I travel full time in my RV and use directv HD with the .72 slimline dish and a dvr+ receiver. I am traveling south for a year with some friends around mexico and centeral america. Can I continue to recieve the regular reception if not the hd with a more sensitive lnb and bigger dish? what would you suggest? If I am going with a universal lnb should I consider adding FTA? what equipment would you suggest.
