Dual 16dbi 1800MHz - Yagi Antenna Kit

 4G LTE 1800 - MIMO mode.
Wireless Broadband

to suit 4G LTE modems with two antenna ports  

These are the same as our 16dBi 1800MHz Yagi Antennas you will see in our other listing.
This Dual Yagi Kit comes with special brackets to allow each yagi to be mounted at +45deg and -45deg polarization, also known as X-polarization (X-Pol) which matches that of the antennas fitted to
4G-LTE Cell Towers.

This provides the necessary "spacial separation" between the two channels used when your modem connects to Full Speed 4G LTE FDD services in MIMO mode (Multiple Input Multiple Output)

Will these antennas suit 4G LTE ?

Telstra and Optus are rolling out 4G LTE services on the 1800MHz band.
 We have 1800MHz Yagis suitable for antennas for 4G LTE. Also, Telstra have their 850MHz DC-HSPA+ 42mbps service (not LTE) that was initially marketed as part of their 4G network.   More detailed info here


Which antenna suitable for My Location ?

what frequency is my cell tower


What frequency antenna do I need, 850, 900, 1800 or 2100 ?

A very high gain yagi antenna (16dBi) will cover only one 3G bands such as 850MHz or 900MHz. The lower the antennas gain, the more bands it can cover for the same size antenna. Thus our mid-gain yagi antennas are suitable for both Telstra/Vodafone and Optus on both bands.

Metropolitan Areas
- All carriers use 2100MHz for 3G/nextG.
- Telstra have 850MHz NextG and DC-HSPA+ in selected metro areas.
- Optus have 900MHz 3G in selected metro areas.
- Vodafone have 850MHz and/or 900MHz 3G in selected metro areas.
- At time of writing, all 4G LTE services use 1800MHz.

Rural Areas

- Telstra use 850MHz for NextG and DC-HSPA+.
- Optus use 900MHz for 3G.
- Vodafone use 850MHz and/or 900MHz.
- Optus & Vodafone often have 2100MHz 3G services in country areas.

Many rural cell towers are utilizing both the 850(900) and the 2100 bands simultaneously to assist them with town and country coverage.

Do I need "Line of Site" to a Cell tower to 3G signal.
Short Answer:
If you have some 3G signal now, these antennas will greatly improve your signal, when correctly installed.
Long answer:
In rural areas using 850/900MHz, some signal may be refracted around hills that would block the higher frequency signals of 3G 2100MHz and 4G LTE 1800MHz. This is why the carriers use the lower frequency in country areas. However the signal you will receive without direct line of site to the cell tower will be greatly reduced. At 2100MHz, direct line of site is a must. But this does not mean you need to be able to see the tower. The 3G signal is absorbed by buildings, trees and other vegetation, but its high frequency waves cannot go through or around hills and mountains.

Where are the Mobile Internet Towers in my area ?

Follow our guide Find Cell Towers Guide to determine the best path to the best tower from your location. Also find cell towers at


What type of Antenna do I need ?

Omnidirectional antennas achieve higher gain by flattening out the "donut".

best gain for 3g mobile antennas
If your constantly on the move you need an antenna that can connect to cell towers in any direction.
Vehicle speed, terrain changes and boat angle/movement effect the angle of the antenna, causing reliability issues with higher gain antennas.

Fixed Wireless Installations:
  Homes, Office and Semi-Mobile

    Directional - Yagi, Panel and LPDA antennas
  - Higher gain, providing more "bars" of signal.
  - Less interference from the side and from behind the antenna.
  - Better Signal-to-Noise Ratio providing better Signal Quality for the
    same Signal Strength of omnidirectional antennas.
  - Possible to connect to more distant, lower signal cell towers that may
    have less traffic load than your closest tower.
  - Must be aimed at the cell tower.
  - Not suitable for Mobile Installations.
  Recommended Antenna Gain
Marginal Signal Areas:
16dBi Single Band Yagi.
Medium/High Signal Areas: 9-14dBi  Multi-band or Dual Band Yagi

