POLARITY

This describes how the UHF aerial needs to be set up to capture the signal coming from a particular transmitter.  

If your aerial is not the right polarity for your transmission site, you will get occasional reception issues (for example, loss of channels or picture quality), particularly when changes occur - be it changes in broadcast, transmission or weather conditions.

.......................................................................................................................................................................................

HORIZONAL polarity means the X prongs on your UHF aerial should lie parallel to the horizon.

Check your aerial.  If it is set with horizontal polarity (as pictured), make sure that the transmission tower it's pointing to has HORIZONTAL polarity marked against it in the above RF CHART.  This means your antenna has the right polarity.

If you're not sure which transmission tower your is pointed to, check the coverage maps here to see which transmission tower your antenna is likely pointing at.

If you're still unsure, it's time to check with your installer. 

The following RF chart shows frequencies for the multiplexes (MUX) in various Digital Terrestrial Transmission (DTT) Areas. For more information about MUXs, see here.

VERTICAL polarity means the X prongs on your UHF Aerial should be perpendicular to horizon.

Check your aerial.  If it is set with vertical polarity (as pictured), make sure that the transmission tower it's pointing to has VERTICAL polarity marked against it in the above RF CHART.  This means your antenna has the right polarity.

If you're not sure which transmission tower your is pointed to, check the coverage maps here to see which transmission tower your antenna is likely pointing at.

If you're still unsure, it's time to check with your installer.

WRONG POLARITY?

If your aerial polarity is horizontal and your transmission polarity is vertical (for example, if your aerial is pointed at AUCKLAND's Skytower and the X prongs on it are horizontal), then your aerial has the wrong polarity.

You'll need to turn the entire aerial 90 degrees to get correct your aerial polarity.  Consult your installer if you're unsure about doing this.
