2 way TV signal booster

[DIYspanner]

Recently got a 2nd hand booster to supply a couple of TVs yet when plugged into one TV with around 50% signal and 100% quality on its own without the booster, the booster is reducing the signal quality to around 60%. The led lights on the booster so I presume there's no issue with power.

Is that the norm for a booster of this type or is it merely faulty? ...... I'd presumed a signal booster would provide near 100% for both signal and quality.

what issues are you having, i would have thought with 100% quality , even though the signal strength is down - should get an ok picture ?

is it just to be able to connect up 2 TV's to the 1 aerial

Although the Freeview website quotes 'Signal strength: Good' for all channels and both TVs are Freeview enabled, the booster does not perform as well as I expected.

Aerail lead plugged into the booster and the two cables out to the TVs. I do however have suspicion that some older cable already in the wall down to the ground floor is not the best. Its not screened. The cable I've used to the other TV is WF100.

i used that cable when i redid all the rooms , and had an amp - 8 way in loft
but you still get 100% quality , with just the cable, on both the TVs -
are you daisy chaining through PVR or something else ? -
is it an outside aerial - has it moved at all ?

i'm sure someone more knowledgeable will be along -
