I am forced to do a manual install (I can't work directly with DTV because my apt. complex has a deal with an outside company to purchase packages and install DTV and they don't offer HD). I have 2 receivers on my account at my other house which I want to use at my new apartment and they are the HR23-700 and a R15-500. Which dish do I need to buy? I noticed there are several types. Probably for my case the smaller the better. Also, as far as tripods go, are they all the same or are there specific ones I should look for?
