6.2 dBi 868 MHz Omni Outdoor Fibreglass antenna

Written by EAD Admin on 18th March 2022. Posted in 169 / 433 / 868 / 915 Antennas.

The 6.2 dBi 868 MHz Omni outdoor omni-directional antenna from EAD is centre-tuned and optimised at 868 MHz. Ideal for Helium applications, this antenna is terminated in a N-Female connector allowing it to be connected to a Helium hotspot via custom RP-SMA Plug (Male) cable. For other LoRA, SigFox and LP-WAN applications, the OMNI-868-62 offers consistent and durable mechanical and electrical performance.

Measuring 77cm in overall length (excluding the bracket), the OMNI-868-62-NF is a quality antenna manufactured for permanent outdoor installation. With a fibreglass tube and a robust mounting bracket (including U-bolts for 35-42mm mast diameter) allowing both pole and wall mounting, this antenna is designed for long-term outdoor deployment without degradation.

CFO Compact Fibreglass Omni Outdoor Antenna

Written by EAD Admin on 18th March 2022. Posted in 5G & LTE/4G Antennas.

The CFO Compact Fibreglass Omni Outdoor antenna is a very compact solution providing 4G/5G access. Based around 145mm long Fibregalss sheath, the CFO offers robust performance in a small form-factor.

Operating over a wideband from 617 to 7125 MHz, the CFO covers the majority of 4G/5G frequencies worldwide. It is supplied with a stainless steel L-bracket for wall-mounting and is terminated in a N-Female connector. VSWR across the bands is less than 3:1.

Ideal for 4G/5G access applications, including security, CCTV, telemetry systems, kiosks, vending and industrial cellular deployments, it’s compact size offers a discreet solution whilst the materials use facilitate long-term use without degradation.

Combine the CFO compact fibreglass omni antenna with N-Male terminated low loss coaxial cables to customise your installation.

Helium outdoor antennas things to check before you buy

Written by EAD Admin on 21st October 2021. Posted in News.

The Helium network offering low power coverage across the world is rapidly growing in popularity. Across the world, as Helium miners are being deployed, people are looking at outdoor omni-directional antennas to optimise coverage from each miner installed.

This brief comment is going to focus on build quality.

There are quite a few outdoor antennas on the market, but selecting one with build quality good enough to be permanently installed outdoors without falling apart is critical.

Many low (and very low) cost antennas are available from online market places. Ignoring poor RF performance for now, many of these low cost antennas suffer from poor build quality or inferior materials and are unlikely to survive one average winter outdoors.

Our suggestion is to look for European-manufactured Helium outdoor antennas that tend to focus on quality materials and not solely on price. One particular area to focus on is the sheath or tube as poor materials weather and crack very rapidly leading to unit failure. A proven, durable option is an antenna with a fibreglass tube which will withstand many winter’s deployment without suffering weather or UV-degradation.

Also check the brackets/clamps that come with antenna. Are they fit for purpose? Is the antenna secure enough when mounted?

There is nothing worse than having to replace the antenna you took the trouble to install three months ago due poor survivability of the materials.
