Antenna/Cabling Q

I cant find a better group to pose this on, and TV repair type Qs normally
drive me mad too, so I'm sorry if its out of scope but bear with me - im
going nuts.

Problem: Good reception on non-digi channels but missing large numbers of
digi channels. Removing one of the branches of the antenna cabling sorts
out the one remaining connected TV (which suggests cabling problems on the
disconnected section). But strangely with the other branch disconnected the
disconnected TV recieves (in not THAT bad quality) a full range of non-digi
channels (struggles with all digital ones though). Theres no shorts or
partial shorts on any of the branches and all are using co-ax (though some
bits arent top notch cable, just budget cable).

We're wondering if the signal thats obviously being somehow recieved on the
disconnected branch is causing trouble when reconnected to the main feed.

Any ideas?

Could be simply a low signal level. Considered a line amplifier?

Unfortunately it has an amp (which has died at some point so has just been
removed, which improved but didnt fix the problem)

Having checked the house over we are running non RG6 cable (oldschool brown
stuff, single shielded etc) and have had a fair few probs with impulse
noise so maybe thats the cause...
