aaron.miller Posted March 30, 2007 Posted March 30, 2007 Hi guys, i have put up a new aerial and my picture is much improved. However i cant get the abc. Signal strength is all over the place. I have the aerial pointing towards willoughby and get 96% quality and level or higher on sbs, 7,9,10 and d44. Seeing as sbs, d44 and the abc all share the same tower why cant i get the abc. The aerial is a jaycar LT-3195 Digimatch VHF/UHF X-type Colinear 27 Element Receives Band 3, 4, and 5 (Channel 6-12 and 28-69) I am in epping. Any ideas Aaron
digitalj Posted March 30, 2007 Posted March 30, 2007 That's weird, I live in Beecroft, and get all channels perfectly, it's quite possible ABC might be just a touch too strong, If you can get to a Dick Smith or Tandy, pick up a variable attenuator, and stick that in just before your stb, and try again, I'd suggest you manually tune ABC on 226500KHz, leave it there and try adjusting the attenuator, and you should hopefully start to get picture, if this doesn't help, just take it back for a full refund.

Any ideas Aaron Aaron, depending on where in Epping you're located, you might consider adding a high-gain UHF antenna pointed towards Wollongong (Knights Hill). This would get you ABC from there, which transmits on UHF-51, as well as the 'regional versions' of Seven (Prime), Nine (WIN) & Ten (SC Ten). Before you consider this option, check out the FM reception of 94.9, 95.7, 96.5, 97.3, 98.1 & 98.9 on your FM radio, which transmits from Knights Hill, and should give quite a good indication on what your digital TV reception from Wollongong would be like at your location. Just a thought.
aaron.miller Posted March 30, 2007 Author Posted March 30, 2007 thx guys, i went and bought a Variable Attenuator from jaycar part # LT3050. it didn't help abc and dropped the signal level of the other channels. Is that the right thing. Aaron
aaron.miller Posted March 30, 2007 Author Posted March 30, 2007 oh and dtvcampbelltown as to getting wollongong i have a hill directly south of my house so i doubt that would work. Aaron

Any ideas Aaron try replacing cable from wall plate to receiver some can be faulty from new and\ while some signal can be passed some times its as if particular frequencies are attenuated more than others its worth a try there should be 8db gain on VHF12 with that antenna. if you did it yourself double check coaxial connections are good and clean with no loose braid 'shorting' signal. cheers alan
alanh Posted March 31, 2007 Posted March 31, 2007 aaron.miller, The ABC and SBS are on the Gore Hill tower not the Willoughby tower. You mention quality but not signal strength. It may be that the signal from the ABC is a little stronger, so an attenuator between the STB and the wall would be worth a try. They cost around $10 from electronics shops. AlanH

AlanH He's already tried an attenuator and it didn't fix it. Stated here: http://www.dtvforum.info/index.php?s=&...st&p=630403
alanh Posted March 31, 2007 Posted March 31, 2007 digitalj, So what are the relative signal strengths? AlanH
digitalj Posted March 31, 2007 Posted March 31, 2007 digitalj,So what are the relative signal strengths? AlanH Not sure what he's signal levels are, as he hasn't stated, but if it helps, I live in Beecroft, and have no amp or attenuator, and get perfect reception on all channels.
aaron.miller Posted April 1, 2007 Author Posted April 1, 2007 thanks guys for all your help, relative signal strengths on all channels except for abc are 98% and the signal meter doesn't move its steady. For the abc the meter goes up and down like a yo yo up to 80% then down to 40% and all points in between. Are their any particular brands of cables that are better for the bit from the wall plate to the stb. The actual cable from the aerial to the wall plate is the old cable that had the old analogue aerial attached to it. I figured i would try it with that and if the signal was too low then buy some new quad shield cable. As im getting 98% signal strength as well as "quality"i figured the cable was okay. With the metal braid that show bend back on itself over the black insulation right by about 10mm right. so its touching the inside of the metal f connector at the other end to the copper inner core?? I assumed it was just like a uhf aerial for my car. Aaron
