Interesting difference between Viasat-1 and Viasat-2

I had Viasat-1 for years; Exede before that, Wildblue before that (and even a C-band 2-meter dish before that).  I upgraded to Viasat-2 this past May.  Today it's snowing steadily but lightly here (New Hampshire), and my service slowly degraded until it finally went out at about 10am.

I walked down the hill (100') to check the dish; it was full of snow, so I knocked it out, and it connected back up (with nearly the normal SNR).  My Viasat-1 service would never have this problem; that satellite is so low on the SW horizon from here that the dish ends up being vertical.  Viasat-2 is almost due south from here, and so much higher in the sky; the dish tilts back enough that it collects snow.

This was a new problem for me, so I thought I'd share in case other folks experience the same issue.  Luckily my dish is pole mounted, so I can easily brush if off.

This style of heater has worked good for me. https://www.amazon.com/gp/product/B00G6S50X2/ You might also want to try and get some rainX and give the dish a nice coating.

A heater would be nice.  Unfortunately, the dish is 100' from the house (with no power nearby), and my house is off the grid, powered by solar panels (so an electrically heated load is not really practical except when the sun is shining, and then I don't need the heater :-)

On that Amazon page, it had a couple of interesting related products.  Anyone have any experience with these?

I am also off-grid only plug in the dish heater as needed. I tried the second one the sock like device and it fails in freezing rain, turns hard. Dish heating has worked the best for me. Winter is my peak power time from hydro so I get to waste power.

RE: C-band 2-meter dish

Well then, invert it and make a Domed Gazebo


Here's a 3 meter Gasebo

That is pretty cool!  Unfortunately, by old 2-meter dish is an ugly grey plastic material.  I used to think I would use it for satellite TV; is that still even a thing?  Or has it all gone to Dish and Direct-TV style services?

RE: old 2-meter dish

In earlier days, satellites had a 3-degree separation, and later, it was changed to a 2-degree separation.  If this dish is still true in form, it might work on KU frequencies, but not so well on C-band frequencies.  Last I knew, a subscription service was still available, but a  3-meter dish, and larger, would be required, along with a Digital FTA Receiver.  Only subscription service I'm aware of is here. but if I were to use this service, I would buy a good 3.7 meter or so sized dish.

LyngSat lists satellites, and some of these birds would have a few in the clear broadcasts.  Some of these channels are broadcasting in very high data rates, which just means a larger dish is required, with good receiver, and PLL LNB to lockin.

I've had to clean off both my sat internet and sat TV dishes numerous times today.  Wet, sloppy snow is the worst for reception.  I could have four of five inches of the fluffy stuff built up on both and they would still work, but a quarter inch of this stuff and all bets are off.   :(

Ain't that the truth.  I guess it's all part of the cost of living in the country.  I'm just glad I insisted on a pole mount; the installer (for Viasat-2) REALLY wanted to put it on the roof.

My DirecTV dish is on my roof, unfortunately.  But, my roof is being replaced next year and I'm having them move the dish to pole mount.   That will be SOOO much nicer.  :)

Roof mounted dishes in areas that get snow and ice are so impractical. I am so glad that both my dishes are mounted low enough that I can easily brush them off from he ground using a brush mounted on a piece of PVC conduit.

That is how I do it. I have a low roof and use a brush on an extension pole.

Luckily, my internet dish is located on a pole right outside and to the side of my bedroom window.  I can actually open the window, reach out with a pole, and tap the dish to get the snow off without ever having to go outside.  Yes, it's the epitome of laziness.   :) 

My DTV dish was originally installed right next to it, but they installed it in December, and when the trees started filling in during the Spring it started having interference, so they had to move it to the roof.  It should have never been put where it was in the first place.   

When I upgraded my internet nearly two years ago and they had to change the aim of the dish to the new satellite I had to cut down a tree that was in the way.  That wasn't fun.  I didn't have a chainsaw and had to instead use Black & Decker Alligator Loppers.  A foot thick tree with Alligator Loppers.  SMH.  But, it worked.

spray pam on the dish and the snow can slide off if its tilted enough
