As stated you will need at least a 30" dish. I would highly recommend spending the extra $20.00 and going for the 90cm dish (36"). Second what language does she speak? There is a ton of
Spanish language channels out there but most I have found are Mexico, South America and the Cuba area islands. I happen to know Spanish is big in the Phillipinnes.
Consider the
DTV dish a learning experience

I went all out and bought a KTI 3 lnb DTV dish as I found info on the net that such a dish would work for FTA. Then I found out the truth

Mine lays on the back deck along with a
Dish 500 dish and a single lnbf dish (not sure if it is DTV or DN). The latter two were given to me. Have thought about putting up the single lnbf dish for the music channels on (I think) 119. But then again I have plenty of music without it.
