 to 6000MHz
  Install once and cover VHF, UHF, L‑band, S‑band, C‑band, and more – no more frequent antenna changes. Whether you need to receive 400MHz two‑way radio, 2.4GHz Wi‑Fi, or 5.8GHz video downlinks, this antenna handles it all.
• 360° Omnidirectional Radiation
  Horizontal beamwidth: 360°. Vertical beamwidth varies with frequency (11°–78°). As a broadband receive or transmit antenna, it can serve signal sources from all directions simultaneously.
• Moderate Gain, Balanced Across the Band
  Typical gain range: -6.5 to 4.5dBi. Average efficiency across the full band: approximately 40%. At around 2.7GHz, gain reaches 4.2–4.5dBi with efficiency exceeding 50%. Even down at 400MHz, usable efficiency (≈9%) is maintained. While absolute gain is modest, the extreme frequency coverage offers far greater convenience than narrowband high‑gain antennas for broadband reception, spectrum monitoring, and short‑range communications.
• VSWR – A Wideband Compromise
  VSWR < 3.5 across the entire 100–6000MHz range, providing acceptable return loss. Well suited as a broadband test antenna or general‑purpose receive antenna.
• Linear Polarisation – Widely Compatible
  Linear polarisation works seamlessly with the vast majority of general‑purpose radio equipment, spectrum analysers, signal generators, and transceivers.

Extremely Compact, Rugged, and Durable

• Ultra‑compact Dimensions
  Diameter: only Φ20mm; length: 150mm; weight: just 0.08kg (80 grams). Easily integrated into portable devices, drone payloads, handheld test terminals, or small enclosures.
• Fully Sealed Fibreglass Radome
  Made of high‑quality fibreglass – weather‑resistant, ageing‑resistant, suitable for long‑term indoor and outdoor use.
• Wide Temperature Range & Wind Resistance
  Operating temperature: -40℃ to +80℃; rated wind speed: 36.9m/s (Beaufort scale 12). Handles harsh environments without difficulty.
• DC‑Grounded Lightning Protection
  Internal DC grounding (Lightning Protection: DC Ground) effectively diverts induced lightning currents, improving system safety.

Typical Applications

• Spectrum Monitoring & Signal Reconnaissance
  Paired with a spectrum analyser or receiver for radio regulation, EMC field testing, signal hunting, interference location, etc. One antenna covers everything from broadcast bands to Wi‑Fi.
• Broadband Testing & Laboratory Use
  As a general‑purpose reference antenna in RF R&D and production testing, avoiding measurement errors and time loss caused by frequent antenna changes.
• Multi‑Band Wireless Gateways / IoT Base Stations
  Ideal for multi‑protocol gateways operating Sub‑1GHz, 2.4GHz, and 5GHz simultaneously (e.g., LoRa + Zigbee + Wi‑Fi) – one antenna port serves all bands.
• Drone or Robotic Communication Links
  Its ultra‑light, compact form factor makes it perfect for mounting on drones, robots, or mobile platforms for broadband telemetry or video transmission.
• General‑Purpose Wideband Reception
  Used with SDR (software defined radio), full‑band scanning receivers, broadcast monitoring, and similar applications.
