Old Serious thread here: http://www.satelliteguys.us/free-air-fta-discussion/154409-lowering-lnb-temperature.html

Since I've got a bit of cabin fever :eek:, and this Ice/Snow front hasn't left for a week, I wanted to share some pictures of my iced over dishes. Now to some of you this is a non-story (snow and ice for more than a week but this is a little unusual around here for it to last more than 4 days:eek:)
3" snow yearly is uncommon here in the Portland Metro Area
And snow of that much is usually followed by weeks of freezing rain.

So for the matter that I have have 8" and then a 1/4" of ice, then another 6" and a 1/4" of ice, plus what ever fell today, is quite the odd occasion to say the least. (Not happened in the last 40 years, they say)

Anyway I've got plenty of cooling for my lnb's:cool:

The Starband dish LNB's have almost a 1/2" of ice from the freezing rain.
The reflector itself has had a nice coating of ice for the last week now.

My Dish 500 (love my NASA) got propped up against the Starband after a re-point that made NASA unreceivable :confused: on the Starband

But now that has been repeatedly buried in snow and ice.
Each time I unburied the bare 119 LNB, it reminded me of the old thread.

And I say "RUBBISH" to the idea that cooling LNB's gets better reception. :p:rolleyes:;)
( I'm joking since I've had quite stable reception even with the thick, water-heavy cloud's blowing over.)

Man, I love this hobby

First Pic is Saturdays buried 500 (11" whooo :D)
Second Pic is 7" of snow cooling that bare LNB for 119W (still Saturday)
Third Pic is the rig when I walked out to it tonight to clear it off
Fourth Pic is my yet-to-be-cleaned LNB's for 129W/123W (L-to-R in pic)
Fifth Pic is today's iced over reflector with half of the snow I left on for comparison
Sixth pic is the cleaned-off, iced-over Geosatpro UL1 along with the Gilat and the C120 feedhorn. As well as all of the Tx/Rx piping.

I dunno, any gains there might have been seem to be offset by the snow covering the dishes. I did take the snowblower and make a path out to the dishes so I can keep them clear........I'll have to take a picture of the depth.......I didn't know how much until I cleared a path through the untouched powder down to the bare lawn......IT'S A LOT!!!.
I think in this area that we've already had more snow than we had all last winter.
Global warming? What?!?!
