Multiswitch?

[ajah]

I set up my 5lnb but am having problems bringing in 119. I broke the tweak piece so it makes it harder. However I have a triple lnb that will bring in 119 is there anyway I can use that dish to add with the other one to bring in the sats that aren't coming in properly. If so what will I need and how do I do it. I currently have H20 and Hr20 receivers. Will a multiswitch work to bring in what the other won't and also how many short cables from each dish would I need and would the multiswitch be ok sitting outside in snowy weather.
