WiFi Omni Directional Antenna – 12dB Wireless

The 12 dB WiFi Omni Antenna are sleek and effective addition to your wireless network. This antenna is very popular with wireless installers, setting up outdoor commercial wireless networks to extend the range of access points, bridges and routers.

Radiation Pattern - WiFi Omni Antenna

Omni-directional WiFi Antennas, provide 360 degree coverage, but as gain increases, the vertical radiation pattern decreases. Shown here, is a visual representation of the 8dB, 12dB and 15dB antennas, showing the decrease in vertical WiFi pattern as gain increases.

This Wireless / WiFi Antenna, is the best quality omni manufactured, and has very reliable gain factors, never deviating from antenna to antenna. These omni-directional WiFi antennas, pair perfect to all outdoor WiFi access points, such as RadioLabs o2Surf, or, to Powerful, outdoor WiFi Access point system.  RadioLabs manufactures and offers numerous WiFi access points for indoor and outdoor use. These omni antennas, are the highest quality antennas offered on the market, and are commercial rated. They are suitable for a decade of more of outdoor use, are fully waterproof. Made of a thinwall fiberglass, multi-stacked dipole antenna, they have excellent signal quality, amazing range, and after testing almost every WiFi Omni on the market, nothing else even came close to our 8, 12 and 15dB antennas.

RadioLabs customers have used these antenna for years and RadioLabs has used these in our own tests since initial product release, and even with changing atmospheric conditions, salty coastal air of both Northern California, and now in North Carolina, the original. There was some corrosion on the threads of the U-Bolt, but easily came off with Steel wool. The aluminum mounting tube, is made out of high quality anodized metal, and is built overkill for its intended purpose.

Update: 11/5/19 Customer called in – Original purchase date, March 2003 with one of our first customers to purchase this very antenna. She called in to simply order a new WiFi Coaxial Cable to upgrade to our o2Surf, but reports her antenna has worked flawless now for over 16 years. There are no other antennas on the market, for any price, that RadioLabs could manufacture or sell that provide excellent results in an outdoor antenna for this price.

RadioLabs History with WiFi Omni Antennas

When we opened our shop downtown back in 2001, RadioLabs originally bridged our old shop location, to our downtown location here in our small town. This was before the WiFi band was cluttered with hundreds of WiFi access points and home routers every 10 feet. Two of these same antennas provided a dedicated wireless bridge system for years.  WiFi became so popular, that RadioLabs could no longer use omni-directional antennas for wireless network, inside of our town, so we were eventually forced to go with a dedicated wireless bridge system.

How Far will my WiFi Omni Antenna Broadcast?

We are often asked on an almost daily basis, how far one of these antenna will reach. Well, there are a number of factors involved in this, mostly due to the wide variety of specifications with WiFi / Wireless equipment, the amount of power on both ends, and, even more important than power, the receiver capabilities on both sides of the link. Generally, the limiting factor for all wifi / wireless systems, are dependent on Well, it’s safe to say, with 2 of RadioLabs o2Surf outdoor radios they are capable of bridging or linking together at 5 miles or more.. However, this is not realistic. Our customers report they can see our WiFi Omni Access Point Kit, at over 6000 ft, and we have confirmed here in our new North Carolina Location, that we can connect back to our omni, on a cell phone at over 2000 ft at full signal strength.

Installing a WiFi Omni-Directional Antenna

N Female Connector - Requires N Male on Coax

Like all of RadioLabs antennas, we feature an N Female connector on the this antenna

These 12dB Vertical antennas, work on any 2.4 GHz router, Access Point, or outdoor radio. If you have one of RadioLabs o2Surfs, or an older router, or whatever your application, you simply need either a 2 ft coaxial cable, to go to the top of one of our o2Surfs, or RadioLabs can custom build you a cable to your exact length. Do not use these omni antennas with any type of coax cable. There are some companies, selling cheap coax cable on big retail websites, advertising it as “WiFi grade cable”. We have seen this cable and they are using low frequency, high loss cable and selling it to customers who know nothing about coax cables. These coaxial cables being sold to customers, have horrific loss factors and essentially attenuate (reduce) the signal quality in just a mere 5 ft, or, even worse, we’ve seen companies selling RG-59, 75 ohm TV grade coaxial cable. We only recommend our LMR – RL-400 WiFi Coax cable for any antenna installation. Our coax is ultra low loss, only degrading the signal a mere 0.07 dB per foot. So, in a 2 ft span, the loss is almost not calculable and in a 20 ft run, the entire coax only reduces the signal by 1.4 dB, plus 0.3 dB loss per connector, so the total loss calculations on a 20 ft coax, going to our omni antennas is measured at 0.3 (per connector) x 2 = 0.6 dB + 1.4 dB (cable) = 2dB loss for a 20 ft cable. This is excellent.
If you’re using our excellent, commercial grade WiFi Omni , followed by cheap, very high loss coax, it will degrade your signal more in just a mere 5 ft, than any gain achieved by our antennas. NEVER skimp on Coax Cable. It’s a make or break situation!

For the easiest installation, please use RadioLabs WiFi Antenna Mount!

To really maximize your wireless bandwidth an antenna is vital, and this antenna is one of our most effective for extending your signal in all directions. You can easily set this antenna up and create a multi-point wireless network, or to distribute your high speed throughout your neighborhood.

The High Gain 12 dB Wireless Network Antenna is constructed from sturdy, tight-weave fiberglass and enamel coated. If mounted properly on a sturdy mast or tower, the 12dB commercial omni can withstand extreme wind speeds in excess of 130 ++ MPH.

By simply looking at this antenna, you will realize that this is the finest quality 802.11 omni antenna on the market. The mounting bracket is constructed from machined aluminum and the “U” clamp are corrosion-free stainless steel.

Mounting Tube, aluminum brackets and U-Clamps included!
