Since the introduction of digital television we have found that most household antenna systems/pre-digital are not within the boundaries which digital requires to maintain a constant stable picture. Which means most households will need to upgrade there antenna system before being able to achieve a constant and stable digital picture.
We base our installations on 3 main charactoristics, Cable, Connections and Gain.
Cable, digital requires RG6 dual shielded cable minimum with RG6 quad shielded as preffered to maintain a stable flow of signal transfer.
Connections, the best method of connecting coax cable is to use ftype connectors on cable and with there splitters.
Ftype twist is avaliable for dual shielded and quad shielded RG6 but most common for dual and with quad shielded can be difficult to fit. We then suggest to use a crimping tool and apply ftype crimp connections instead, this tool will cost approx $35 to $50 but will save a huge amount of time and create a stronger more direct connection.
Also keep in mind that with the remainder of you coax cable you are best to use this with some crimp pal plugs to make your own flyleads from the wall socket to your appliances, this means that you have an equal quality cable and connection from start/antenna to finish/appliance.
A guide to fitting connections and stripping coax cable will be covered in another section.
Gain, simply is your antenna supplying enough signal to maintain stable picture, below are basic factors when fitting the antenna.
Antennas will vary from state and country and quality doesn't always mean size, yes a larger antenna will be able to receive more signal but we have installed small antennas with a better success than some large antennas from other suppliers. We would strongly recommened seeking a professional antenna supplier or installer to purchase the best antenna.
Depending on the amount of TV points you are installing and the level of gain your antenna is supplying, you may need to increase its performance. This is done by a mast head amplifier/booster (for instructions on installing a mast head amplifier please see appropriate section).
You want your antenna to have the best shot/line to the transmitter, this means placing the antenna directly in front of a tree etc will affect it's ability to recieve signal. The location on the roof is also important but difficult to find without the aid of a field strength meature so best to base your antenna in the best line to the transmitter remembering a few more metres to the back of the house will make very little difference. The angle of the antenna must be positioned with the front facing towards the transmitter, if the transmitter is not in site and you have no field strength meter check your surrounding neighbours, if there picture is good face in the same direction.
HEHE HAHA, funny to finish on such a basic suggestion (facing simular to your neighbours) but installing an antenna isen't difficult but keeping to the 3 important factors in mind CABLE, CONNECTIONS and GAIN with give you the best chance of a successful installation.
