  1. Problem: 20 year old RG59 air spaced cable run through 15mm ID (about) conduit in next door unit APPEARS "stuck". In my unit I was able to remove mine and replace with RG6 using cable lubricant without any problems. Probably 2 x 90 degree bends as conduits are set in concrete floor - down - 90 - along - 90 - up. Total length along about 7 metres, ups about 80 cm each. Questions: 1. How much "pull" can you apply to the RG59 before it will break? 2. Any tips on how to make the old cable come out more easily?
  2. Thanks for the heads-up on 2016. I did ask for the 2007 two weeks ago at the Warringah Library and was told that Saiglobal ceased allowing Council libraries to access/carry the standard online on 01 July 2016 although it is still available at the state library. Will try again today with the correct year. I don't like my chances as they did do a thorough search and it was the head librarian I was talking to.
  3. G'day Alan, Long time no see! I spoke with you on this forum way back regarding the MATV system in Willandra Village (260 units) as I fought with management to get it upgraded. Long story short - we now have a fibre backbone and fibre feeds to 22 clusters where media converters then feed - Wait for it - mainly RG59 to the units. The fibre has made a fast improvement NOW but I am certain that the old 'legacy' RG 59 (air) aged about 20 to 30 years and PAL wall plates will eventually breakdown and cause big problems. Do you have a copy of the AS/NZS 1367:2007 standard? I would like to be able to quote chapter and verse (I reckon it is Section 5 pages 55 to 70) on what we all know to be a totally unsatisfactory set up so that residents are not saddled with future maintenance costs. HELP!!!!
  4. Just to close this thread off. I moved the Sharp to the main bedroom where it performs well in the spot that we really want to put it. Bought a Yamaha MCR-040 with an external antenna connection for the living room. With this I had no problem placing the wire dipole antenna in the optimum position and connecting using a RG6 'flylead'. Results excellent with all signal strengths above 90+. Advice to anyone contemplating DAB+ in difficult reception areas - make sure the set is fitted with an external antenna connection. Thanks.
  5. Oooops Not quite there yet. Decided to return the tuner and go for a Mini System unfortunately with only a fixed wire antenna. With about 1 metre of the wire vertical in the ideal reception position I am getting signal strengths of 90-100 [100 is Max] but the system is about 1.5 metres from the 'entertainment unit'. Anywhere but this position and the signal strength drops off rapidly. I have tried to extend the wire antenna but without success. Tried connecting to the 'bunny ears' by inserting the antenna wire into the centre pin of a PAL connector - no good. Should I earth the connector body? The system is the Sharp XL-DAB1H. Any ideas please?
  6. Thanks mtv and all for your replies. I tried a DAB+ tuner today with an external antenna using 'bunny's ears' and got good readings inside my unit so it looks like I can hold off on a roof top for now. All I now have to do is to try and make them inconspicuous
  7. I have recently been trialling DAB+ reception at Cromer, Northern Beaches Sydney. FM reception is poor and I have used a Matchmaster 03MM-FM3 [horizontal] for the past 5 years to get marginal FM quality. I have just finished looking at DAB+ signal strengths using a PURE One Mi. Although the maximum signal strength on the read out appears to be 2 bars [out of 5?] the sound quality is much better than my FM. This signal strength is as good as it gets with clear line of sight to Beacon Hill which blocks the view if central Sydney. I am now looking to get a DAB+ tuner to replace my FM one; it will probably work better with an external antenna. Questions: 1. If I turn my 03MM-FM3 to vertical will it do the job? 2. Is a steady 2 bars out of 5 a good enough signal - I assume that it is a bit like the 'cliff edge' with DTV. If you have any STABLE signal it is all OK.
  8. Thanks Alan. Sorry to be so dumb but is not that via CABLE only, NOT satellite here in Sydney?
  9. HD via Satelite??? Is this now possible for mere mortals? I am under the impression, maybe wrongly, that HD is not available via Satellite for FOXTEL etc. at present. Will it be so in the future for the household or only via a re-transmission. Mike.
  10. 1. Does anyone else have an outside antenna - not a dish? 2. Do you have a "body corporate" or some such? If so ask them.
