I posted about this earlier in the year or late last year (can't remember) but I can't seem to find anyone who has actually used this product. http://www.sterenusa.com/bssd/news/NPR_PDF/221-365clamponmount.pdf I may be mistaken but I thought I read on here that this was not a DirecTV approved item. Can someone confirm or refute that? If I was to purchase this on my own would DirecTV do the installation for me? I'm in an apartment and we have a "no-drilling" rule so this is pretty much my only hope to get a Slimline up. Also, if I hired a private installer to do the job would this void my service protection agreement? Thank you in advance.
