To start out with, I live in Colorado and I am a Directv subscriber and have a big Slimline dish attached to the side of my house. Had it put there instead of on the roof so I can sweep the snow off of it during the winter. Anyway, I also have an RV and wanted to get a portable dish for the those trips away from home. Purchased a new Slimline with a tripod and a new LNB. Tested out setting it up on my deck, and was able to find the satellites with no problems. Then I tweaked the signals using a meter to get the best reception. Hooked the dish up to the receiver and found the signal strength on the portable to be lower than my regular mounted dish. Scratched my head and thought it might be the LNB or the cables being used. Checked all the cables and connectors and found no issue there. To eliminate the LNB, I swapped it out with the house one and the LNB on the portable dish. The House LNB on the tripod showed lower readings, while the new LNB on the house showed up great. Well, in my eyes, that eliminated the LNB as being the issue and got me into thinking it might be the dish itself. Measuring the dish and comparing all the parameters I found the arm on the portable was about a 1/2 inch shorter than the one on the house. So, I unlocked the LNB from the arm and gently pulled it out as far as I could, and still barely able to lock it in place. Lo and Behold the signal strength increased another 10-12 points on the meter scale. Now I am faced with a dilemma, if the focus on the LNB is that far out, what is my next step? Do I bend the dish a little this way and that (which isn't easy) to see if I can improve the focus, or do I lengthen the arm? Whichever, I figure both are going to cause issues trying to make this thing work. I'm also still trying to figure out how much money the manufacture saved by producing a shorter arm on the antenna assembly. Anyway, I'm just wondering what has anyone else done in this situation, and what suggestions do you have to tackle it?