  Mobile Installations: Mobile Homes, Caravans and Motor Vehicles
    Omni-directional - (Broomstick and Whip) antennas
  - No need to aim at the cell tower.
  - Ideal for Mobile Installations.
  - Lower gain, providing less signal.
  - Wanted and unwanted signals collected equally from all directions.
  - possible to connect to more distant, lower signal cell towers that may
    have less traffic load than your closest tower.
  Recommended Antenna Gain
Mobile Homes and Caravans: 7-9dBi All-Band Omnidirectional.
Road Vehicle, Metro Areas:
3-7dBi All-Band Omnidirectional.
Road Vehicle, Country Areas:
7-9dBi All-Band Omnidirectional.
Off Road Vehicle, 4WD: 3-7dBi All-Band Omnidirectional.
Marine, Boats and Yachts:
3-5dBi Single/Dual Band Omnidirectional.

Yagi Antenna Gain vs Size Guide


Beware of bogus antennas


ISO9001 Accreditation Certificate

Yagi manufacturer ISO 9001 accreditation certificate

I see other stores sell shorter, higher gain antennas ..
Why are your antennas lower in gain?

Short Answer: We don't exaggerate the performance of our antennas.
There are sellers listing antennas that they claim are 16dBi and even 21dBi gain, yet these antennas are only 1metre long!

For each 3dBi increase in gain, the number of Elements (and thus the total-length of the antenna) needs to double.
For example... a true 3G 850MHz 16dBi antenna must be least 1500mm in length, so 17dBi antenna would need to be about 2.3m and a 19dBi would be more than 3m long.
It is mathematically impossible for
to achieve the gain claimed from such small antennas!
BUYER BEWARE of these resellers and manufacturers that are advertising specifications that are just not possible to achieve.

Important things you should know before purchasing !
 - Know your Carriers Band. Is it 850, 900, or 2100 MHz? 

 - Where are the Mobile Cell Towers located near you?
 - Quality: Is the antenna manufacturer Quality System Accredited ?
 - Antenna Coax Cables: Are the longer cables low-loss or just RG58?
Your Modem.. has it got an external antenna socket?
 - Where will the antenna be mounted? You may need to erect a mast.
   This will be additional cost. . . .

Will this antenna fix my 3G reception ?



I have NO SIGNAL in my area ..
Will this antenna give me 3G reception ?

If others around your location are able to get some signal then, when optimally installed, this antenna will help. One way to find out is to get a High-Gain Yagi Antenna and mount it in the best possible location. Although we don't guarantee this, many of our customers have reported being able to access high speed 3G internet in locations that previously showed no signal bars at all.
Follow our Find Cell Towers Guide for a more scientific approach.

I have WEAK SIGNAL in my area ..
Will this antenna give me 3G/4G reception ?

If you have low and/or unreliable 3G signal using your USB modem inside or outside your building we 100% Guarantee that, when correctly installed, this antenna will greatly improve your 3G/4G signal quality. More info

I have GOOD SIGNAL but my connection is slow and drops out ..
Will this antenna fix this ?

Generally yes, if your problem is due to poor Signal Quality rather than Hardware or Service Provider issues.. these Directional Antennas will improve your 3G Internet connectivity by:
- Reducing interference from areas behind and to the side of the antenna.
- Reducing reflected and refracted signal coming from Buildings and Vehicles.


Where Should I Mount The Antenna?

  Yagi on caravan


Can I mount the 3G antenna on my existing TV mast?

Yes. The same rules for securely mounting any outdoor antenna apply.
1. Mount the 3G antenna at least 250mm from the existing TV antenna.
2. Ensure the pole is fixed securely to the building reducing wind effects.
3. Point the antenna at the Phone tower. The phone tower wont normally
   be in the same direction as the TV tower.

Can I mount the 3G antenna in my roof space?
Any vertical or horizontal pipe, roof edge, wall, balcony railing etc can be used. Also, inside-attic hidden install may be acceptable as long as there is no metal in the roof that signal has to penetrate. RF signals at 824-960MHz) may be reduced by wood and concrete roof structures so avoid mounting inside a building if signal strength is marginal or if mounting a 2100MHz or 1800MHz antenna. The available length of your feeder cable may determine your mounting spot.

