Re: TV antennas
Mac, You want a digital antenna because analogue is shutting down next year. There is nothing very different about digital antennae. Instead of having to cover channels 2 to 10 and the lower UHF channels, which is what the stations use for analogue TV, you only need VHF channels 6 (Channel 7's digital services) to 12 (ABCs digital services) and the lower UHF channels (SBS and WestTV digital services). The higher the channel, the higher the frequency and the lower the wavelength. Thus the shorter 'arms' of the digital antennae. I suggest one of the following Hills antennae: SMX14B4+ SMX24B4+ Both are fairly well constructed and work best with VHF channels 6 to 12, and UHF channels 28 to 50. All existing digital Perth digital TV stations and future capital city stations will broadcast in this range. The frequencies allocated to digital radio also fall in this range. Only country and infill transmitters use higher UHF channels, and then use UHF only. The smaller SMX14B4+ has less gain than does the bigger SMX24B4+. Both would be very adequate for reception in Woodlands, but if you are considering several branches to rooms the higher gain of the bigger model may be a good idea. I have just successfully installed a SMX14B4+ antenna in a friend's house near Woodlands. They have only 1 outlet. They have a tiled roof and no metallic sarking, so I installed the antenna inside the roof space so it is protected from the elements. Should last for a very long time. Got excellent signal strength on all 6 digital TV transmissions; which are Ch 6 for the 'Channel 7' sub channels, Ch8 for the 'Channel 9' sub channels, Ch11 for the 'Channel 10' sub channels, Ch12 for the ABC sub channels, Ch29 for the SBS sub channels, and Ch32 for the West TV sub channel. Note that I list the actual broadcast channels, and not the silly, illogical, 'logical channels' that the broadcasters use for illiterate consumers.

Re: TV antennas
OK, I stand corrected. But I was not suggesting that a poorer antenna was as good, only that the wide bars on the old antennas were not needed -- I was under the impression that the bar lengths were a reflection of the signal wavelengths to be collected, and that if you were using only digital TV (broadcast on higher frequency, shorter wavelength) and no longer needed analogue (longer wavelength), you did not still need a wide-bar antenna. But I'm pretty ignorant in this area, I only wanted to comment that a user should check if they still needed analogue (some parts of WA are still without a digital signal).

Re: TV antennas
hello David ch7 9 are in the 190mhz range thus you still need the longer rods, just fitting an sbs type yagi antenna may reduce the reception quality of the commercial channels, it is correct that the bar length has to match the frequency for good reception James SAD Technic U3 6 Chalkley Pl Bayswater WA Australia +618 9370 5307 mob 0414 421132 (international +614 14421132) sad...@iinet.net.au http://www.members.iinet.net.au/~saddas/ Patience and perseverance have a magical effect before which difficulties disappear and obstacles vanish.

But I was not suggesting that a poorer antenna was as good, only that the wide bars on the old antennas were not needed -- I was under the impression that the bar lengths were a reflection of the signal wavelengths to be collected, and that if you were using only digital TV (broadcast on higher frequency, shorter wavelength) and no longer needed analogue (longer wavelength), you did not still need a wide-bar antenna. But I'm pretty ignorant in this area, I only wanted to comment that a user should check if they still needed analogue (some parts of WA are still without a digital signal).

Re: TV antennas
Hmmm Very interesting - and I wouldn't want to argue with your facts - however, it doesn't really reflect my experience. I only have the rabbit ears type indoor antenna and analogue reception was (to be expected) poor/hard work so I was expecting to NEED an external antenna when I went digital. However, to my surprise I can get digital OK :o) Tuning the antenna is trickier since the digital looks perfect until it doesn't - that is the picture starts to pixellate and/or the sound drops in/out. My method, since the analogue digital come from the same transmitter, is to switch the TV to analogue and play with the aerial until I get the best picture (still pretty bad/snowy on SBS) and then switch back to digital and watch my perfect picture. - its then OK till the next time somebody knock the antenna ;o( I do realise it would be better to get a good external aerial (one of these days) but I certainly find, even with my poor antenna, that digital reception is much better than analogue. Note: this is in Albany with just SBS and ABC digital channels - they are just about to FINALLY give us commercial digital channels (not that I've missed them really) so it will be interesting to see in the experience still holds.
