Not recently, but in the analogue days lots of ghosting issues as I recall.
Its not that far from Crystal Palace after all, probably still has lots of
tower blocks as well.

The Croydon (Old Town) relay on a tower block is a couple of streets
away from Bramley Hill precisely because of the towers to the north
east, but I live on the old side and get excellent reception from CP.

Does anyone know why analogue Channel 5 used Croydon instead of Crystal
palace for the London area? Wasn't there enough room on the tower for
the aerial? Did it cause any problems for those near wanting to receive
signals from both with the same aerial, or would they be close enough
for it not to matter?

The original 4 channel aerial and feeders at CP couldn't handle any more
power and it didn't cover the new frequncy used by C5. To fit an omni
aerial right round the mast would have probably been very expensive but
one could easily be put at the top of Croydon.

Now they just have some of the worst definition of any freeview channels
accourding to an ncis fan.


C5 HD seems on a par with the other HD channels.

The result was appalling reception to the south, I can see the tower
and have an outside aerial, but still got a snowy picture. It
disappeared completely one night in heavy rain, since NTL had a tiny
satellite dish for reception at Beulah Hill. After that, it got line
fed, and eventually they wound up the power so reception got better.


That wasn't the problem, the problem was rain fade on their uplink site
at Winchester, it knocked out the feed nationally.

They added a reserve uplink at Croydon, which naturally was line fed, so
obviously the UHF Tx at Croydon was fed by that too.
