JK200SX Posted April 27, 2007 Posted April 27, 2007 Need to do an antenna install in Camberwell (Halley St). Has anyone had any experience in terms of reception off the Sth Yarra Transmitter? Or is it just better to point to Mt Dandenong? Thanks, John
beeblebrox Posted April 28, 2007 Posted April 28, 2007 Typically if it's digital you will often get a stronger signal from Mt Dandenong that then doesn't require amplificatioin, very often como will require an amp especially if multiple points are involved. The jobs I've done either side of camberwell rd are usually better to Mt Dandenong as you've got a hill between you and como. It goes without saying you need to use a log or similar as there's lots of lowband noise.. trams, trains etc...
mtv Posted April 30, 2007 Posted April 30, 2007 Bit scared to ask, but....what's a log? I would take it to be a log periodic antenna. I know some argue against their use in electrical-interference prone areas and in theory I would agree, however, in practice, I have generally found the opposite to be true, as the log periodic has very low BER, across the bands, they tend to work very well at rejecting impulse noise. (provided you only use band 3/4/5 models, not the ones that are designed to receive bands1/2. I'd also agree with beeblebrox that you are more likely to have better success in Camberwell with signals from Mt Dandenong, than Como.
beeblebrox Posted May 1, 2007 Posted May 1, 2007 yes a Fracarro Lp34H / JTC LP345 or the like, Log Periodic is my antenna of choice for the bulk of digital installs I do from Mt Dandenong. normally Good BER results and fairly flat gain across it's frequency ranges.
V205 Posted May 6, 2007 Posted May 6, 2007 Hi guys, I'm having problem posting a new topic. I've recently moved to Ashwood VIC 3147 to an old house and is having some issue with reception quality. Was at the neighbour's house earlier today and his analog signals are very good except for SBS. My (analog) signal is ok for ABC and SBS and 7,9,10 are terrible. The only ones that I can get digital is SBS1&2, 7,9. 10 and ABC1&2 doesn't work off the Wintel STB. Any advice? Not sure if it's the antenna or the wiring (old and thin) from antenna to the splitter (split to 3 points).
beeblebrox Posted May 7, 2007 Posted May 7, 2007 H? Not sure if it's the antenna or the wiring (old and thin) from antenna to the splitter (split to 3 points). You can't post a new topic until your post count is > 10 . Most likely all of the above..., antenna, cabling and connections... The fact you don't get 10 and abc digital means your antenna isn't designed for ch 11_+12 (ten and ABC Digitial), your poor analogue is indicative of an antenna/cabling problem..
V205 Posted May 7, 2007 Posted May 7, 2007 Thanks for the reply Beeblerox. The funny thing is one of the split (rear room) has a half decent analogue signal for all channels (10 is a bit more grainy) and able to receive all digital channels. Maybe the main point in the lounge has a lot more interferences. The antenna to the splitter on the roof is running on old thin coax. The splitter to the main point in the lounge is RG6 and to the rear room is RG6 also. I'm considering getting the Matchmaster MM01-DC23A, what do you guys think? Regards.

V205 Posted May 7, 2007 Posted May 7, 2007 Alanh, I've gone through the link before your paste. I bought some stuff today, crimp F connectors.. crimp tool... a D23A Matchmaster Digimatch and 50m worth of Beldon RG6-Quad.... matchmaster 4 way F splitter... Just did the F connection (previously saddle) to my STB point and it resolved my digital problem with ABC1&2 and 10. Should be a lot better when I get through all the other stuff, (mostly important would probably be the cable from antenna to the old splitter) and split to 3or4 points... maybe the D23A isn't even necessary. Thanks guys. V205,Read Get the Best Reception, Melbourne and read the links. AlanH

Thanks guys. Obviously fixing your connections put you on the right side of the digital cliff.. by how much only time and weather conditions will tell. The DC23A has Band 1 ie Channel 2 and this can be more likely to pickup external lowband RF interference. In my opinion the DC23 isn't a very good antenna for the Melbourne environment.. from memory of the "gain graph" it's gain is in all the wrong places and in my experience it's performance isn't as good as other matchmaster antennas like the DB19 for example. But if it's Digital you want, go with something that doesn't have Band 1 like the Matchmaster DG21B or LP03F, Hills SMX24B4+ or one of the Log Periodics from Fracarro, JTC, etc
V205 Posted May 8, 2007 Posted May 8, 2007 Hi, my other points are analog signal TV's. Matchmaster sold the DC23A as an antenna which has generally enough power to have multiple outlets.

alanh Posted May 9, 2007 Posted May 9, 2007 V205, These Matchmaster DG21B or LP03F, Hills SMX24B4+ or one of the Log Periodics from Fracarro, JTC antennas will pick up all analog signals except the ABC analog. Surely you could watch the ABC in digital. This will make all your signals stronger. If the signal is still insufficient you can get amplified splitters. AlanH
V205 Posted May 9, 2007 Posted May 9, 2007 Alanh, you mean the digital AND analog (except for ABC analog) signal will be stronger with a Log periodic compared to the DC23A? I suppose I can always get another LP antenna and link it direct to my STB point if the DC23A isn't good enough (which is highly unlikely). It will be a lot easier to do that now that I've got the F type splitters and connections going. 2 Antennas on a pole isn't too much of a problem in terms of inteference?

alanh Posted May 10, 2007 Posted May 10, 2007 V205, You cannot combine those two antennas without producing lots of ghosting and unreliable digital reception. If you want sensitivity and directivity, pick an antenna with the highest number of dB. This will increase the size and price. AlanH
Yarra_south Posted May 18, 2007 Posted May 18, 2007 Question along similar lines... I've moved into a place in South Yarra. I factory reset my teac sd stb, and it's picking up seven, abc, sbs, and ten, all fine... but no channel nine. Now, normally this wouldn't worry me, but the Sopranos will return soon! Any idea what the problem would be? I'm a couple of blocks from the Como building, but there's another big ass apartment block in the way!

Try a manual tune for GTV 9 from como, it's on Ch 51 or 690.5 Mhz, possible your box just didn't scan it properly, or possible you've got an antenna/cabling issue.