  11. Thanks dig2all, You talk about "old hot chassis tvs". 1. How old and are they still being made? 2. Do the bog standard PAL wallplates [HLP1] currently fitted provide isolation? 3. Are we trying to keep these "leakage voltages" from getting into the system from old TVs, from affecting new HDTVs connected to a system which also has old TVs connected to it or both?? Enlightenment greatly appreciated
  12. G'day Rusty, First an apology for the long post but….. As a member of a residents committee in a retirement village of some 225 units I sympathise with your problem with the body corporate but envy you in only dealing with those of your own ilk rather than a financial conglomerate that is only interested in the bottom line. Like you our MATV system was hopelessly outdated and had grown in an uncontrolled way. Much of the cabling, even in the trunks, is RG59 air-spaced with some RG6 dual shield. There are isolated runs of RG11 in some parts of the trunks. There were shocking examples of bad connections; F-type connectors crimped with vice-grips, conductors and shields soldered and taped over to make a split, innumerable loose connections and corrosion in wall plates. All wall plates are loop-through PAL. We had been fighting with management over our problems for over three years before a proper attempt was made by a reputable specialist company to examine the problem and propose solutions. One of the requirements was to provide analog as well as digital signals because of the number of analog TVs [and incidentally VCRs] in use in the village. In hindsight it may have been better just to go digital and provide all who wanted them a STB but I am not sure how that would have satisfied the VCR requirement. At the heart of the matter was the distribution cabling and this was clearly recognized but, because of a total lack of diagrams and in the main the excessive cost of replacement, it was agreed to use the current cabling if possible. Once the headend was producing an output meeting the optimum standards of AS/NZS 1367:2007, critical cabling and hardware causing non-receipt of signals to units would be replaced. We embarked on a two stage approach. First the existing two antennas were replaced with commercial quality antennas specific to the digital bands; the height was also raised slightly and they were directed optimize the signal levels and picture quality from each. Second was to supply & install a COFDM digital to Analogue Processor that took the 5 best quality digital services and transfer them to analogue signals to replace the standard analogue channels 2, 7, 9, 10, 28. Concurrently install a channel processing headend to translate the current digital services to new channels whilst retaining the integrity of the digital service. The reasons for this were given as: 1. The COFDM to Pal converted signals will be the same programming as what is on the analogue channels with the benefit however of being digital quality (ie. No ghosting) 2. This 2 part process will allow both the digital and analogue channel frequencies to be pulled in closer together, reducing the system slope and minimizing the attenuation of the signals once they leave the headend by keeping the channel selection as low and compact as practical (higher frequencies = higher loss through the distribution cabling and greater spread of frequencies creates slope related issues throughout the system) The new system will also allow for the reticulation of digital services as the native digital format, allowing users the option of installing a set top box also if they wish. From previous experience of the contractor and readings taken at a number of unit outlets, it was anticipated that the changes to the headend would precipitate a large degree of compliance amongst the network and that remaining faults could generally be fixed in batches (e.g. the replacement of a single cable or amplifier would fix a ‘cluster’ of issues). After some initially poor performance in some clusters, this did in fact eventuate although there are still occasional glitches in the system which I believe will increase over time. Most units still have RG59 cable and PAL outlets. Although I have not been given the actual figures, based on early quotes, I believe the cost was in the order of $15,000 but I could be way out. It was management’s intention that eventually all cabling would be upgraded to AS/NZS 1367:2007 but as this will cost in the $100K area and as it has so far proved impracticable within budget to trace the cable runs I am not holding my breath. What I have been pushing for is that, whenever a unit is refurbished [generally at a cost of about $30000 +], the cabling and wallplates be replaced with RG6 quad, taps and F-type connectors. Currently we have a number of units under refurbishment with wiring over 15 years old and the old RG59 air spaced and loop-through PAL plates are being left in place ! To summarise. The phased approach has worked to a considerable degree - as Debruis has confirmed. Nevertheless our committee is still pursuing the real solution which will only be achieved when the distribution cabling is fully at AS/NZS 1367:2007 standard. If you would like to discuss further please send me a PM. Mike.
  13. Thanks for your reply M'bozo and all the others that have raised the point about "isolation". As a non-techo I am a bit lost on the isolation but will pass it on to someone else who should know. M'bozo is the only one that has realised that it is the "90 deg" configuration of the "out" to the "tap/in" [take a look at his link] that enables this to fit into a limited space. I hope that the 17MM-EMxx series is still available after 9 years. Looks like a phone call to Matchmaster
  14. I have just found a modification to a wall plate that provides a compact solution to the problem of replacing "loop through" wall plates in older buildings when distributing DTV. In one on the units of my retirement village a grandson who is obviously quite savvy has installed for a resident a made up an antenna wall plate using a REGAL RDCUV-6, 5-890Mhz, 6db TAP [Mini directional coupler, "L" configuration]. I have found this tap on http://www.arrisi.com/product_catalog/tw_d...TWS%20Sec_E.pdf [ a copy of this page is attached and also a JPG of the plate]. Visit My Website 1 - PDF Visit My Website 2 - JPG The single leg connects to the TV and this tap does fit guite snugly into the current "hole in the wall". So far I have been unable to find this type on any Australian web site. Do any of the professionals out there know where they may be sourced? PS. Sorry the other side picture failed.
  15. Thanks for your full reply Col. Unfortunately the "star" setup is not an option as I am in a retirement village unit with full double brick walls and concrete floor/ceiling so I have to stick with the trunk and drops as installed. I have just finished completely replacing the trunk which runs in conduit with RG6 quad [it was RG59]. Our village is now in the process of having the full MATV system replaced but this will probably NOT extend to a complete rewire of all units so I am doing my own thing. I will have no problems in getting the launch signal and quality readings when the job is "finished". I may then have to get a pro to insert the taps of I decide to make all outlets serviceable. As I currently only use one outlet [the second in the chain] I have decided to leave the others as "fitted for but not with". The run from the input to my unit goes continuously to my TV wallplate [living room] via the first wallplate [bedroom] but has not been "broken" at that point. I can always have it cut and the tap put in when needed and may even be able to "con" the contractors into doing it for me By replacing the trunk and using a new F type plate at the TV with a RG6 fly lead I have already increased the signal strength [as indicated on the STB meter] by over 10% so am happy with the current setup. We currently only have 2, 7, 9 and 10 in digital [sBS and 44 will be included when the job is finished] and I have signal strengths of 80% to 90% on these four. Thanks again for your advice....Cheers.. Mike.
