a 1.35 can limit reception of channels at certain times of the day - so you can go for this smaller dish if you can live with not having certain channels (like bc2 and c4) on a 24./7 basis. - as you say "most of the day" - make sure it is not when you will be wanting to watch those channels
generally the minimum requirement is a 1,8... in areas around benidorm a 2.4 is recommended, |
