Sorry if this seems complicated. I have a 5 LNB D* dish. It's output is fed to the home distribution center (left over from cable days). All home runs to receivers start here.

Connected are three old Uniden SD receivers and three D* H20 receivers. All through in-wall RG-59 (I know...). Everything works fine except...the newest receiver is about 100 ft. away from the distribution center, as is another one which works fine. The newest one doesn't work right.

It would not see the satellite at all until I took the BBC out and changed the 20 ft. wall to receiver cable for a 15 ft. one. Then, it sorta worked. I can get all D* SD channels but no HD channels.

Professional installer said there is a weakness in this cable run due (possibly) to a buried splitter somewhere. Transponder levels marginal (~50). Works fine for SD.

Would an inline amplifier work to bring this up to snuff? Can anyone suggest a brand/model? Where should it be inserted (I guess at the start of the cable run at the distribution point)?

Thanks for any help you guys can offer.

A definite......maybe.

First, quality of signal is more important in many regards to signal strength (and the D* "signal strength" is more an indication of Quality than actual Signal).

Second, there is no way you will be getting HD to work without the BBCs, so its no surprise that you lost HD then.

Third, because of the way that they are stacking the signal, the RG59 and/or splitters could cause issues.

Bottom line, on the 100 foot away H20 that works, what are some of the readings from an even and odd transponder on 99a/99b, 101, and 103a/103b
transponder. How does that compare to the readings on the same transponder on the non-functional H20 WITH BBC attached?

Please post both sets of numbers.

You can buy an LA2150A flat, 20dB gain, wideband low-power inline amp or an LA2150B wideband inline amp with 4dB of slope on "the net" for about ten bucks plus shipping. Just Google the part number and price for a list of lots of suppliers. You would put it on the multiswitch output of the suspecyed weak line. For cable loss compensation it is better to use the "B" model rather than the "A".

Unfortunately for you, it more likely is a buried splitter and if it is, it is likely that the inline amp will not provide a wholly adequate remedy, but if it would be very costly to replace the home run, then you might as well try the inline amp first.

I bought a LA2150B as suggested. It worked perfectly and I get all HD channels now (after reinstalling the BBC). The amp gave enough signal strength to allow the BBC to be reinstalled.

Thanks for the suggestion.
