Winsig 3.1 Ultra Plus TV and Broadband Antenna

Integrated Broadband and Terrestrial TV antennas are here!

The Winsig 3.1 Ultra Plus antenna is now available, both as a retrofit kit for Winegard antennas, or as an Original  Equipment fitment for new vans.
  The really great news is that this remarkable antenna can not only provide free-to-air TV, and internet services, it can also enhance your mobile phone coverage, even while travelling.  Whilst this is subject to your chosen carrier and type of phone, it is available to most people. Its called Wi-Fi Calling  (refer to the links below)

Swinburne university antenna test results image


Our recent benchmark testing at Swinburne University has yielded the following comparison to our major competitors.

In each case the setup was identical, and conducted under controlled conditions using a pure sine wave signal generator.

The scale on the left side of the graph (dB micro volts) is a measure of the strength of the signal received from the various different antenna setups.  It is in indication of the type of range that can be expected from a given TV transmitter in the real world.

The actual extra range of our antenna from a given TV transmitter involves the consideration of a number of factors, but we expect this be at least 25% further than that of the Winegard HV.

Are you having problems with TV reception? 

The Australian government Website mySwitch can assist.


This is a great source of information for any given location.  It will provide information such as:
  • Location of nearest television transmission points
  • Polarity and frequency of signal transmissions
  • Coverage map for the chosen area, indicating likely signal quality
  • Antenna setup guide

Horizontal Polarity TV Signal

Television signal polarity - why is it important?

Approximately 60 percent of all television transmitters in Australia are polarise in the horizontal plane (red).  This includes all of our major capital cities (excluding Canberra), and so most of Australia’s homes are covered by these horizontally polarised signals.  By contrast, vertical polarised TV signals (green) are therefore transmitted by 40% of Australia’s TV towers, so why is this done?

Digital television requires a clear line of sight between the transmitter and receiving antenna to provide reliable pixilation free viewing.  If there is an obstruction between the transmitter and your antenna then variable reception results will be obtained.  An obstruction could be a mountain range, or large building....etc.  As a consequence, there are many places in Australia where TV reception from the large horizontally polarised transmitters (such as those in Melbourne, Sydney, Brisbane) have dead spots for TV reception, and so smaller "filler" transmitters are placed nearby to fill in the dead spots.  Now, if these filler transmitters are also horizontally polarised, interference between the two transmitting towers can cause confusion in the signals being received by your TV and thus poor reception.  As a consequence, these filler transmitters are often vertically polarised to prevent this confusion.

Vertical Polarity TV Signal

This is not the only place that vertical transmitters are used however, as the topology of the area where TV signals are transmitted is definitely a factor.  In mountainous areas vertically polarised transmissions can work well in order to fit between the valleys present, and so these vertical signals exist in many country areas.  Notable examples are Canberra, which sits in the valley between the mountains of the Great Dividing Range, and many parts of Tasmania.

So, given that a Caravan, RV or Camper Trailer is designed to travel to all parts of Australia, it is wise to choose an antenna that allows reception of both vertical and horizontal polarised TV signals.  If your current antenna does not feature arrays in both planes, then an upgrade is necessary to ensure worry free TV reception as you travel.
