Montana PBS

[kodaz]

I was playing around with my dish tree (3dishes-1 pole so far) and i had an old metal 24 inch tall superdish . For the heck of it, i set it up on 125 for the pbs channels and the darn thing brings in montana at 60 q on my Openbox. The other tps are same or better including the other S2s. heh, score one for the Openbox!

That's good performance for a Superdish. I wouldn't have expected that dish to receive any S2 reliably.

S2 on a Superdish. Most impressive!

thanks, i wont leave it there permanently, i am betting when that lnb warms up, i wont get it.
I have a crimestar dish that i have been holding for ransom, eventually i will stick that in its place.

Wow, you must be in the center of the footprint. Still zero signal on a fine tuned 4' dish in BC. OETA yes, Montana no.

 

[Cadsulfide]

Pretty impressive aiming, I have one parked at 97W and one at 87W, but could never get a great signal @ 125W.

Keeping the LNB warm is a positive thing.

Keeping the LNB warm is a positive thing.

In terms of keeping condensation out, it is, but keeping it cool would theoretically lower the noise factor. I don't know whether it makes any difference in practice though.

 

[kodaz]

it seems to, when the outside air temp got below 40 or so, my q's went up a bit.
I Am in Pa., mountains. i dont know about the footprint there, later i will check satbeams.
They are not horrible dishes for bieng so short. i did however skew the entire dish, and not the lnb. i wonder if that makes a dif?

Keeping the temperature constant minimizes the drift of the resonator. Some oscillators come with a small heater.

kodaz;
I believe that skewing the dish does make a difference. I have a 90 cm Geosatpro dish that I used for 125W stationary for over a year and got good reception. With this setup, the LNB was skewed, but not the dish. When I added the DG380, the signal was noticeable improved and occasional dropouts on the HD channels were eliminated. With the DG380, the dish skews along with the LNB.

 

[Tron]

Skewing the entire dish makes a greater difference on an oval dish such as the Superdish than it would on a "round" dish. It does improve reception.

That is good info to know, thanks all!
