GREETINGS, ALL! DirecTV was oh so very gracious last year to provide a NEW dish when we moved to our "vacation" home in NC (not so glamous - inherited 68-yr-old house). Since then we have upgraded to HDTV & the NC dish is not adequate for HD programming. I HAVE an extra dish which appears to be a HD mulit-switch dish that someone gave me, which is labeled "DIRECTV Multi-Satellite KTI". It has the 3 "knobs" on the dish arm extension, BUT has 3 coaxial cables rather than the 2 that my HD set up has. The dish itself is slightly oblong (oval), and has a label that states, "California Amplifier, triple feed, Multi-satellite LNB. Compatible with DirecTV. Model # 150946. There is also a round "sticker" with "REV: 1 12303". My question is: would I be able to replace the old, standard TV dish at the NC house with this Multi-satellite dish? How difficult is it to "aim" for HD-TV signals?? Thanks in advance!!
