Fiberglass Antenna w/ N-female Connector

860-960 MHz 8dBi Omnidirectional Antenna: Fiberglass Weatherproof - suitable for outdoor use

• For LoRa / LoraWAN, Helium, GSM, ZigBee, and any other wireless protocol that uses a frequency in the 850-920MHz band.
• See all 900MHz Antenna options: LoRa, Helium, LoRaWAN, GSM, 3G options
• 915MHz is the middle of the band range of this antenna
• Three versions of this fiberglass antenna:
  • 3 dBi version : This version is better for hilly terrain and/or urban area with obstructions / buildings
  • 6 dBi version: Mid-way between the 3dBi and 8dBi options: i.e., for an area with some hills or buildings / obstructions
  • 8 dBi version that is the subject of the page that you are on : This version is better for long-range in more flat terrain without a lot of obstructions / buildings
• Includes U-bolt mounting hardware for pole-mounting: See more detailed photos here
  • U-bolt set: Inner diameter: 2" Outer diameter: 2 ⅜ "
  • Tube / base cylinder: Outer diameter: 1¼"
  • We also offer the ubolt set and mounting tube / base for purchase as a separate accessory item (though it is included with purchase of this antenna)
• Mounting hardware included: Mounting kit with aluminum tube and U-bolts set is included with this antenna. See details / specifications of the mounting kit. The mount kit is especially suitable for pole mounting
• Rugged and Weatherproof: Fiberglass antenna
  • This antenna's construction features a durable fiberglass radome for durability and aesthetics. Its mounting system features twin heavy-duty mounting brackets and U-Bolts for superior strength.
  • Nickel-plated brass body for enhanced corrosion resistance: Nickel plating is the most weather-resistant, corrosion-resistant metal plating.

Mount Options: See our mount options for antennas with an N-connector (Type-N connector)

Marine antenna : This antenna can be used for marine use, but in a salt-water environment, the antenna often will begin to corrode after a year or possibly less: The chrome plating on the base bubbles and peels off: Our customers that use this antenna for marine use , find that the low cost and fact that it lasts about a year without any issue, in a marine environment, makes it suitable: The antenna is is cost-effective enough even considering that they replace the antenna when the corrosion begins.

Compatibility with wireless standards & applications: This omni directional antenna's range of frequency band compatibility in the 860 MHz to 960 MHz frequency band range, its low broadband VSWR, and impedance matching to 50 Ohm gear, makes it suitable and compliant for all the following applications:

• Compatible with Helium Network miners / devices , as are all antennas in our Helium Antennas subcategory
  • Helium accessory items directory: Antennas, cables & mounts for range-extension of Helium miners (including Bobcat miner) and LoRaWAN access points.
• LoRa / LoRaWAN.
• 900MHzISM Band . Can also be made to operate on other VHF and UHF frequencies within the ISM frequency bands .
• Non Line of Sight (NLOS ): 900 MHz band is best for passing through trees and forests.
• IoT wireless & M2M: Since it is vertically polarized, it is compatible with many machine to machine communication applications, remote monitoring, and telemetry applications:
• RFID
• For 3G / GSM, LoRa, ZigBee, and any other wireless protocol that uses a frequency in the 850-920MHz band.
• SCADA
• Wireless Video Links

ROHS 3 & REACH compliant: Antenna, cable and connector are all compliant with ROHS 3 and REACH.

Technical Questions & Answers:

Q: Why is it 1M in length when a 1/2 wavelength @900MHz is about 16.5cm?

A: Theoretically, the number of arrays without loss of 8dBi is four, and four arrays is 66cm in length. However with the concatenated design, there is much loss, so we lengthen the antenna to 1.1M in order to achieve the higher gain.

Q: How do you achieve +8dbi gain when theoretical gain for a 1/2 wavelength dipole is <2dbi?

A: In order to achieve 8dBi gain, we use a total of seven arrays, so the antenna length is 1.1M.

N-type female Connector Characteristics and Details: Durable, weatherproof connection

• Nickel-plated brass body for enhanced corrosion resistance: Nickel plating is the most weather-resistant, corrosion-resistant metal plating.
• Our N connectors provide a consistent performance from 900MHz to 12.5 GHz.
• N-Female diameter is 0.620-inch (1.57 cm). N-male inside diameter is 0.620-inch (1.57 cm)
• N-connector gender is counter-intuitive.
• N-Type connectors are the largest of the RF connector types, and are usually found on large antennas, especially for outdoor use.
• Our N-Type connectors feature threaded coupling mechanisms and are fully interchangeable with N-Type connectors made to the MIL-C-39012 specification. These connectors are used in all systems where excellent RF and mechanical performance is critical.

N materials composition:

• Connector Body: Nickel-Plated Brass: The most corrosion-resistant of all plated brass alloys (better than gold-plated).
• Center Contact: Beryllium Copper, Gold Plated
• Crimp Ferrule: Copper, Nickel Plated
• Insulators: PTFE

All of our antennas pass QC test before we ship them.