I have a 20m tower to mount the antenna, should I run a 20m antenna cable or should I mount the antenna lower at 10m ?

At these frequencies, coax cable loss is a big factor. For every 10m of our low-loss cable, 3-4dB of signal is lost. Consider that if there is only an extra 1dB gain increase at 20m over that at 10m then you could actually loose 3dB of antenna gain by mounting higher. So try it out at 10m. If you get good signal then don't bother raising it. Remember that Signal Quality is more important than Signal strength. On the other hand if you are able to achieve line-of-sight to the cell tower by increasing the antenna height the net gain can be worth while.


Where Do I Point The Antenna ?

 How to mount a yagi antennaHow to mount a yagi antenna


If you haven't already done so, find out which towers are nearest to your location.
You can also determine the frequency (850 900 or 2100) your carrier (Telstra, Optus etc) is transmitting on each tower.

Direct the front of the antenna (usually the thin bit) at the mobile phone tower. The guide linked to above will identify landmarks in he path to the tower from your location and the Azimuth angle of the tower with respect to your position. If using a compass, be aware that metal objects such as a tin roof will upset the compass reading.
satisfactory results may be achieved by rotating your Yagi until best signal is found then centering on the estimated location.
- Slowly rotate the antenna and stop every 10 degrees.
- Wait 30sec's for the Modem's signal meter to refresh. Record signal levels.
- Note the peak and decline positions.
- Determine the centre position between the two decline positions.
- Tighten the mounting bolts.
Stand at least a metre away from and to the back
or sides of the antenna. Never stand in front of the antenna. Your body can greatly alter signal patterns.


How Do Antennas Achieve So Much "Gain" ?

Yagi Radiation Pattern 


Directional antennas such as Log-Periodic and Yagi antennas direct most of their signal in just one direction instead of dispersing all around a 360 degree circle.
Single element whips and rods on cars, boats etc are omnidirectional, radiating in all directions when viewing from above, looking down on the antenna. The longer the the antenna, the more "elements" it has, the higher the gain.

To double the antenna gain (increase it by 3dB) its length and number of elements must double. There are both mathematical and physical limitations to the maximum gain that can be achieved. The 3G and 4G bands are very wide, which limits the maximum gain to begotten from a 'single band' Yagi covering the 850MHz band (824-890) is 16dBi. Likewise, a Yagi antenna designed to cover both the 850 and 900MHz bands (824-960) will be limited to 14dBi. The maximum gain achievable in practice with a Log-Periodic type antenna, regardless of its bandwidth is about 11dBi.



Mechanical Basics of Yagi Antennas ?

YagiVertical-Polarized antenna for
3G or 4G LTE single antenna installs


4G 1800MHz  16dBi aerial
Slant-Polarized antenna for DC-HSPA+ or 4G LTE MIMO

Yagi antenna basics.
Boom: The long horizontal bar that points at the cell tower.
Elements: The small thin rods supported by the boom.
For Single
3G/4G Antenna Installations, mount the antenna with elements vertically positioned, as seen in the pictures. The front of the antenna has the shorter elements and the rear has the longer ones.
Reflector:  Is at the r
ear the boom, This "reflects" the signal forward.
Driven Element: T
he "driven" element  radiates the power from the modem and converts radio waves from the cell tower into electrical voltage.
Directors:  Usually 1 to 15 or more elements specifically tuned to direct signal forward along the boom from/to the driven element.
The signal output is off the front end of the boom.

What is Polarization ?
Radio signals travel oriented vertically, horizontally, circularly or combination's of these. Cellular signals are Vertical or Slant polarized. Your cellular mobile antenna on the car is vertically polarized, for example.
Single Yagi's for cellular must be installed with its elements vertically polarized too. A Dual or MIMO Antenna system for 4G LTE or DC-HSPA 3G connection needs to be Slant-Polarised. See our Dual Yagi Listings.

When to use VERTICAL Polarization.
- 3G and NextG
- Single Antenna systems for 4G LTE and 3G/NextG/3G+ DC-HSPA+ services
When to use SLANT Polarization.
- Dual Antenna systems for 4G LTE and 3G/NextG/3G DC-HSPA+ services
