Australians watch an average of 670 hours of television per year!* It makes sense then to invest in a great quality entertainment system. The ongoing technological advancements in televisions are amazing, but not many people understand that amazing tech means diddly-squat if you don't have a good quality antenna. If you're considering investing thousands in a new television, then you're mad not to invest in a new antenna. It'd be like buying a Porsche then fitting it with old tyres!
The most common reason for poor TV reception - other than geographical location - is poor antenna quality and/or poor antenna installation. Antennas 'catch' radio frequency signals which have been transmitted from a television transmission tower. These signals are then converted to an electric current which is sent to the TV to reinterpret into a picture. TV picture quality can only ever be as good as the signal it receives from the antenna. So you could say antennas are very important!
It really depends on your configuration and what kind of television programming you want to view. Generally, if you want to be able to watch all free-to-air television channels, you will need to have an antenna. Cable and satellite television set-ups can receive some free-to-air channels - however availability is based on your set-up, chosen service and location. Therefore, if you have a cable or satellite service installed and are happy just having whatever free-to-air channels you can get, then you may not require an antenna for your set-up - but your cable/satellite provider should be able to advise more specifically to your particular case.
Australia's television transmission signals are digital (Australia's analogue transmission signal was switched off in 2013). So first and foremost make sure your antenna can receive digital signals. You also need to make sure your antenna's band and channels marry up with your location's transmission specifications. In Australia, signals are transmitted on VHF band 3 (channels 6-12) and UHF band 4 & 5 (channels 28-51). As a general rule, high density metro areas work off a VHF signal, and regional low density areas work off a UHF signal. If you're not sure about your area's specifications then be sure to visit: myswitch.digitalready.gov.au.
Antennas are either UHF, VHF or a combination. In high density areas, VHF (Very High Frequency) antennas are recommended as their signal responds better to obstructions. The signals aren't very powerful but ample enough to cover the shorter transmission distances required in metro areas. UHF (Ultra High Frequency) antennas are widely used throughout regional areas where the transmission distance is longer and obstructions are fewer. UHF signals are much more powerful so transmissions can be picked up with smaller antennas. Generally the choice between VHF and UHF has been made for you, based on where you live. If you live on the cusp of a metro area then a VHF/UHF combination antenna (such as Jaycar's LT3195) is a good choice as it covers both options.
Elements are the visible rods/poles/cables of the antenna that receive the transmission and convert it to electrical energy for the TV. Generally speaking, if your antenna has more elements it will generate a stronger electronic signal (and will cost more). Element lengths are very precise and specific in their physical position on the antenna. Again your geographical location will determine the number of elements you should invest in. Jaycar's 6 element VHF antenna (LT3161) is ideal for metro areas, whereas the 42 element UHF antenna (LT3181) is suited to medium semi-regional signal reception areas. If your closest neighbour is a good 10km drive away, then you'll want to consider the 91 element UHF antenna (LT3182). It's a huge 2 metres but great for picking up signals transmitted far, far away!
Antennas need to be installed facing the closest television transmission tower and clear of obstacles - such as trees or other buildings - which could affect the transmission signal. If you're simply replacing an old or broken antenna then you should be able to do it yourself, especially as it's likely you already know which direction the antenna needs to face. If you're installing a new one then look at how neighbours have placed theirs - they've done the hard work to get the best signal so just copy them! If you can't see what the neighbours are doing, then you can use Jaycar's Signal Strength Meter (LT3332) to take the guesswork out of the process. If climbing up and down a ladder isn't an attractive proposition, then bring in a professional! Often you can buy the antenna, and then get someone more sprightly and unafraid of heights to do the hard work for you.
Not really. Since Australia moved to a digital signal, anyone with an old analogue TV would already be using a digital set-top box to 'interpret' the digital signal for their TV. However, don't be disappointed if your new antenna makes no difference to your picture quality! Your system will only ever be as good as the weakest link, which in this case would be your analogue TV.
Antenna deterioration is not a case of if, but when. Because they are outdoors, they put up with a lot of punishment from both weather and wildlife. If your television's display suddenly deteriorates, you should definitely conduct a visual inspection of the antenna to check for quality issues or broken elements. Of course sometimes that's easier said than done. Stand alone buildings will have their own antenna, while multi-dwelling units - such as apartment blocks and townhouses - use a shared antenna system. If you live in the latter, you'll need to liaise with your body corporate or landlord about the issue.
We do offer a range of indoor antennas at Jaycar but they're really only going to deliver a result in high-density areas with close proximity to a TV tower. Be warned: their effectiveness at picking up a signal can be hindered by wall insulation, plumbing, electrical wiring, roofing materials and even people. An indoor antenna can be a worthwhile investment but there are many variables with few guarantees. Jaycar's Indoor Desk or Wall Mount Antenna (LT3116) is economical enough to warrant experimentation. It's worth a shot, especially when your viewing pleasure is at stake! If it doesn't solve your particular reception issues, you're welcome to return it to the store for an upgrade or refund within our conditions - no trouble at all!
