Blade 7000S set up and dish config HELP ME !!!!!

Hi all and i hope someone can help me as i'm going out of my mind, i'm new to all this so please forgive me if these seem stupid questions.

Issue 1

Can you use the Blade without having a lan cable attached ie, just use it to view free to air stuff ?

Issue 2

I have an old sky dish and I have tried to connect it to the blade 7000 but I receive nothing, now bear in mind that this dish is about 12 years old the LNB is a sharp single out put, do i need to upgrade the LNB with a new on in order to receive a signal ? especially if i want to view HD channels

issue 3 if you can use just a dish without an cable will i require a viewing card to view free to air programs such as bbc and itv

any help or advice would be greatly appreciated.

we are using the system in a caravan hence no LAN lead

issue 1, yes, should be able to receive a lot of free to air channels without using a viewing card.

issue 2, have you had anything connect to the dish recently? ie a old sky receiver? Is the dish a eliptical dish or the really old round mesh dish. Make sure you reciever is trying to scan the correct satellite for the dish. Elip dish you should scan 28.2 if its a really old round dish it could be astra 19.2.

issue 3, Some channels come under freesat and you will need a freesat viewing card but Itv and bbc should be ok just maybe ch4 and ch5 but it been a long time since I last looked they may be free now.

Thanks Kegnkiwi, got it sorted with the help from a sat finder, turns out the LNB supply needed to be 13v . i have done a scan and found a shed load of channels however 60% are $ id there a way to view or is this where the lan cable comes into play ??
just being greedy :Mad2:
