Optusantennas and aerials for house roof mounting 3G yagi

Most issues with slow wireless broadband or bad phone reception are solved with a roof mounted antenna. If you've located your nearest cell tower, the next step is a breeze.

Which type do I need?

There are two main types of roof antennas - omnidirectional (collinear) antennas, and directional (yagi) antennas. Omnidirectional antennas are designed for areas around town or in the suburbs where there are often several cell towers within range. This antenna leaves your mobile to decide which tower offers the best signal. However you'll notice as they spread their power over a 360° range, they do not receive as strongly as their yagi counterparts.

Directional, or, Yagi antennas are the much more popular choice as their high power provides the strongest increase of all antenna types. The trade-off here is that they require aligning in the direction of the cell tower - the higher the dBi gain, the more precise you will have to be. In deciding between yagi models, the wider angle of the 12-14dBi antennas make them more suitable for hilly areas and areas with dense vegetation, with the 14-16dBi antennas more suited to very long range connections with less obstructions.

There are typically three to four Optus 3G antennas that we recommend for improving mobile phone and 3G internet service based on the terrain, vegetation, and distance to the base station. The other antennas listed here are suited to more unique situations.

It's also worth mentioning that all these antennas need to be plugged in to either a Smart Repeater to broadcast phone service inside the building, or connected directly into your modem or mobile phone with a patch lead.

As for improving Optus 4G internet service we recommend you use the following page 4G Antennas. The below list should provide some general guidance.
