The symbol shows the location of the Saltdean (Brighton and Hove, England) transmitter which serves 1,500 homes. The bright green areas shown where the signal from this transmitter is strong, dark green areas are poorer signals. Those parts shown in yellow may have interference on the same frequency from other masts.
This transmitter has no current reported problemsThe BBC and Digital UK report there are no faults or engineering work on the Saltdean (Brighton and Hove, England) transmitter.

Which companies have run the Channel 3 services in the Whitehawk Hill transmitter area
A: On any Yagi-type aerial, the dipole is immediately in front of the reflector. On this one it must be contained within the plastic box. The cable always connects to the dipole (perhaps via some other electronics first).
There is a rod on the other side of the boom from that plastic box, but I assume that's an oddly-positioned director - a plain dipole is always split in half, electrically.

David George: The simple answer is money. The commercial multiplex operators don't want to pay the extra money to install and run equipment at all the relay sites. The PSBs are paying more than double the amount the COMs are paying, to reach only about 8.5% more of the population.
The relay sites may be using one fewer channel than before, but the main sites are using two more than before (at full or near-full power). In addition, the government have taken away one-third of the available spectrum in order to reuse it for other services (e.g. mobile phones, wireless broadband). Previously channels 21-68 [48 channels] were used for TV, channels 31-38 are the 'lower released spectrum' or 600 MHz band [8 channels] and channels 61-68 the 'upper released spectrum' or 800 MHz band [8 channels]. That's 16 out of 48 channels no longer used for TV.
The commercial operators were asked at the outset of switchover planning whether they wanted to transmit from any more sites, and they said no. Therefore the frequency plans do not allow space for the COMs to be added later.
C47 (formerly Saltdean C4) has gone to Heathfield, which loses two of its analogue channels in the upper released spectrum. C51 (formerly Saltdean BBC One) has gone to Whitehawk Hill, which lost one analogue channel. C66 is released.
The other issue is feeding the signals to the transmitter. Relay transmitters rebroadcast the signal they receive over-the-air from their parent. It's easiest to do this if they rebroadcast on a different frequency. There are only a very few Active Deflectors, where the same channels are used. The main transmitters are 'line fed' - the data to broadcast arrives via fibre-optic cable. Renting sufficient fibre-optic capacity is very expensive so only done where off-air relay is impossible.
Digital TV does support 'single frequency networks', where multiple transmitters use the same frequency. They have to be very closely synchronized and emit exactly the same signal. Off-air relays *can* be used but again they're very expensive, and they add a processing delay. The window for transmissions arriving from different transmitters is pretty short already.
Even if the COMs decided to add more sites, Saltdean would be way down the list as it is only predicted to serve 1,500 households. That's 1,500 households who are predicted not to be able to get at least one of the PSBs reliably enough from a transmitter that does provide the COMs. Digital UK's prediction is that you are one of these households (the PSBs are shown as meeting the standard from Saltdean, but not from Heathfield, your best source for the COMs).

I am thinking of setting up two aerials pointing to two different transmitters.
I will connect the two cables to a distribution amplifier using a Y piece.
Will the joint siganals be decodable at the set(I use a iDTV).
I am thinking of using a Y piece because I do not have a diplexer.
