Starchoice reception

[mazjim]

I've recently purchased a HDTV and I'm using StarChoice HDef channels for the first time. Also, I'm located where reception is limited. Over the years I've had no trouble receiving the reg channels but now, with Hdef, I'm having some problems. If I "fine tune" the dish I can receive all the chans reasonably well at night but during the day some work and some don't. When I look at options 6-4-7 the db varies from around 2.4(not working) to as much as 3.2(works fine).

Okay, so here are my questions.

I was talking to someone today who mounted a e60 lnb on a e75 dish and claims it works fine. I got me thinking about trying a e75 lnb on a round 100cm dish. Would this likely work or help my signal strength?

Also, I recall having a higher signal strength when I was using a stacked lnb. If I switched back to stacked from quad would it likely help?

Now here's a really out in left field question. Has anyone tried adding something additional to the e75 dish that might give it more surface area and possibly a better signal?

Stacked lnb

Does anyone know if the SC stacked lnb is likely to have a stronger signal and possibly work better with Hi Def?

nope. All the stacked LNB did was allow you to use a satellite grade splitter to run 2 receivers off one LNB.

When they changed out the satellite at 111.1 (the HD one) and changed to 8PSK the signal seemed to go down at the edge of the footprint

2 to 2.5 dB lower by my estimates, so even a 75-E antenna can be marginal
in many locations...and is why we strongly recommend 2 separate antennas
of larger diameter. They're easier to align, and if you get at least an 85 or 90 cm model, you will be in far better shape signal-wise. Look at the link listed
above for some technical explanation in full detail.

Added input...you are measuring C/N levels in the +3 and +4 dB range.
Motorola receivers mute out at any level below +2.0, and unless you
want constant interrupted reception, a system with clear-sky levels lower
than a +5.0 dB needs to be upgraded. It takes very little precipitation and/or
cloud cover to knock out 2 dB of signal, and your numbers are proof of these mathematical calculations. Get a bigger pair of antennas !!
