dish tv t1020 pixalization issues

got myself a t1020,

but I'm finding the image is pixalizing &/or freezing &/or skipping frequently on all muxes.

the aerial setup for my area (wgtn) is horizontal by default. (i.e. i can pick up prime etc via loop out to the TV)
& the t1020 info page suggest the signal strength is approx 90~95% (but frequently dipping to approx 50~60%) with signal quality relatively constant at 85%

to combat the pixalization on the t1020, I've needed to reverse the polarity of the aerial (i.e. set it vertical instead.) so the signal strength is now only approx 40~50% (but it is relatively steady at these %s) with signal quality remaining relatively constant at 80%.

this fix works, but isn't ideal as, in very strong wind & rain, the kordia mux is still subject to pixalization AND now i can't pick up prime etc via loop out to the TV.

if i get a splitter (so i don't use the loop out), would the signal degrade significantly that the signal strength would no longer fluctuate so wildly?

additional info:
signal is also currently boosted with an indoor amp.

i didn't have this issue with my old freeview stb.

short to buying a new aerial,
any other constructive suggestions would be appreciated.

also i'm finding the audio & image are out by a fraction of a second.

same problem with my t1020.
New aerial rg6 cabling to 1st splitter then to tv, another cable going to 2nd splitter from 1st splitter signal degrade very bad.
on tv connected to 1st splitter signal strength around 65-70, quality around 70-80
I put an in-line amp directly connected to the t1020 and set the t1020 to provide power, this give me a boost of around 5-7% on strength/quality.

Was still getting dropouts and pixilation on 1st tv and no signal on any output connected to the 2nd splitter.

So i put an in-line amp to the input of the 1st splitter and connected the 1st tv (where the t1020 is connected to) to the output of the splitter (one that can provide power across it) from the t1020 and man did that make a difference.

On 2nd splitter(4way) i get signal strength/quality of 70-95/70-80 (where i had no signal before)
TV connected to 1st splitter(2way) pretty much the same as above.

I do still experiance occasional pixilation but no way near the extend i had before.

Before moving my in-line amp adaptor (around $40) i was going to raise the aerial(new 21 element), replace the existing cable from 1st splitter to 2nd splitter and its outputs (which was existing), i ran new cable from aerial to 1st splitter.

So my advice to you is move your amp as close as poss to aerial and ensure your splitter's output can carrier power over it from the t1020 so that you don't have to plug it in to a power source.

good luck...

I sure if i my my in-line amp to directly connect to the aerial then my issues would be solved.

Sounds like you need to return to original polarisation and fit a masthead amp.
Do you have any other aerial on the same pole?
In low signal areas the UHF antenna needs to be on its own well away from any other antennae and obstructions.
