Crystal Palace Freeview

Why is it that a friend in Watford gets perfect Crystal Palace
Freeview reception with an old loft-mounted 10 element group A aerial
(with an ancient coax feeder), yet if if I look around her
neighbourhood and elsewhere in north London (say Walthamstow to
Enfield area) I see loads of simply enormous external high-gain
widebands.

Are people being ripped off good and proper by rogue installers?
Or is interference from other another high-power in-band (Group A)
analogue transmitter (e.g. Sandy Heath) a problem?

Watford is a fair way away from the CP transmitter. It may be that the high
gain aerials were/are needed to ensure decent analogue TV pictures.
Additionally, the extra signal allows for splitting the input to more than
one TV without necessarily needing amplification.

Watfor's not that far away compared with other places in CP's range. Watford
is about 22 miles away. I live about 35 miles away, and used to pick up CP
(now use Hannington). Using the inverse sqaure law, that gives me about a
third of the signal as Watfordians.

Although many people in Watford use the Hemel Hempstead relay. A friend of mine
lives in the Garston district, he gets perfect CP reception, (and C5 from
Croydon) using a basic 10 element roof mounted Grp A, yet many of his neighbours
are using HH. I don't know why.
