I have a legacy shy dish with a shotgun cable.

I have a Gigablue UHD UE 4K UHD.

So all I need to do is to have the LNB switched to https://www.world-of-satellite.co.uk...e-lnb-1-legacy to take advantage of the FBC tuners, using the shotgun cable in place, and just use 1 cable that is the unicable to feed all 8 demodulars?

If / when i move the shotgun cable could connect to a freesat box and both cable could act as universal LNBs for say a humax freesat box?

But main thing is that I can use existing cableing?
